RTAX2000D-CQ352V - 2M-Gate Rad-Tolerant FPGA CQFP352 | Microchip
The Microchip Technology RTAX2000D-CQ352V is a radiation-tolerant, antifuse-based FPGA offering 2,000,000 equivalent system gates, 29,568 logic cells, and 19,712 configurable logic blocks (CLBs), housed in a 352-pin ceramic quad flat pack (CQFP352) with 0.500 mm terminal pitch. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environment of space, where total ionizing dose (TID) and single-event effects would degrade or destroy commercial silicon. Within the semiconductor hierarchy, the RTAX2000D-CQ352V belongs to the RTAX-S/SL and RTAX-DSP family of rad-tolerant FPGAs, derived from the commercial Axcelerator architecture, and sits in the broader category of programmable logic devices (PLDs) alongside CPLDs and structured ASICs. Key features include one-time-programmable antifuse configuration, which is inherently immune to configuration memory upsets caused by single-event effects; a nominal 1.5V core supply (1.425V to 1.575V range); and embedded SRAM blocks with built-in FIFO control logic for on-chip data buffering. The 'D' designation denotes the die lot, and the 'V' suffix indicates the qualification screening flow applied at final test. Architecturally, the device uses segmentable clock resources and chip-wide highway routing to distribute high-speed clocks and wide buses with low skew, supporting system-level integration typical of space-flight payload and platform electronics. Typical applications include satellite payload data processing, spacecraft bus control electronics, telemetry and telecommand interfaces, and radiation-hardened signal processing chains where reprogrammable SRAM FPGAs are unacceptable due to upset sensitivity. A key design consideration is that antifuse FPGAs cannot be reprogrammed after programming; design flows therefore rely on the footprint-compatible prototyping methodology using adaptor boards (such as the Aldec ACT-H3Ki-CQ352) before committing flight hardware.

RTAX2000DL-CQ352B - 2M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology RTAX2000DL-CQ352B is a radiation-tolerant antifuse FPGA from the RTAX-DSP family delivering 2,000,000 equivalent system gates organized as 19,712 CLBs, with up to 120 DSP mathblocks performing 18-bit x 18-bit multiply-accumulate at 125 MHz, housed in a 352-terminal ceramic quad flat pack (CQFP) with a 0.500 mm terminal pitch. A radiation-tolerant FPGA is a programmable logic device qualified for spaceflight environments, where total ionizing dose (TID), single-event effects, and reliability dominate the design hierarchy. The RTAX family sits within the broader taxonomy of FPGAs -> radiation-tolerant programmable logic -> space-grade semiconductors, and derives its architecture from the commercial Microsemi (Actel) Axcelerator family. Key features include nonvolatile antifuse programming technology, which is live-at-power-up and requires no configuration PROM, single-chip form factor, embedded SRAM blocks totaling up to 540 kbits with optional EDAC protection, segmentable clocks, and chip-wide highway routing. The DL variant integrates dedicated DSP mathblocks, offloading multiply-accumulate operations from general-purpose logic and dramatically improving FFT and FIR filter throughput per watt. Technically, the device is fabricated in CMOS and operates from a nominal 1.5V core supply (1.425V to 1.575V range per Microchip data). Radiation performance includes functional operation to 300 krad (Si) total ionizing dose and 200 krad (Si) for related parameters, per the RTAX-S/SL and RTAX-DSP datasheet. The hermetic ceramic metal-sealed CQFP package supports the outgassing and reliability requirements of spaceflight assembly. Typical applications include satellite payload processing, onboard image and signal processing, spacecraft bus controllers, and telemetry/telecommand systems - anywhere high DSP throughput must coexist with radiation tolerance and single-chip simplicity. A critical design consideration is that antifuse FPGAs are one-time programmable: any logic change requires a physical board replacement, so extensive pre-flight simulation and in-orbit flexibility trade-offs must be evaluated against SRAM-based alternatives.

