RTAX1000SL-1CGS624B - Rad-Tolerant FPGA 1M Gates | Microchip
The Microchip Technology (formerly Actel/Microsemi) RTAX1000SL-1CGS624B is a radiation-tolerant FPGA offering 1,000,000 equivalent system gates with 12,096 Configurable Logic Blocks (CLBs) and an additional 125,000 ASIC gates, housed in a 624-ball ceramic column grid array (CGS624) package. A radiation-tolerant FPGA (Field-Programmable Gate Array) is a programmable logic device engineered to survive the total ionizing dose (TID) and single-event effects present in space-flight radiation environments. Within the semiconductor hierarchy, it sits under programmable logic > FPGA > radiation-tolerant FPGA, and the RTAX-S/SL family is qualified for mission-critical defense and space programs, including DLA Standard Microcircuit Drawing qualification (5962-0422006QUA) per MIL-PRF-38535 Class V. Key features include live-at-power-up operation thanks to the anti-fuse (flash-free) fabric, a true single-chip form factor that removes the need for external configuration devices, and low static power consumption - all decisive advantages over SRAM-based FPGAs in orbit. The device is built on a digital CMOS process derived from the commercial Axcelerator architecture. Technically, the RTAX-S/SL fabric provides embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, and chip-wide highway routing, enabling high-performance signal processing at densities up to 4 million system gates across the broader family. The SL variant adds enhanced radiation hardness for longer-duration missions. Typical applications include satellite payload processing, spacecraft command and data handling (C&DH), telemetry encoding/decoding, and space-borne instrumentation where reconfiguration after launch is not required but survival across a 10+ year mission is. Design consideration: the anti-fuse technology is one-time programmable - thorough pre-flight verification with Microchip (Microsemi) Libero design tooling is essential, and space-grade availability is constrained, so early procurement planning is advised.

Key features include SEU-hardened flip-flops that eliminate the need for Triple Module Redundancy (TMR) in many designs, SEU immunity to specified LET thresholds with SEU rates below 10-10 errors per bit-day, true single-chip operation, and live-at-power-up behavior enabled by the non-volatile antifuse programming technology. Unlike SRAM FPGAs, the antifuse configuration cannot be disturbed by radiation-induced configuration upsets, removing the need for external configuration PROMs. The SL variant is the low-power derivative of the RTAX-S family, reducing static power consumption - a critical advantage for battery- and solar-powered spacecraft. System-level features include embedded SRAM with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic datapaths. The device is programmed once at the factory or programming house via the antifuse layer, providing very high design security. Typical applications include satellite payload data processing, spacecraft telemetry and command interfaces, sensor signal processing in orbital platforms, and fault-tolerant control logic in deep-space probes. Design consideration: as an antifuse (one-time programmable) device, design freezes must be complete before programming - no post-deployment reconfiguration is possible, so flight-design verification with prototype devices is essential.

It is fabricated on a 0.15 um CMOS process and operates from a 1.5V core supply. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the harsh radiation environment of space: it combines an anti-fuse-based, non-volatile fabric (live-at-power-up, no configuration flash to upset) with a single-chip form factor that avoids the cost, mass, and power of external configuration devices. In the space-electronics hierarchy, it sits alongside radiation-hardened ASICs but offers lower NRE cost and faster time to orbit. Key features include the Axcelerator-derived fabric with embedded SRAM featuring built-in FIFO control logic, segmentable clocks with chip-wide highway routing, and dedicated carry logic for arithmetic. These map directly to the needs of flight payloads that require high gate density, deterministic timing, and single-chip reliability. Technically, the RTAX-S/SL family is based on Microsemi (now Microchip) commercial Axcelerator devices, letting designers prototype on commercial equivalents using footprint-compatible adaptor boards and an EDIF netlist and pinout converter before committing to flight silicon. This mitigation flow is described in Microchip application note Prototyping for RTAX-S and RTAX-SL Devices, which materially reduces program risk. Typical applications include satellite payload processing, spacecraft command and data handling, remote sensing and imaging pipelines, and telemetry/tracking/control electronics, where 1M gates of immediate-on-boot logic fits data formatting and bus interface roles. A key design consideration is that the 624-ball ceramic column package requires strict board-level mounting practice; ceramic column BGA rework is specialized, so pinout lock-down early in the flight design cycle is essential.

