A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SEU) environments of orbital and deep-space missions. Within the power hierarchy, it sits in the programmable logic family alongside the commercial Axcelerator, ProASIC3, and Igloo devices, bridging the gap between standard COTS FPGAs and fully radiation-hardened ASICs. RTAX-S/SL devices are live-at-power-up because the anti-fuse configuration is permanent and needs no configuration flash or external boot device.
Key features include up to four million equivalent system gates across the family, embedded SRAM blocks with built-in FIFO control logic, segmentable clock circuitry, and chip-wide highway routing. The RTAX2000SL provides 21,504 CLBs and supports an additional 250,000 ASIC gates for hardening-by-design flows when a mission later migrates to an RTAX-H or ASIC implementation. Low static power consumption and a true single-chip form factor reduce board area, mass, and power budgets, which are critical constraints on satellites and planetary probes.
Architecturally, the device is based on the commercial Axcelerator fabric, giving designers a proven sea-of-modules structure with embedded FIFO and dual-port SRAM capability. Because the anti-fuse interconnect is programmed once, designs are immune to configuration upsets, and only user flip-flops require SEU mitigation techniques such as triple modular redundancy (TMR).
Typical applications include satellite payload data processing, spacecraft bus controllers, telemetry and telecommand interfaces, and sensor front-end digital signal conditioning for LEO, MEO, and GEO missions. The Aldec RTAX prototyping adaptor allows flash-based ProASIC3E prototyping before committing to one-time programming.
A key design consideration is that the OTP fabric cannot be reprogrammed in flight or on the board after programming, so functional coverage and radiation test planning must be complete before lot commit.

典型應用
RTAX2000SL-1CGS624EV 適用於 6 應用s: Satellite Payload Data Processing, Spacecraft Bus Controller Logic, Telemetry and Telecommand Interfaces, Sensor Front-End Digital Signal Conditioning, ASIC Prototyping and Heritage Migration, LEO Smallsat and Rideshare Avionics.
Satellite Payload Data Processing
The RTAX2000SL-1CGS624EV fits payload data processing chains where 2,000,000 system gates and 32,256 logic cells absorb framing, compression, and channel coding functions. Its embedded SRAM blocks with built-in FIFO control logic buffer high-rate sensor streams without external memory, while the anti-fuse OTP fabric is immune to configuration upsets in orbit. Placed between payload sensors and downlink modulators, the device runs SEU-mitigated (TMR-protected) user logic; the one-time-programmed interconnect means only flip-flops need mitigation, cutting overhead versus SRAM-based FPGAs. The CGS624 ceramic package provides the terminal count needed for wide parallel data buses in a space-qualified, thermally robust body.

Spacecraft Bus Controller Logic
For spacecraft bus control, the RTAX2000SL-1CGS624EV implements telecommand decoders, telemetry formatters, and mode-control state machines that must be live at power-up immediately after launch-separator deployment. The anti-fuse configuration loads nothing, so the FPGA is functional the instant rails settle - a defining RTAX-S/SL advantage cited by Microchip for flight systems. Segmentable clock resources support multiple independent bus interface domains on one chip, consolidating functions that would otherwise need several devices, reducing board mass and parts count. The 624-terminal CGS624 package offers ample I/O for MIL-STD-1553-style interfaces, discrete commands, and redundant power switching logic.
推薦
Telemetry and Telecommand Interfaces
Telemetry/telecommand subsystems benefit from the RTAX2000SL-1CGS624EV's combination of deterministic OTP fabric and 21,504 CLBs of routing capacity for CCSDS framing, convolutional or Reed-Solomon encoding, and time-tagging. Embedded FIFO-controlled SRAM smooths burst data between the formatter and downlink modulator. Because the device is radiation-tolerant rather than merely COTS, it addresses TID and SEE environments typical of LEO-to-GEO missions; designers apply TMR on command-critical registers while the permanent interconnect eliminates single-event configuration upset risk entirely. The -1 speed grade supplies ample timing margin for typical TT&C data rates well below the fabric's maximum.
推薦
Sensor Front-End Digital Signal Conditioning
Imaging and science instrument front ends use the RTAX2000SL-1CGS624EV to perform deserialization, gain/offset correction, and packetization of high-rate detector data. The 32,256 logic cells and embedded dual-port-capable SRAM implement line buffers and accumulation pipelines directly, avoiding external memory that adds mass and failure modes. According to Microchip, RTAX-S/SL devices were derived from the commercial Axcelerator family, giving designers proven high-speed fabric for megapixel sensor interfaces while retaining radiation tolerance for the mission environment. The wide 624-terminal package supports the many parallel LVDS-style and single-ended detector interfaces typical of space cameras and spectrometers.

ASIC Prototyping and Heritage Migration
Programs planning a hardened ASIC migration use the RTAX2000SL-1CGS624EV as the flight-proven prototype: Microchip documents 250,000 additional ASIC gates available, and the RTAX fabric is the direct precursor to RTAX-H and hardened flows, allowing RTL reuse. The Aldec RTAX prototyping adaptor pairs the design flow with flash-based ProASIC3E devices so engineers iterate firmware freely before committing the OTP flight part - eliminating costly re-spins of one-time-programmable silicon. With 2,000,000 gates, the RTAX2000SL hosts realistic design sizes during validation, and its heritage equivalence to the ESCC-listed RTAX2000S smooths qualification paperwork for ESA-aligned programs.
推薦
LEO Smallsat and Rideshare Avionics
LEO smallsat and rideshare missions choose the RTAX2000SL-1CGS624EV when avionics need single-chip, live-at-power-up programmable logic with meaningful density (2M gates) and low static power. The OTP anti-fuse fabric removes the mass and reliability cost of a configuration flash, and configuration-upset immunity simplifies SEU analysis to user registers only. Designers should weigh the CGS624 ceramic package mass against smaller RTAX2000SL CQ256 or CQ352 variants when board area is constrained. For rideshare missions with modest TID exposure, the radiation-tolerant rating provides margin at lower cost than rad-hard ASIC alternatives, with flight heritage documentation available from Microchip.

設計說明
The RTAX2000SL is one-time programmable: once the anti-fuse array is programmed, the configuration is permanent and cannot be corrected in flight or on the bench. Freeze RTL, complete functional coverage, and finalize TMR strategy before submitting the programming file. Use the Aldec flash-based ProASIC3E prototyping adaptor to iterate designs safely prior to committing flight silicon, and use PROTO-flow parts (e.g., RTAX2000S-1CG624PROTO) for engineering lots - never PROTO parts on flight boards.
RTAX-S/SL devices are promoted by Microchip for low-power consumption and true single-chip, live-at-power-up operation - no external configuration flash draws current at boot. Budget static and dynamic power using the Microchip Libero SoC power calculator with the -1 speed grade characterization, and verify I/O bank currents against the CGS624 package limits. Because exact core/IO voltage values should come from the current datasheet revision, always cross-check supply rails against the latest rtaxs datasheet before board release.
With 624 terminals on a ceramic column grid array, PCB breakout requires via-in-pad or doghouse fanout on high-layer-count flight boards. Follow the RTAX-S/SL datasheet package chapter for terminal assignment, power/ground pairing, and JTAG access. The chip-wide highway and segmentable clock structure allows multiple clock domains - keep domain crossings registered and apply triple modular redundancy to control and state registers for single-event upset mitigation, since only the anti-fuse interconnect is inherently upset-immune.
