RTAX1000SL-CGS624B Présentation
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environment of space flight, including total ionizing dose (TID) and single-event effects (SEE). Unlike commercial FPGAs, rad-tolerant FPGAs sit at the top of the programmable logic hierarchy (FPGA -> programmable logic IC -> digital IC -> semiconductor) and are qualified for satellite, planetary probe, and launch-vehicle electronics where replacement after deployment is impossible.
Key features include the anti-fuse-based RTAX-SL architecture derived from the commercial Axcelerator family, which provides live-at-power-up operation with no configuration device required. The embedded SRAM blocks include built-in FIFO control logic, and the fabric offers segmentable clocks and chip-wide highway routing for large system designs. Speed-grade B devices support system clock rates up to 581 MHz per family datasheets, with a 1.5V core supply.
The RTAX-SL fabric integrates embedded SRAM and bus-capable routing in a true single-chip form factor with low power consumption, making it suitable for payloads that must survive launch vibration and multi-year orbital missions. Design migration to RTAX-DSP variants is supported through the same development flow.
Typical applications include satellite payload data processing, spacecraft bus control, telemetry and telecommand (TT&C) interfaces, and instrument control in deep-space science missions.
A key design consideration: use Microchip Libero SoC with the RTAX-S prototyping methodology (footprint-compatible adaptor board plus EDIF netlist and pinout converter) to validate designs on commercial ProASIC/AX equivalents before committing to flight units.

Applications typiques
RTAX1000SL-CGS624B convient pour 6 applications: Satellite Payload Data Processing, Spacecraft Bus Control, Telemetry, Tracking & Command (TT&C), Deep-Space Science Instrument Control, Launch Vehicle Avionics, Earth Observation Imaging Chains.
Satellite Payload Data Processing
The RTAX1000SL-CGS624B fits payload processing chains that need 1M gates of reprogrammable logic plus embedded SRAM FIFOs in a single rad-tolerant chip. Its anti-fuse fabric is live at power-up, eliminating configuration-flash SEE concerns that plague SRAM FPGAs in orbit, and the 12,096 CLBs implement channelizers, FEC encoders, and framing engines. Placed between ADC/FPGA front ends and downlink modulators, its embedded SRAM with built-in FIFO control buffers high-rate science data without external memory, reducing parts count and board-level failure points. The 581 MHz B-grade fabric supports parallel datapaths at 100+ MHz real-world clock rates, and the CCGA-624 package's column interconnect withstands thermal cycling over multi-year LEO missions.

Spacecraft Bus Control
Spacecraft bus controllers demand deterministic, always-on logic that survives total ionizing dose over mission life, which is exactly the RTAX-SL anti-fuse value proposition. The RTAX1000SL-CGS624B implements reaction-wheel interfaces, mode-state machines, and housekeeping telemetry with live-at-power-up operation so the FPGA is functional the instant the spacecraft separates from the launch vehicle - no configuration load delay. Its segmentable clocks and chip-wide highway routing support multiple independent functional domains (power, AOCS, TT&C) within one device. Low static power from the 1.5V core preserves battery energy during eclipse operations, and the CCGA-624 ceramic package provides hermetic environmental protection for vacuum operation.
Recommandé
Telemetry, Tracking & Command (TT&C)
TT&C subsystems benefit from the RTAX1000SL-CGS624B's combination of 1M gates and deterministic anti-fuse timing with no configuration-upset risk from single-event effects. Designers implement CCSDS framing, convolutional and Reed-Solomon encoders/decoders, and command decoders in the 12,096-CLB fabric, while embedded SRAM blocks with FIFO control handle rate buffering between the baseband and RF sections. Because the device is configured at manufacture (one-time programmable), TT&C logic cannot be corrupted in flight - a critical reliability property for the link that commands the spacecraft. The B speed grade's 581 MHz ceiling comfortably covers typical TT&C symbol rates with parallelism margin.