A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SEE) environment of orbital and deep-space missions. Within the space electronics hierarchy, RTAX-S sits under radiation-tolerant FPGAs -> space-grade programmable logic -> flight hardware, alongside one-time-programmable antifuse competitors and flash-based alternatives such as ProASIC3-based prototyping solutions. Key features include a true single-chip form factor, live-at-power-up operation, and low-power consumption. The antifuse programmable interconnect is inherently immune to configuration upsets, eliminating the need for external configuration storage such as PROMs or flash - a decisive weight, power, and reliability advantage in spacecraft avionics. The metal-sealed ceramic column package supports high pin-count, high-IO flight boards. Architecturally, the RTAX2000S derives from the commercial Axcelerator family, embedding SRAM blocks with built-in FIFO control logic, segmentable clock resources, and chip-wide functionalities, fabricated in 0.15 um CMOS with a 1.5 V core per the RTAX-S/SL datasheet family. Typical applications include satellite payload data processing, spacecraft command and data handling (C&DH), telemetry/tracking/command interfaces, and radiation-hardened bus controllers - anywhere millions of system gates must operate reliably under radiation for multi-year missions. Design consideration: RTAX-S devices are one-time-programmable (antifuse); use the companion PROTO/prototype parts or an Aldec flash-based adaptor for in-system iteration before committing to flight silicon.

RTAX2000S-1CG624PROTO - 2M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology RTAX2000S-1CG624PROTO is a radiation-tolerant, antifuse-based FPGA delivering 2,000,000 equivalent system gates, 32,256 logic cells (21,504 CLBs) and up to 540 kbits of embedded SRAM, housed in a 624-ball ceramic column grid array (CCGA-624) package with speed grade -1. The PROTO suffix denotes an engineering-prototype qualification flow intended for early system development and validation. A radiation-tolerant FPGA is a field-programmable gate array qualified for the space-flight radiation environment. Within the power-management hierarchy of onboard digital electronics, RTAX-S devices sit at the top: one-time-programmable antifuse interconnect makes them live-at-power-up and immune to configuration upsets that affect SRAM-based FPGAs, eliminating the need for external configuration storage. Key features include total ionizing dose tolerance of 300 krad (functional) and 200 krad (parametric), single-event upset rates below 1E-10 errors per bit-day, up to 684 user I/Os across the family, and embedded memory blocks with optional EDAC protection. Performance reaches up to 350 MHz in system-level designs, based on the commercial Axcelerator architecture. Architecturally, the RTAX2000S uses a segmented clock structure, chip-wide synchronization outputs, and FIFO control logic integrated into the embedded SRAM, allowing single-chip implementations that would otherwise need glue logic and external memory. Typical applications include satellite payload processing, spacecraft bus control, telemetry and telecommand interfaces, and orbital instrument controllers, where low power, single-chip reliability, and radiation tolerance are mandatory. A key design consideration: antifuse FPGAs are one-time programmable, so complete timing closure and in-system verification should be completed before committing a flight lot.

RTAX2000S-1CGS624V - 2M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology RTAX2000S-1CGS624V is a radiation-tolerant FPGA delivering approximately 2,000,000 equivalent system gates with 21,504 configurable logic blocks (CLBs) on a 32,256-cell architecture, housed in a 624-ball ceramic column grid array (CG624) package. It operates from a nominal 1.5V core supply (1.425V to 1.575V) across a military space temperature range of -55C to +125C with speed grade -1. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environments of space flight, where single-event upsets (SEUs) and total ionizing dose (TID) would corrupt or destroy standard commercial silicon. Within the power/semiconductor hierarchy, the RTAX-S family sits under radiation-tolerant programmable logic, alongside flash-based and antifuse-based space FPGAs, and is a direct descendant of the commercial Actel Axcelerator family architecture. Key features include SEU-hardened flip-flops that eliminate the need for triple-module redundancy (TMR) in many designs, embedded SRAM blocks with built-in FIFO control logic, segmentable clock conditioning circuitry, and chip-wide highway routing. The family reaches up to four million equivalent system gates, and the RTAX2000S additionally provides about 250,000 ASIC gates of companion capacity per Microchip USA data. Live-at-power-up operation and a true single-chip form factor remove the external configuration device required by SRAM FPGAs, increasing board-level reliability. The device is fabricated on a CMOS process and programmed via antifuse technology, which is inherently immune to configuration upsets - a decisive advantage in orbit where configuration scrubbing is costly. Performance is preserved at high density, making the RTAX2000S suitable as the main payload processing element. Typical applications include satellite payload data processing, spacecraft bus control and telemetry, orbital instrument interfaces, and launch-vehicle avionics - anywhere high gate counts must coexist with proven radiation tolerance. Designers should plan I/O bank voltage budgets early: the CG624 package dedicates hundreds of balls to I/O and power, and supply rails must stay within the 1.425V-1.575V core window under all load transients.

