RTAX2000S-1CGS624EV Descripción general
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.

Aplicaciones típicas
RTAX2000S-1CGS624EV es adecuado para 6 aplicacións: Satellite Payload Data Processing, Spacecraft Command and Data Handling (C&DH), Telemetry Encoder/Decoder and Downlink Formatting, Instrument Control for Space Science Missions, Launch Vehicle Avionics and Flight Logic, Radiation Test and Engineering Model Development.
Satellite Payload Data Processing
The RTAX2000S-1CGS624EV fits satellite payload processing because its 2,000,000 system gates and 21,504 CLBs provide enough fabric for on-board image compression, filtering, and protocol adaptation, while embedded SRAM with built-in FIFO control handles high-rate data streaming without external memory. Its SEU-hardened registers deliver an SEU rate below 10-10 errors/bit-day without Triple-Module Redundancy, preserving gate capacity for payload functions. In the signal chain, the FPGA typically sits between sensor front-ends and downlink formatters, clocked from segmentable on-chip clock resources up to 649 MHz capability. Because the anti-fuse fabric is live at power-up, payload start-up latency is minimal compared to SRAM FPGA solutions that must load configuration from external memories in orbit.
Recomendado
Spacecraft Command and Data Handling (C&DH)
For C&DH modules, the RTAX2000S-1CGS624EV provides glue logic, bus interfacing, telemetry formatting, and housekeeping functions on a single rad-tolerant chip. The single-chip, live-at-power-up anti-fuse architecture removes the external configuration PROM that is a common single point of failure in space avionics, improving overall reliability. The 624-pin CCGA package supplies abundant I/O for MIL-STD-style bus and discrete interfaces, and the -55C to +125C rating covers worst-case thermal environments in unheated equipment bays. Designers typically combine the FPGA with a rad-hardened microcontroller, using the FPGA for time-critical framing and memory-mapped register decoding while the processor handles higher-layer telemetry management, keeping critical paths within the deterministic FPGA fabric.
Recomendado
Telemetry Encoder/Decoder and Downlink Formatting
Downlink chains benefit from the RTAX2000S-1CGS624EV's deterministic anti-fuse timing and 649 MHz fabric capability, which support CCSDS-style channel coding and framing at high symbol rates. Embedded FIFO-organized SRAM buffers data between the payload source clock domain and the encoder clock domain, while SEU-hardened registers protect protocol state machines without TMR overhead. The 21,504 CLBs accommodate parallelizer, scrambler, and Reed-Solomon style blocks with margin for redundancy. Placement between the payload router and the modulator keeps switching activity localized; the 1.5V nominal core supply (1.425V-1.575V) limits dynamic power, an important consideration for power-constrained smallsat buses relying on limited solar array margin during eclipse operations.
Recomendado
Instrument Control for Space Science Missions
Science instruments on LEO and deep-space missions use the RTAX2000S-1CGS624EV for detector timing generation, ADC interface sequencing, and autonomous event handling. The -55C to +125C operating range and hermetic ceramic CCGA-624 package withstand launch vibration and cryogenically cold instrument bays, while the anti-fuse interconnect is immune to configuration upsets, so detector timing patterns cannot be corrupted in flight. SEU-hardened registers keep exposure-control counters valid at the datasheet LET threshold. Because the device is live at power-up, instruments begin acquiring data immediately after turn-on without a configuration load interval, which matters for time-critical observation windows such as planetary flybys and occultation measurements where every second of uptime is scientifically valuable.

Launch Vehicle Avionics and Flight Logic
Launch vehicles demand logic that is operational within milliseconds of power application and immune to vibration-induced configuration loss; the RTAX2000S-1CGS624EV meets both needs with its single-chip anti-fuse architecture rated to +125C and -55C. Typical roles include stage-separation sequencing, safe-and-arm interface monitoring, and telemetry multiplexing, where SEU-hardened registers protect state machines from single-event upsets during passes through the South Atlantic Anomaly or during solar particle events. The 2M-gate fabric implements multiple redundant channels of critical logic with voting, and the extensive 624-pin I/O count accommodates discrete pyrotechnic channel interfaces, analog monitor digitization support, and redundant MIL-STD-1553-style bus interfaces on one rad-tolerant device.
Recomendado
Radiation Test and Engineering Model Development
Programs building engineering models (EM) and radiation test vehicles use the RTAX2000S-1CGS624EV alongside commercial-temperature family prototypes to de-risk flight designs. Logic is developed in the Microchip/Libero tool flow on commercial ProASIC or Axcelerator-based platforms, then targeted to the RTAX-S fabric; using the same die (21504 CLBs, 2M gates) for EM and flight units minimizes re-verification. Test teams populate CCGA-624 evaluation boards for heavy-ion and proton testing, using the datasheet LET threshold and the sub-10-10 errors/bit-day SEU rate as acceptance criteria. Traceable ordering suffixes (E vs V flow) let programs separate engineering screening from flight lot certification while keeping a common footprint across all build phases.

Notas de diseño
The 624-pin ceramic column grid array uses column terminations rather than solder balls; verify your PCB land pattern and reflow profile against the manufacturer CCGA assembly application guidance. Distributor data lists a 1.270 mm terminal pitch for the CGA624 package, requiring controlled warp ceramic handling and X-ray inspection post-assembly. Estimate: allow expansion joints or under-stiffener strategies when mounting on FR-4 to relieve CTE mismatch between the ceramic package and organic board over thermal cycling from -55C to +125C.
Supply the core at 1.5 V nominal within the 1.425 V to 1.575 V window per Microchip USA listing; use a rad-tolerant or board-level tolerant point-of-load regulator with sequencing appropriate to the RTAX-S power-up requirements described in the manufacturer datasheet. Because anti-fuse FPGAs draw no configuration current at power-up, inrush is governed mainly by decoupling capacitor charging; size bulk capacitance for the bus voltage droop budget. Verify I/O bank supply voltage values in the official datasheet before finalizing the power tree.
Ordering-code suffixes matter in space programs: CG624 vs CGS624 package codings and E vs V flow options indicate different screening, and some family members are explicitly NOT pin compatible in certain packages (the datasheet states RTAX2000S/SL and RTAX2000D/DL are not pin compatible in the CQ352 package; RTAX4000 overhang differs slightly). Confirm pin compatibility for your exact package code before reusing a layout. Also do not assume speed-grade interchangeability - the -1 grade timing files differ from standard grade in timing-driven place-and-route.