RTAX2000DL-CQ352E - 2M-Gate Rad-Tolerant FPGA CQFP-352 | Microchip
The Microchip Technology (Actel/Microsemi) RTAX2000DL-CQ352E is a 2,000,000-system-gate radiation-tolerant antifuse FPGA from the RTAX-DSP/RTAX-SL family, organized as 19,712 Configurable Logic Blocks (CLBs) and packaged in a 352-terminal ceramic quad flat pack (CQFP-352) with a square, metal-sealed cofired ceramic body measuring 48 mm x 48 mm on a 0.50 mm terminal pitch. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the heavy-ion and proton environments of orbital and deep-space missions. Within the space-electronics hierarchy (semiconductor -> programmable logic -> FPGA -> radiation-tolerant FPGA), the RTAX family sits in the one-time-programmable antifuse class, distinct from SRAM-based FPGAs: configuration data is stored physically in antifuse elements, so the device is live-at-power-up with no external configuration ROM required and no configuration upset mechanism. Key features include the 2M-gate fabric with embedded SRAM blocks featuring built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and 166 input and 166 output user terminals in the CQ352 package. The D-speed grade ordering option balances logic performance against total ionizing dose and single-event-effect performance for typical LEO and MEO missions. Architecturally, RTAX-DSP devices derive from the commercial Microsemi Axcelerator family, retaining its cluster-based logic structure while qualifying the fabric for space-flight doses. The antifuse OneTime programmability also reduces SEU-sensitive configuration overhead compared to SRAM FPGAs, and simplifies board design with a true single-chip form factor. Typical applications include satellite payload data processing, spacecraft avionics and command/data-handling units, telemetry encoders, and sensor-interface digital signal processing on orbital platforms where low power, radiation tolerance, and instant-on operation are mandatory. A key design consideration: antifuse FPGAs are one-time programmable, so the design must be fully verified in simulation and via the footprint-compatible Axcelerator prototyping flow (adaptor-board methodology) before committing hardware; pinout changes after fabrication are impossible.

It operates from a nominal 1.5V core supply (1.425V to 1.575V) across a military/space temperature range of -55C to +125C, fabricated on a 0.15um CMOS process with performance up to 649 MHz. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the single-event effects and total ionizing dose found in space-flight radiation environments. Within the power hierarchy, it belongs to the programmable logic device (PLD) family: FPGA -> radiation-tolerant FPGA -> space-grade programmable logic. Unlike SRAM FPGAs that require external configuration, RTAX-S devices are one-time programmable anti-fuse based, providing true single-chip, live-at-power-up operation that eliminates the need for a configuration PROM and reduces boot-time vulnerability. Key features include SEU-hardened registers that eliminate the need for Triple-Module Redundancy (TMR), immunity to single-event upsets to a specified LET threshold, and a quoted SEU rate of less than 10-10 errors per bit-day, plus embedded SRAM with built-in FIFO control logic, segmentable clock resources, and chip-wide highway routing inherited from the commercial Axcelerator family architecture. Technically, the RTAX2000S derives from the Axcelerator fabric with radiation hardening by design. The anti-fuse interconnect is inherently immune to configuration upsets, so only user registers require SEU hardening. Embedded SRAM blocks support FIFO and dual-port operation for on-board data processing and payload buffering. Roughly 250,000 equivalent ASIC gates of embedded resources supplement the programmable fabric in the RTAX-DSP oriented members. Typical applications include satellite payload data processing, spacecraft command and data handling (C&DH), telemetry encoder/decoder logic, and instrument control in low-Earth-orbit and deep-space missions where reprogrammability is not required and radiation robustness is paramount. A key design consideration is that the CGA-624 ceramic package requires a compatible land pattern and column-grid socket strategy; verify thermal resistance per the JEDEC JESD51 simulation conditions cited in the manufacturer datasheet.