The Microchip Technology RTAX2000S-1CQ256PROTO is a prototyping-grade device for the RTAX2000S radiation-tolerant FPGA family, providing 21,504 configurable logic blocks (CLBs), 2,000,000 equivalent system gates plus 250,000 ASIC gates, in a 256-pin ceramic CQ256 package. PROTO devices let designers validate RTAX-S designs on commercial hardware before committing to one-time-programmable antifuse flight units. A radiation-tolerant FPGA is a programmable logic device qualified for space-flight environments, where high-energy particles cause single-event upsets (SEU) and total ionizing dose (TID) degradation. Within the power-management hierarchy of spacecraft avionics, these devices sit above general-purpose FPGAs in reliability and are the direct descendants of the commercial Microsemi (Actel) Axcelerator architecture, retaining library compatibility with it. Key features of the RTAX2000S family include nonvolatile, highly reliable antifuse technology that is live-at-power-up (no configuration flash or external boot device), up to 540 kbits of embedded SRAM with optional EDAC protection, and SEU-hardened registers that reduce or eliminate the need for triple-module redundancy (TMR). The family is specified for total dose of 300 krad (functional) and 200 krad (parametric), with SEU rates below 1E-10 errors per bit-day on flight-grade variants. Architecturally, the RTAX2000S is based on the Axcelerator fabric: fine-grained logic modules, segmentable clock resources, chip-wide routing, and embedded FIFO control logic. Note that although RTAX-S devices are library-compatible with Axcelerator, internal timing differs significantly, which is exactly why Microchip application note AC170 recommends prototyping on devices such as this PROTO unit and the companion Aldec ACT-H3Ki-CQ256 reprogrammable adaptor before flight-device programming. Typical applications include satellite payload data processing, spacecraft attitude control and telemetry interfaces, radiation-heavy orbital and deep-space missions, and high-reliability defense electronics. The 2M-gate density accommodates bus controllers, image preprocessing pipelines, and glueless interfaces to space-grade memories. A key design consideration: PROTO units are intended for engineering validation, not space flight; order the corresponding flight suffix (V/B/E variants) for qualification hardware. This page adds value beyond the manufacturer datasheet by consolidating distributor availability, drop-in same-package alternatives, prototyping-workflow guidance, and procurement FAQs for this hard-to-source aerospace component.
RTAX2000S-1CQ256V - 2M-Gate Rad-Tolerant FPGA CQ256 | Microchip
The Microchip Technology (Actel/Microsemi) RTAX2000S-1CQ256V is a radiation-tolerant, antifuse-based field-programmable gate array (FPGA) with approximately 2,000,000 equivalent system gates, 21,504 configurable logic blocks (CLBs), and support for an additional 250,000 ASIC gates, housed in a 256-pin ceramic quad flat package (CQ256). A radiation-tolerant FPGA is a programmable logic device qualified for the space-flight environment, where cosmic rays and trapped protons threaten SRAM-based logic. Unlike SRAM FPGAs, the RTAX-S family uses one-time-programmable antifuse interconnect, giving a true single-chip form factor (no external configuration flash), live-at-power-up operation, and intrinsic immunity to configuration upset - key reasons it is the FPGA of choice for space designers. Key features include the 2M-gate fabric with embedded SRAM blocks that include built-in FIFO control logic, segmentable clock resources, and chip-wide highway routing inherited from the commercial Axcelerator family. The -1 speed grade and C (standard) temperature/quality grade designation target space flight programs where flight heritage and established documentation dominate procurement decisions. Architecturally, the RTAX2000S descends from the Actel Axcelerator architecture, combining fine-grain logic modules with dedicated embedded memory and high-performance routing. Because configuration data is hard-wired via antifuses at programming time, the device boots functional logic within microseconds of power application - a decisive advantage over SRAM FPGAs that require an external configuration source vulnerable to SEU. Typical applications include satellite payload data processing, spacecraft bus control and telemetry, deep-space probe avionics, and launch-vehicle electronics. The Aldec ACT-H3Ki-CQ256 adaptor enables reprogrammable flash-based prototyping (ProASIC3E) in the same footprint before committing to one-time programmable flight parts. Design consideration: antifuse FPGAs are OTP - validate the design fully in the Aldec prototype flow before programming flight units.

