The V suffix denotes qualification screening for flight programs; the -1 speed grade balances performance and timing yield across the military temperature range of -55C to +125C with a nominal 1.5V core supply. Typical applications include satellite payload data processing, spacecraft bus controllers, telemetry and telecommand interfaces, and radiation-tolerant glue logic consolidation replacing multiple ASIC or SSI devices on orbital platforms. Design consideration: prototype using the equivalent commercial Axcelerator device with Microchip Extender adaptor boards, then transfer the verified netlist to the RTAX-S device for flight production; budget long lead times for V-grade screened parts.

RTAX4000S-CG1272V - 4M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology RTAX4000S-CG1272V (originally Actel/Microsemi) is a radiation-tolerant FPGA with 4,000,000 equivalent system gates, 40,320 configurable logic blocks (CLBs) in a 60,480-cell CMOS architecture, housed in a 1272-terminal ceramic column grid array (CBGA1272) package with a 1.000 mm terminal pitch and a nominal 1.5 V core supply, rated from -55C to +125C. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the total ionizing dose (TID), proton, and heavy-ion environments of orbital and deep-space missions. Unlike commercial FPGAs, rad-tolerant devices such as the RTAX-S family combine space-qualified manufacturing with anti-fuse One-Time Programmable (OTP) technology, giving designers a true single-chip, live-at-power-up solution without external configuration memory. Key features of the RTAX4000S include the 4 million gate capacity - the largest density in the RTAX-S family - low-power CMOS operation, live-at-power-up (LAPU) startup, and embedded SRAM blocks with built-in FIFO control logic. Segmentable clock conditioning circuits and chip-wide highway routing support large, high-performance spaceflight designs. Architecturally, the RTAX4000S is based on the commercial Actel Axcelerator family, adapted for radiation environments. The anti-fuse fabric makes configuration permanent at programming time, eliminating configuration upsets from SEUs of a configuration element and removing the need for an external boot flash - a critical reliability advantage over SRAM-based space FPGAs. Typical applications include satellite payload processing, spacecraft avionics and bus controllers, telemetry and telecommand interfaces, and instrument data acquisition where single-chip integration and radiation tolerance are mandatory. Design consideration: because the fabric is OTP, all logic must be finalized before flight programming; use Microchip (Microsemi) Libero IDE with radiation-aware design practices and SEU mitigation such as triple-module redundancy (TMR) on critical registers.

RTAX4000S-CQ352V - 4M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology (Actel/Microsemi) RTAX4000S-CQ352V is a radiation-tolerant, antifuse-based FPGA with 4,000,000 equivalent system gates, 40,320 combinational logic blocks, and 60,480 logic cells, housed in a 352-pin ceramic column grid array (CQ352) package qualified for space-flight applications. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environment of space, including total ionizing dose (TID) and single-event effects (SEE). Within the power-management hierarchy of spacecraft electronics, the RTAX-S family sits alongside rad-hard ASICs and flash-based space FPGAs, offering one-time-programmable (OTP) antifuse technology that is immune to configuration upsets - a key advantage over SRAM-based FPGAs in orbit. Key features include CMOS antifuse architecture that is live-at-power-up with no external configuration device required, true single-chip form factor reducing board area and BOM cost, embedded SRAM blocks with built-in FIFO control logic, segmentable clock conditioning circuitry, and chip-wide highway routing for high fan-out signals. The RTAX-S/SL and RTAX-DSP family is based on Microsemi's commercial Axcelerator architecture, delivering high performance at densities up to four million equivalent system gates. Device variants such as RTAX4000S and RTAX4000SL share the same silicon and are distinguished by ICCA current screening limits at 125C final electrical test, allowing programs to select the appropriate screening condition. Typical applications include satellite payload processing, spacecraft bus control, telemetry and telecommand interfaces, and radiation-tolerant glue logic replacing multiple rad-hard ASSPs in low Earth orbit and deep space missions. Design consideration: the OTP antifuse fabric means programming is final - use the Microchip/Libero design flow with simulation and, where available, flash-based ProASIC3E prototyping adaptors (e.g., Aldec) before committing flight units.

