RTAX4000SL-CG1272V - 4M-Gate Rad-Tolerant FPGA CGA-1272 | Microchip
The Microchip Technology (Actel/Microsemi) RTAX4000SL-CG1272V is a radiation-tolerant FPGA with 4,000,000 equivalent system gates and 40,320 logic cells, housed in a 1272-pin ceramic column grid array (CGA-1272) and rated for operation from -55C to +125C. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation and heavy-ion environment of orbital and deep-space missions. Within the space electronics hierarchy, it sits alongside rad-hard ASICs and COTS+FPGA wrappers as a primary payload-data and control logic platform, and the RTAX-S/SL family pioneered single-chip, live-at-power-up antifuse programmability for spacecraft. Key features include SEU-hardened flip-flops that largely eliminate the need for Triple-Module Redundancy (TMR) in user logic, immunity to single-event upsets up to a specified LET threshold with SEU rates below 10-10 errors per bit-day, and true single-chip operation with no external configuration device. The antifuse architecture is live at power-up, an important attribute for launch vehicles and satellites where boot time and configuration-readout vulnerability matter. Technically, the RTAX-S/SL family is derived from the commercial Axcelerator fabric and combines the 40,320-cell core with embedded SRAM blocks featuring built-in FIFO control logic, segmentable clock resources, and chip-wide highway routing for low-skew global signals. The CMOS process targets high performance at low static power, and the -55C to +125C ceramic package supports the thermal environment of spaceflight assemblies. Typical applications include satellite payload data processing, spacecraft bus control and telemetry, launch-vehicle avionics, and deep-space science instruments - anywhere high logic density must coexist with tolerance to single-event effects. When designing with this device, plan the I/O bank voltages and remember that the antifuse fabric is one-time programmable, so the design must be fully verified via the Aldec flash-based ProASIC3E prototyping adaptor or simulation before committing flight units.

RTAX4000SL-CQ352EV - 4M Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology RTAX4000SL-CQ352EV is a radiation-tolerant antifuse FPGA from the RTAX-SL family delivering 4 million system gates (40,320 logic cells) on a 0.15 um process with a 1.5V core supply, housed in a 352-pin ceramic quad flat pack (CQFP) package with enhanced (EV) screening for spaceflight programs. A radiation-tolerant FPGA is a programmable logic device engineered to survive the ionizing radiation environment of space, including total ionizing dose (TID), single-event latch-up (SEL), and single-event upset (SEU) effects. Within the power-management hierarchy of a spacecraft avionics system, the FPGA sits between radiation-hardened microcontrollers and application-specific ASICs, offering ASIC-like reliability with FPGA-style development cycles. The RTAX-SL family is the low-power evolution of the original RTAX-S family, succeeding Actel/Microsemi technology now maintained by Microchip Technology. Key features include live-at-power-up operation via non-volatile antifuse programming, meaning no external configuration flash is required and the device is immune to configuration-memory upsets at turn-on. The 4-million-gate fabric implements dense combinational and sequential logic, on-chip triple modular redundancy (TMR) can be applied by design tools, and the ceramic CQFP-352 package provides hermetic sealing and excellent thermal performance for vacuum environments. Technically, the device uses a 0.15 um CMOS antifuse process with a 1.5V core and I/O banks supplied at 2.5V, supporting common spaceflight interface standards through flexible I/O standards. Clock management and embedded block structure support high-reliability signal processing payloads. Because antifuse configuration cannot be reprogrammed in flight, design flows emphasize extensive simulation and the manufacturer's footprint-compatible prototyping methodology using equivalent Axcelerator-family commercial parts. Typical applications include satellite on-board data handling, payload processing, telemetry and telecommand interfaces, spacecraft bus control, and radiation-tolerant glueless integration replacing dozens of discrete logic devices. Design consideration: pin assignment must be locked early, since antifuse devices are one-time programmable and the EV screening flow requires qualified lot acceptance before assembly.