RTAX2000S-1CQ352V - 2M-Gate Rad-Tolerant FPGA | Microchip
The Microchip (Actel/Microsemi) RTAX2000S-1CQ352V is a 2,000,000-gate radiation-tolerant CMOS FPGA with 21,504 configurable logic blocks (CLBs) and 32,256 logic cells, housed in a 352-pin ceramic CQFP (CQ352) package. It belongs to the RTAX-S/SL family, which provides live-at-power-up, single-chip operation for space-flight systems. A radiation-tolerant FPGA is a programmable logic device designed to survive the total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SEU) environments of low-Earth-orbit and deep-space missions. Within the power-management-free fabric hierarchy, the RTAX-S family descends from the commercial Axcelerator architecture and occupies the rad-tolerant segment between commercial FPGAs and fully rad-hard ASICs, allowing designers to implement mission logic without the NRE and schedule cost of full-custom silicon. Key differentiating features include flash-free antifuse-style one-time programmable configuration, live-at-power-up operation that eliminates the external configuration device required by SRAM FPGAs, low static power consumption, and embedded SRAM blocks with built-in FIFO control logic. The RTAX2000S device in the CQ352 hermetic ceramic package supports segmentable clock resources and chip-wide network routing for large space payloads. Technically, the fabric is based on Axcelerator-class logic modules organized into clusters, with embedded SRAM blocks distributed across the die. The '-1' speed grade defines the timing performance bin, and the 'V' suffix denotes the radiation-tolerant qualification variant per Microchip ordering conventions. Designers implement designs using Synplify/Libero flows and map them onto the RTAX-S macro library. Typical applications include satellite payload data processing, telemetry and telecommand (TM/TC) controllers, spacecraft bus avionics, and instrument interface bridging on orbital platforms where SEU mitigation and hermetic packaging are mandatory. A critical design consideration: the device is one-time programmable, so design freeze and extensive qualification (including SEU rate analysis with Microsemi tools) must precede flight-lot programming.

Key features include 2 million system gates for complex onboard processing, embedded SRAM blocks with built-in FIFO control logic, segmentable clock circuitry, and chip-wide synchronization, all derived from the commercial Axcelerator architecture. The device belongs to the RTAX-S/SL and RTAX-DSP family, which reaches densities of up to four million equivalent gates for space-based payloads. Low static power consumption and single-chip integration reduce mass, board area, and radiation-sensitive component count. The antifuse fabric combines high performance with configuration upset immunity, while qualification against defense and space quality flows (QML Class V heritage per the Microchip DLA cross-reference documentation) supports mission-critical flight programs. Typical applications include satellite payload processing, telemetry and command systems, spacecraft bus controllers, and radiation-hardened signal processing chains, where deterministic live-at-power-up behavior and single-chip redundancy savings are decisive. When designing with this device, plan the one-time programming flow carefully: use the RTAX2000S-1LG1152PROTO prototyping device to validate designs before committing flight units, since antifuse programming is irreversible.

It is purpose-built for space-flight systems where live-at-power-up operation and single-event upset (SEU) immunity are mandatory. A radiation-tolerant FPGA is a programmable logic device qualified to survive the total ionizing dose (TID) and single-event effects found in orbital and deep-space radiation environments. Within the programmable logic hierarchy, the RTAX2000S-1LG624V sits in the space-grade class above commercial FPGAs, derived from the commercial Axcelerator family and manufactured in CMOS with one-time-programmable antifuse interconnect. Key differentiating features include nonvolatile antifuse technology that requires no configuration device and is live at power-up, embedded SRAM blocks totaling up to 540 kbits with optional EDAC protection, and total dose tolerance of 300 krad (functional) and 200 krad (parametric). SEU immunity is specified at less than 1E-10 errors per bit-day, among the best in its class. Architecturally, the RTAX-S/SL family pairs Sea-of-Modules logic with segmentable clock resources, chip-wide highway routing, and built-in FIFO control logic on embedded SRAM. The -1 speed grade provides high-performance synchronous operation while the ceramic package with column-grid interconnect withstands launch vibration and thermal cycling typical of spaceflight missions. Typical applications include satellite payload data processing, spacecraft bus controllers, telemetry and telecommand interfaces, and radiation-tolerant glueless bridges between processors and high-speed peripherals. Designers select the RTAX2000S when logic capacity beyond RTAX1000S is needed without moving to the four-million-gate RTAX4000S. A key design consideration is that antifuse FPGAs are one-time programmable: use the companion RTAX2000S-1LG624PROTO or a reprogrammable ProASIC3E-based Aldec prototyping adaptor during development, then program flight units last. Plan I/O assignments early because CG624 pin tables define dedicated configuration and special pins that must be connected per the datasheet.