RTAX4000SL-1CG1272B - 4M Gate Rad-Tolerant FPGA CCGA-1272 | Microchip
The Microchip Technology (Actel/Microsemi) RTAX4000SL-1CG1272B is a radiation-tolerant FPGA from the RTAX-SL family offering 4,000,000 equivalent gates, 40320 logic cells (CLBs), 0.15 um flash-based antifuse technology, and 1.5 V core operation in a 1272-pin CCGA (ceramic column grid array) package. A radiation-tolerant FPGA is a programmable logic device engineered to survive the harsh radiation environment of space: total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SEU) conditions that would disable a standard commercial FPGA. Within the power-management hierarchy of spacecraft avionics, the RTAX-SL family sits alongside rad-hard ASICs as the programmable logic of choice for space-flight payloads, orbiters, and scientific instruments. Key features include the 4M-gate / 40320-cell fabric of the RTAX4000SL die, live-at-power-up operation enabled by non-volatile antifuse programming, true single-chip form factor with no external boot configuration device, and low static power consumption. The SL variant is a low-cost, fixed-fabric version of the RTAX-S family, targeting high-volume space programs where unit cost and schedule matter. Technically, the device uses Actel 0.15 um 7-layer metal antifuse process technology. Unlike SRAM FPGAs, the antifuse fabric is one-time programmable and inherently immune to configuration SEU upsets, so only flip-flop SEU mitigation (such as triple modular redundancy in the user design) is required. The CCGA-1272 ceramic package with solder columns accommodates the large I/O count and thermal cycling of launch environments. Typical applications include spacecraft on-board data handling, payload processing, sensor and instrument interface control, and bus avionics for LEO, GEO, and deep-space missions. Design consideration: one-time programmability means the bitstream cannot be re-flown; rigorous place-and-route signoff and SEU-hardened design methodology (TMR, EDAC) are mandatory before committing to flight units.

A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the heavy-ion and proton environments of space flight, where commercial devices would suffer latch-up, gate rupture, or accumulated single-event effect (SEE) failures. Within the programmable logic hierarchy, the RTAX-SL family sits in the space-grade FPGA tier above commercial-temperature ProASIC/AX lines, using antifuse one-time-programmable technology for live-at-power-up operation and inherently SEU-immune configuration storage. Key features include 0.15 um CMOS process geometry for a balance of density and radiation hardness, a 1.5V core supply for low power consumption critical to orbital missions, and the ceramic CQFP package providing hermetic sealing and high lead-count I/O suitable for socketed or soldered flight assemblies. Architecturally, the RTAX4000SL combines Sea-of-Modules logic tiles with embedded SRAM blocks and clock-conditioning resources, letting designers implement high-throughput signal processing, bus interfaces, and telemetry control on a single-chip platform. Because configuration is stored in antifuse elements rather than SRAM cells, the device is immune to configuration upsets, reducing external mitigation overhead. Typical applications include satellite payload data processing, spacecraft command and data handling, launch-vehicle avionics, and radiation-exposed instrumentation where MIL-STD-883-class screening and extended temperature operation are mandatory. A key design consideration: antifuse FPGAs are one-time programmable, so design freeze, sign-off simulation, and programming-yield management are part of the flow, and prototype programming must be performed via Microchip (Actel/Microsemi) certified programming hardware. This page synthesizes distributor part data, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet, per Microchip datasheet DS2169 (RTAX-S/SL and RTAX-DSP Radiation-Tolerant FPGAs).