RTAX2000S-1CQ352PROTO - Rad-Tolerant FPGA 2M Gates | Microchip
The Microchip Technology RTAX2000S-1CQ352PROTO is a radiation-tolerant FPGA from the RTAX2000S family, providing 21,504 configurable logic blocks (CLBs), approximately 2 million equivalent system gates, and a CQFP352 ceramic quad flat pack package in a PROTO (prototyping/engineering) device designation with commercial temperature grade and -1 speed grade. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive and operate reliably in space-flight radiation environments, where total ionizing dose (TID) and single-event effects would degrade or destroy standard commercial silicon. Within the power-management hierarchy of avionics electronics, these devices occupy the top reliability tier above standard and military-grade FPGAs, sitting in the broader taxonomy of programmable logic: FPGA -> radiation-tolerant FPGA -> space-grade programmable logic IC. Key differentiating features of the RTAX-S family include low-power operation, a true single-chip form factor (no configuration PROM required at startup), and live-at-power-up behavior enabled by antifuse programmability. Unlike SRAM-based FPGAs, the antifuse architecture is one-time programmable, so configuration data is inherently immune to configuration upsets and the device is functional immediately when power is applied - a critical property for spacecraft that cannot tolerate a configuration reload cycle. Architecturally, the RTAX2000S is fabricated in a CMOS process and organizes its ~2 million gates across logic modules, embedded SRAM blocks, and I/O clusters. Designers implement radiation-hardening-by-design techniques at the system level, typically combining the RTAX-S fabric with external triple-module-redundancy (TMR) schemes supported by Microchip's Libero design suite and Hi-Rel mitigation flows. Typical applications include satellite payload processing, spacecraft bus control, telemetry and telecommand interfaces, and launch-vehicle avionics - anywhere complex logic must operate for years in orbit. The PROTO suffix denotes engineering/prototype hardware intended for design development and system validation rather than flight lots. A key design consideration: PROTO devices must not be substituted for qualified flight units in final flight hardware; flight programs should transition to the corresponding V (flight) suffix part. This page consolidates verified specifications, drop-in family alternatives, and procurement guidance beyond what distributor listings typically show.

A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the single-event upset (SEU) and total ionizing dose (TID) environment of space flight. Within the power-management hierarchy of a spacecraft avionics stack, the FPGA sits as the central programmable logic element between the on-board computer and mission payloads, and the RTAX-S family is a radiation-tolerant antifuse (one-time programmable, OTP) member of the broader FPGA/programmable logic taxonomy. Key features include SEU-hardened registers that eliminate the need for triple-module redundancy (TMR) on flip-flops, live-at-power-up operation due to the non-volatile antifuse fabric, true single-chip form factor without external configuration memory, and low static power consumption. The PROTO suffix denotes a prototyping device intended for design validation before flight-unit programming. Architecturally, the RTAX2000S uses CMOS antifuse technology with an R-cell/C-cell logic fabric and supports clock speeds up to approximately 350 MHz. I/O standards include single-ended and differential pairs via dedicated P/N pin pairs, and embedded SRAM blocks support FIFO and dual-port memory functions. Typical applications include satellite payload data processing, spacecraft telemetry and command interfaces, attitude control electronics, and radiation-tolerant glue logic replacing multiple ASIC functions. Design consideration: per Microchip application note AC170, prototyping must be done with the RTAX-S design flow in Libero SoC converted to an Axcelerator device; reverse flow is not permitted, so final timing closure must always be verified on the RTAX-S target. This page adds value beyond the datasheet with drop-in alternatives, cross-reference data, and distributor sourcing information synthesized from live web data.
RTAX2000S-CQ256PROTO - 2M-Gate Rad-Tolerant FPGA Prototype | Microchip