The Actel (Microchip Technology) RTAX2000S-CG1152V is a radiation-tolerant FPGA offering 2,000,000 equivalent system gates, 21,504 CLBs, and 32,256 logic cells in a 1152-terminal ceramic metal-sealed cofired CBGA (CG1152) package. The device provides 684 inputs and 684 outputs and operates from a 1.5V nominal core supply across a -55C to +125C military temperature range. A radiation-tolerant FPGA is a programmable logic device qualified for space-flight environments, where exposure to cosmic rays and trapped-particle radiation would upset or degrade commercial silicon. Within the semiconductor hierarchy, it sits under FPGA -> programmable logic IC -> digital integrated circuit -> semiconductor. The RTAX-S/SL family was developed from Microsemi (Actel) commercial Accelerator AX technology and is a standard choice for spacecraft payload computing, telemetry, and bus electronics. Key features include high-density two-million-gate capacity, embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic. As an anti-fuse, one-time-programmable device it is live-at-power-up, requiring no external configuration flash, which is a decisive advantage in single-string space systems where a configuration read failure would be mission-ending. Architecturally, the RTAX2000S combines a low-power flash/anti-fuse CMOS process with a fine-grained Sea-of-Modules fabric. Radiation tolerance is achieved through the anti-fuse programming technology, which is inherently immune to configuration upsets, while the fabric is hardened against total ionizing dose (TID). Designers implement triple-module redundancy in logic where single-event effects must be mitigated at the application level. Typical applications include satellite payload data processing, spacecraft on-board computers, radiation-hardened bus interfaces, sensor-data acquisition in orbital platforms, and secure aerospace communication systems, where single-chip logic density and power efficiency at 1.5V core are critical system drivers. Design consideration: anti-fuse programming is one-time, so functional verification must be completed on a reprogrammable prototyping adaptor (for example Aldec flash-based ProASIC3E adaptors) before flight-unit programming; the prototype device mirrors the RTAX footprint for board-level test.

A radiation-tolerant FPGA is a field-programmable gate array designed to survive the total ionizing dose (TID) and single-event effects found in spaceflight orbits without the cost and schedule of a full radiation-hardened ASIC. In the programmable logic hierarchy, the RTAX-S family sits above commercial FPGAs (such as the Axcelerator family on which it is based) and below fully rad-hard devices, making it the workhorse choice for satellites, rovers, and scientific payloads. Key features include up to four million equivalent system gates across the family, embedded SRAM with built-in FIFO control logic, segmentable clocks, chip-wide highway routing, and dedicated carry logic. The anti-fuse, one-time-programmable architecture provides live-at-power-up operation and true single-chip form factor, eliminating the need for external boot configuration devices and reducing susceptibility to configuration upsets. Architecturally, the RTAX2000S is based on the Actel commercial Axcelerator family, enabling a documented design flow that lets customers prototype on the commercial Axcelerator equivalent and then target the same design to the RTAX-S/SL device, supported by Actel Extender circuit boards that map the commercial package footprint to the RTAX-S package footprint. This flow provides a cost-effective path from prototyping to space-flight silicon. Typical applications include satellite payload data processing, spacecraft bus controllers and telemetry interfaces, and deep-space scientific instrument control, where low power consumption, single-chip integration, and radiation tolerance are mandatory. A key design consideration: RTAX-S devices are one-time programmable, so full design sign-off (simulation, timing closure, and hardware prototyping, e.g., with the Aldec ACT-H3Ki-CG624 adaptor that mimics the CG624 footprint) must be completed before programming flight units.