The Microchip Technology RTAX4000SL-1CQ352V is a radiation-tolerant, antifuse-based Field Programmable Gate Array (FPGA) delivering 4,000,000 equivalent system gates, 40,320 CLBs (60,480 logic cells), and -1 speed grade performance in a 352-pin ceramic CQ352 package with V-level space qualification. A radiation-tolerant FPGA is a programmable logic device engineered to survive the high total ionizing dose (TID), heavy-ion latch-up, and single-event upset (SEU) environments encountered in Earth-orbiting and deep-space missions. Within the product hierarchy, the RTAX4000SL-1CQ352V sits in the RTAX-S/SL family, which Microchip (formerly Actel, then Microsemi) positions as the space-flight counterpart of the commercial Axcelerator FPGA line. Key features include true single-chip operation enabled by antifuse programming (no external configuration PROM required), live-at-power-up (LAPU) behavior for critical boot logic, embedded SRAM blocks with built-in FIFO control logic, and segmentable clock regions that simplify timing closure at high logic utilization. Architecturally, the device is fabricated in a CMOS process and inherits the Axcelerator fabric structure: asea of logic modules with dedicated carry chains, embedded FIFO/ECC-capable SRAM, and chip-wide routing. The SL suffix denotes the enhanced reliability lot flow developed for the RTAX-SL generation, improving antifuse uniformity and tolerance to space radiation effects relative to the original RTAX-S devices. Typical applications include satellite payload data processing, spacecraft bus controllers, instrument interface bridging, and reconfiguration/telemetry logic on launch vehicles and deep-space probes, where SEU-hardened fabric and low static power are essential. A key design consideration is that antifuse devices are one-time programmable: verification must be exhaustive before flight-unit programming, and prototyping is normally done on the pin-compatible Axcelerator commercial device using Microchip's adaptor-board methodology.

The Microchip (Actel/Microsemi) RTAX4000SL-1LG1272EV is a radiation-tolerant FPGA from the RTAX-SL family offering 4 million system gates, 40,320 logic cells (60,480 logic elements per some listings), 0.15 um antifuse CMOS technology, and 1.5 V core operation, housed in a 1272-pin LGA (LG1272) package. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the harsh radiation environment of space, where cosmic rays, trapped protons, and heavy ions would corrupt or destroy standard commercial devices. Within the power-management hierarchy of spacecraft avionics, these devices sit at the top of the programmable-logic taxonomy: FPGA -> radiation-tolerant FPGA -> space-flight programmable logic. The RTAX-SL family succeeds the RTAX-S family with lower static power consumption, making it the FPGA of choice for space designers who need single-chip, live-at-power-up logic. Key differentiating features include true single-chip operation (no external configuration PROM required thanks to antifuse, one-time-programmable interconnect), live-at-power-up behavior that eliminates configuration boot delays critical for spacecraft safety, low-power 0.15 um CMOS processing, and SEU-protected flip-flops when used with the family's mitigation libraries. The 1272-connection LGA package provides very high I/O density for large payload architectures. Technically, the RTAX4000SL uses Microchip's axcelerator-derived architecture: VersaTiles (fine-grained logic modules) combine with embedded SRAM blocks and high-performance clock-management circuitry. Because the antifuse interconnect is programmed once, the device is immune to configuration upsets, a fundamental reliability advantage over SRAM FPGAs in orbit, though designers must still apply TMR/SCRUB design practices for register-level single-event upset mitigation. Typical applications include satellite payload processing and telemetry formatting, spacecraft command-and-data-handling (C&DH) units, sensor-interface electronics in low-Earth-orbit and deep-space missions, and launch-vehicle avionics where the -1 speed grade and EV screening flow support demanding timing and quality requirements. When designing with this device, remember that antifuse programming is irreversible: prototype on the footprint-compatible RTAX-S Prototyping device (e.g., RTAX4000SL-CQ352PROTO family approach using the adapter-board methodology in Microchip's Prototyping for RTAX-S and RTAX-SL application note) before committing to flight parts.