Built on CMOS anti-fuse architecture, it supports system frequencies up to 350 MHz and provides 136 user input/output pins, with functional characteristics matching the flight-unit RTAX2000S in a non-hermetic package. A radiation-tolerant FPGA (Field Programmable Gate Array) is a programmable logic device engineered to survive the ionizing radiation environments of space flight, including total ionizing dose (TID), single-event upset (SEU), and single-event latchup (SEL). Within the power hierarchy of spacecraft electronics, the RTAX-S family sits alongside rad-hard processors and memory as core onboard data-processing silicon, using anti-fuse programmable interconnect that is programmed once and remains stable under radiation. Key features of the RTAX2000S-CQ256PROTO include low-power consumption, true single-chip form factor, and live-at-power-up (LAPU) operation, which eliminates the need for an external configuration device. The PROTO variant shares the same functional characteristics as the space flight unit but ships in a non-hermetic package at a fraction of the cost, specifically for functional verification before committing to flight parts. Architecturally, the RTAX-S/SL family uses Microchip's Axcelerator-derived logic fabric with a sea-of-modules architecture combining C-cells, R-cells, and embedded SRAM/dedicated FIFO blocks, enabling high performance at densities up to four million equivalent system gates for space-based applications. Typical applications include satellite on-board data handling, spacecraft payload processing, telemetry and telecommand interfaces, and reprogrammable prototyping of RTAX-S flight designs. Designers often pair the PROTO device with Aldec prototyping adaptors that map ProASIC3E flash technology onto the CQ256 footprint for iterative functional verification. A key design consideration is that PROTO devices are non-hermetic and not radiation-screened, so they must never be flown; they exist solely for de-risking the flight design. Timing closure performed on PROTO silicon should be re-verified against flight-grade specifications.

The defining feature of the RTAX2000S is its antifuse programming technology. Unlike SRAM-based FPGAs, the antifuse configuration is non-volatile and inherently radiation-immune: the device is live at power-up with no configuration time, no external configuration PROM, and no configuration-bit upset risk. This gives the RTAX2000S a true single-chip form factor, reducing board area, mass, and system complexity in orbit. The device targets high-reliability space designs with low static power consumption, an important consideration for solar- and battery-powered spacecraft. Logic density of 2 million system gates accommodates payload processing, bus interfaces, telemetry formatting, and glueless integration of boards that previously required multiple ASICs or discrete devices.

The Microchip Technology RTAX2000SL-1LG1152V is a radiation-tolerant, antifuse-based FPGA from the RTAX-S/SL family, delivering an equivalent gate count of 2,000,000 with 32,256 logic cells and 21,504 configurable logic blocks (CLBs) in a 1152-pin ceramic column grid array (CG1152) package. The -1 speed grade and V (flight) quality suffix mark it as a space-flight-grade device intended for orbital and deep-space missions. A radiation-tolerant FPGA is a programmable logic device qualified to survive the total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SET/SEU) environment of spaceflight, sitting within the hierarchy: FPGA -> programmable logic device -> digital IC -> space-grade semiconductor. Unlike SRAM-based FPGAs, the RTAX-S/SL family uses antifuse programmable interconnect, which is one-time programmable and therefore configuration-data immune to SEU effects, enabling live-at-power-up operation without an external configuration flash. Key features include true single-chip form factor (no boot PROM required), low static power consumption critical for power-constrained spacecraft, and the SL process refinement of the RTAX-S architecture. According to the Microchip RTAX-S/SL datasheet, the family is the FPGA of choice for space designers requiring high logic capacity with radiation performance validated for flight programs. Architecturally, the device combines the Actel/Microsemi Axcelerator-derived logic fabric with radiation-hardened interconnect, supporting synchronous and asynchronous designs implemented through Microchip/Libero design flow. The 1152-pin CGA package provides the I/O count needed for payloads, buses, and telemetry interfaces in high-density avionics. Typical applications include satellite payload data processing, spacecraft avionics and attitude-control logic, telecommand/telemetry interfaces, and radiation-hardened glue logic replacing multiple ASICs or MIL-STD parts. The RTAX2000SL-1LG1152V fits missions where high gate count, configuration SEU immunity, and deterministic power-up behavior outweigh reprogrammability. Design consideration: because antifuse FPGAs are one-time programmable, full design verification and the vendor's prototyping methodology (RTAX2000SL-1LG1152PROTO plus adaptor boards and EDIF netlist conversion) must be completed before programming flight devices.