Deep-Space Science Instrument Control
Deep-space instruments such as spectrometers and imagers require logic that tolerates high TID behind minimal shielding, and the RTAX1000SL-CGS624B addresses this with its rad-tolerant 0.15 um CMOS anti-fuse process. Instrument sequencers, ADC interface logic, and on-board compression engines fit within the 1M-gate / 125,000 ASIC-gate capacity, with embedded SRAM FIFOs absorbing burst data from sensor arrays. True single-chip operation (no external configuration device) reduces the parts exposed to the radiation environment. Engineers should budget SEU mitigation via triple-module redundancy in the fabric, and use the Microchip prototyping methodology on commercial Axcelerator parts before committing flight units.
Recommandé
Launch Vehicle Avionics
Launch-vehicle flight computers and stage controllers use the RTAX1000SL-CGS624B where short but severe missions demand guaranteed live-at-power-up behavior and vibration-tolerant column-grid packaging. The CCGA-624 ceramic package's column interconnect resists mechanical shock during stage separation better than fine-pitch commercial BGAs, and the anti-fuse fabric needs no boot sequence during the seconds-critical launch timeline. The 1M-gate fabric implements GN&C glue logic, redundant-voter circuits, and telemetry multiplexers, while segmentable clocks let designers partition safety-critical and non-critical functions with independent timing domains. DLA-qualified variants of the RTAX1000SL family exist under Mil-Prf-38535 Class V per Microchip's DLA cross-reference guide.
Recommandé
Earth Observation Imaging Chains
Earth-observation satellites route high-rate imager data through the RTAX1000SL-CGS624B, which provides enough 12,096-CLB capacity for CCD/CMOS sensor interface, defect correction, and lossless pre-compression in one rad-tolerant chip. Embedded SRAM with FIFO control logic buffers line data between the sensor clock domain and the mass-memory downlink domain without external FIFO ICs. The device's low power consumption matters because imaging payloads are power-budget-critical in orbit, and live-at-power-up anti-fuse configuration ensures the imager is ready at first acquisition. For higher-resolution instruments, the same-package RTAX2000SL-CGS624B doubles logic capacity with zero board redesign.

Notes de conception
The CGS624 CCGA uses solder columns rather than solder balls, so the land pattern must be designed for column pitch with adequate fillet volume; follow the RTAX-S/SL datasheet package mechanical drawing. Columns mechanically decouple the ceramic substrate from PCB thermal-expansion mismatch, which is essential across the large temperature swings of orbital missions. Avoid routing high-speed signals directly under the package center without a ground plane, and verify board warpage specs meet the ceramic package flatness requirement before reflow profiling.
RTAX-S devices are one-time programmable anti-fuse FPGAs - there is no rework path after programming. Complete full timing closure, functional verification, and pin assignment sign-off in Microchip Libero SoC before sending flight units to programming. Use the manufacturer's prototyping methodology (footprint-compatible adaptor board on commercial Axcelerator parts plus EDIF netlist and pinout conversion) to shake out design bugs on cheap commercial silicon first, per the application note 'Prototyping for RTAX-S and RTAX-SL Devices'.
Estimate: budget the 1.5V core supply per the RTAX-S/SL datasheet power calculator with your actual toggle rates, since fabric power scales with switching activity and the 1M-gate fabric can draw substantial current at high utilization. Provide independent clean rails for core and I/O banks with bulk plus 0.1uF decoupling at each supply pin group. Ensure power-up ramp meets datasheet monotonicity requirements - anti-fuse devices must be live and configured correctly at first power application.
With 624 I/O available in the CGS624 package, group I/O banks by voltage standard and keep simultaneously switching outputs distributed across banks to limit ground bounce on the ceramic substrate. Simulate flight harness-driven lines for reflection and crosstalk, and reserve spare pins for mitigated (TMR-replicated) signals in SEU-critical paths. Match trace lengths within source-synchronous buses such as ADC or DDR-style interfaces to the datasheet setup/hold budgets for the B speed grade.