Designers implement designs using Libero SoC and prototype on footprint-compatible ProASIC3/axcelerator-based flow as described in Microchip's prototyping application note. Typical applications include satellite payload data processing, spacecraft bus controllers, telemetry and telecommand interfaces, sensor front-end signal processing, and reconfigurable computing modules on Earth-observation and science missions. A key design consideration is lead time: space-grade RTAX devices are built to order with long manufacturing cycles, so early order placement and a prototyping migration strategy (adaptor board plus EDIF netlist conversion) are strongly recommended. This page synthesizes verified distributor data, drop-in same-package alternatives, pricing tiers, and engineering design guidance not found in a single manufacturer datasheet, giving buyers and space-systems engineers a one-stop reference for the RTAX4000SL-CG1272B.
RTAX4000SL-CG1272E - 4M-Gate Rad-Tolerant FPGA CCGA-1272 | Microsemi
The Microsemi (Actel, now Microchip Technology) RTAX4000SL-CG1272E is a radiation-tolerant FPGA from the RTAX-SL family delivering 4 million system gates, 40320 logic cells (60480 sequential logic cells), and a 1.5V core supply in a 1272-pin ceramic column grid array (CCGA) package with extended temperature rating of -55C to +125C. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the single-event effects and total ionizing dose encountered in space flight systems. Within the programmable logic hierarchy, the RTAX-SL sits above commercial FPGAs (which lack SEU hardening) and serves as the on-board computation, telemetry, and control backbone of satellites and deep-space probes. Key features include SEU-hardened flip-flops that eliminate the need for Triple-Module Redundancy (TMR) in most designs, single-event upset immunity up to the specified LET threshold with an SEU rate below 10-10 errors per bit-day, and true single-chip, live-at-power-up operation thanks to flash-based Axcelerator-style architecture with antifuse programming. The 0.15um CMOS process keeps static power low, a decisive advantage for spacecraft power budgets. Architecturally, the device builds on the AX cell structure with logic modules, embedded SRAM blocks, and high-performance clock resources, allowing glue logic, bus interfaces, and real-time controllers to be consolidated into one ceramic package. The CG1272 column-grid format provides robust mechanical attachment and thermal performance through PCB reflow, suited to launch vibration environments. Typical applications include satellite payload data processing, spacecraft attitude control units, telemetry/command (TM/TC) interfaces, and instrument control in low-earth-orbit and deep-space missions. The extended -55C to +125C rating covers both cold soak and eclipse heating cycles. Design consideration: the part is one-time programmable (antifuse), so prototype on the RTAX4000SL-1CG1272PROTO variant or the footprint-compatible Axcelerator adapter-board methodology before committing flight units.

RTAX4000SL-CG1272EV - 4M-Gate Rad-Tolerant FPGA CCGA-1272 | Microchip
The Actel (now Microchip Technology) RTAX4000SL-CG1272EV is a radiation-tolerant FPGA from the RTAX-SL family delivering 4 million equivalent system gates and 40,320 logic cells in a 1272-pin ceramic column grid array (CCGA-1272) package, fabricated on 0.15 um flash-based technology with a 1.5V core supply. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environment of space: galactic cosmic rays, solar particle events, and trapped protons in Earth orbit. Within the semiconductor hierarchy, the RTAX4000SL-CG1272EV sits at the top of the programmable logic taxonomy - FPGA -> radiation-tolerant FPGA -> space-flight FPGA - and is a direct descendant of the commercial Axcelerator architecture from Actel, later Microsemi and now Microchip Technology. Key differentiating features include SEU-hardened flip-flops that eliminate the need for triple-module redundancy (TMR) in much of the design, immunity to single-event upsets to a specified LET threshold with SEU rates below 10-10 errors per bit-day in typical orbits, embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic chains. Technically, the device uses antifuse-based one-time programmable interconnect, which gives it live-at-power-up (LAPU) operation - configuration data cannot be upsets in flight because no external configuration flash or SRAM configuration image must be reloaded. This true single-chip form factor removes the radiation-hardened configuration memory that competing SRAM FPGAs require, reducing board area, weight, and boot risk. The 0.15 um process keeps static power low, an important budget item on solar- or battery-limited spacecraft. Typical applications include satellite payload data processing, spacecraft on-board computers and telemetry formatting, instrument control in deep-space probes, and fault-tolerant glue logic bridging rad-hard processors to sensors and downlink subsystems. The -55C to +125C ceramic package operating range supports launch and eclipse thermal environments. Design consideration: because the part is one-time programmable, radiography and prototype validation on the footprint-compatible Axcelerator adapter-board flow is essential before committing flight units; order engineering-variant (E) devices for this purpose.