RTAX4000SL-LG1272V - 4M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology (Actel/Microsemi) RTAX4000SL-LG1272V is a radiation-tolerant, antifuse-based FPGA offering 4,000,000 equivalent system gates, 60,480 logic cells, and 40,320 CLBs, housed in a 1272-pin ceramic column grid array (LG1272) package qualified for space-flight systems. A radiation-tolerant FPGA is a programmable logic device engineered to survive the ionizing radiation environment of space, including total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SEU) effects. Within the programmable logic hierarchy, the RTAX-S/SL family sits above commercial FPGAs in reliability class, serving as the mission-critical processing, telemetry, and control backbone of satellites and space probes. The RTAX-S/SL and RTAX-DSP family is based upon the commercial Microsemi Axcelerator architecture and reaches densities of up to four million equivalent system gates. Key features of the RTAX4000SL include true single-chip form factor, live-at-power-up (LAPU) operation, and low power consumption - the SL (low-power) variant further reduces static power versus the standard RTAX4000S. System-level features include embedded SRAM with built-in FIFO control logic, segmentable clocks, chip-wide highway routing, and dedicated carry logic for arithmetic datapaths. Architecturally, the device uses antifuse one-time-programmable interconnect, which is inherently immune to configuration SEUs - a decisive advantage over SRAM-based FPGAs in orbit, since no scrubbing of the configuration bitstream is required. Metal-to-metal antifuse elements also present low capacitance, supporting the high performance inherited from the Axcelerator family. Typical applications include satellite payload processing, spacecraft command and data handling (C&DH), bus avionics, and instrument control in low-Earth-orbit and deep-space missions where radiation tolerance and single-chip integration are mandatory. A key design consideration: because the device is one-time programmable, engineers must prototype on flash-based ProASIC3E devices using the Aldec/Microchip adaptor board methodology and the EDIF netlist and pinout converter documented in Microchip application notes before committing to antifuse programming. This page synthesizes verified distributor data, family cross-reference options, and practical space-design notes not found in the manufacturer datasheet, giving engineers a single self-contained reference for the RTAX4000SL-LG1272V.

The AMD XC7A75T-2FGG484I is an Artix-7 field programmable gate array (FPGA) with 75,520 logic cells, 285 user I/O pins, and 3,870,720 bits of block RAM. It is supplied in a 484-ball FBGA (FGG484) package, uses a 28nm CMOS process, operates from a 1V core supply, and is rated for industrial temperature from -40C to +100C. The '2' in the part number denotes the -2 speed grade, the fastest standard option for this device family. A field-programmable gate array (FPGA) is a reconfigurable semiconductor device that implements digital logic by configuring a fabric of LUTs, flip-flops, block RAM, and DSP slices through a bitstream. FPGAs fill the design gap between ASSPs and ASICs: they provide parallel execution, low-latency I/O, and field upgradeability. In a system hierarchy, the FPGA often sits beside an embedded processor, handling high-throughput signal conditioning while the processor runs control stacks. Key features of the XC7A75T-2FGG484I include 3,870,720 block RAM bits, 285 versatile user I/Os with LVCMOS/LVDS and other standard interfaces, and integrated clock management tiles containing MMCM and PLL circuits. The FGG484 package enables easy migration between selected Artix-7 family members, reducing redesign risk when scaling density. All packages are lead-free (Pb-free) options. The Artix-7 architecture is optimized for low-power, cost-sensitive applications while retaining DDR3/DDR4 memory interfaces, multi-gigabit transceivers where available, and PCIe hard blocks in larger devices. The 28nm high-k metal gate process balances static and dynamic power. Designers use AMD Vivado Design Suite for synthesis, implementation, and bitstream generation, with support for IP cores such as MIG, AXI interconnects, and error correction. Typical applications for the XC7A75T-2FGG484I include industrial motor control and factory automation, software-defined radio baseband processing, machine vision and video pipelines, medical imaging front ends, and test and measurement instrumentation. The industrial temperature range makes it suitable for harsh environments in transportation, energy, and rugged communications. When designing with this FPGA, pay close attention to power integrity: decouple the 1.0V VCCINT rail with multiple low-ESR ceramic capacitors and follow AMD's PCB design recommendations. The FGG484 package must be assembled with proper BGA reflow profiles, and the JTAG/configuration pins should be made accessible for system-level debug and field updates.