RTAX2000SL-1LG624V - 2M-Gate Rad-Tolerant FPGA | Microchip
The Microchip Technology RTAX2000SL-1LG624V is a radiation-tolerant FPGA offering approximately 2,000,000 equivalent gates, 21,504 CLBs, and 32,256 logic cells in a 624-terminal ceramic CGA624 package, qualified for the full military temperature range of -55C to +125C with a nominal 1.5V core supply. A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the heavy-ion and proton environments of spaceflight, where commercial silicon would suffer destructive latch-up or unacceptable configuration upsets. The RTAX-S/SL family sits within the broader hierarchy: FPGA -> programmable logic IC -> space-grade semiconductor, and serves as the flight-compute backbone for satellites, rovers, and planetary probes. Key features of this device include the SL (super low-power) process variant, live-at-power-up operation enabled by its non-volatile anti-fuse programmable fabric, and a true single-chip form factor that eliminates external configuration storage - a critical reliability advantage in orbit where configuration memories are vulnerable to single-event upsets. Low static power consumption preserves the tight spacecraft power budget. Architecturally, the RTAX-S/SL fabric combines configurable logic modules, embedded SRAM blocks, and hard-wired FIFOs, with ample parallel and serial I/O for payload interfaces. The die also supports roughly 250,000 ASIC gates of additional capability per the SL density roadmap. Programming is one-time (anti-fuse), so design freeze and qualification flow mirror an ASIC while retaining FPGA development schedules. Typical applications include satellite payload data processing, telemetry and telecommand controllers, sensor-interface engines for scientific instruments, and bus avionics for LEO, GEO, and deep-space missions. Design consideration: because the fabric is one-time programmable, perform full timing simulation and radiation-lot qualification before commit; plan for the ceramic column-grid-array solder assembly early.

Typical applications include satellite payload processing and telemetry formatting, spacecraft bus controllers, radiation-tolerant glue logic that replaces multiple ASICs, and instrument control for science missions. The 624-pin CCGA solder-column package supports reliable board-level attachment for launch-vibration and thermal-cycling environments. Design consideration: as a one-time-programmable (OTP) anti-fuse device, the RTAX2000SL requires rigorous pre-flight design verification; use the Aldec/Microchip flash-based ProASIC3E prototyping adaptor to iterate designs before committing flight hardware.

Key features include 2M system gates of CMOS anti-fuse fabric, 21,504 CLBs, embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and carry logic for arithmetic. Live-at-power-up operation means the configured design is functional immediately when power is applied - a critical property for spacecraft that cannot tolerate configuration boot delays or configuration-memory upsets. Technically, the RTAX2000SL is one-time programmable (OTP): the anti-fuse interconnect is permanently set during programming, which eliminates configuration memory SEU vulnerability, a key advantage over SRAM-based FPGAs in orbit. The SL variant adds SEU-hardened flip-flop enhancements over the base RTAX2000S. The family scales to four million equivalent system gates, and designs can be prototyped on the equivalent commercial Axcelerator devices using a documented migration flow, or emulated with Aldec ACT-H3Ki-CG624 adaptors that mimic the CG624 footprint. Typical applications include satellite payload data processing, spacecraft bus control and telemetry, communication transponder digital baseband, and space science instrument interface logic - anywhere reprogrammability at the design stage plus radiation tolerance in flight are required together. A key design consideration: the CGA-624 ceramic package requires a matching 624-pad PCB footprint and column-grid soldering process; verify board layout against the manufacturer datasheet package drawing before release.
