Typical Applications
RTAX2000SL-1CGS624EV is suitable for 6 applications: 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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.

Key Differentiators
- Enhanced EV screening flow for space programs (vs RTAX2000SL-1CGS624V)
- -1 speed grade timing margin (vs RTAX2000SL-CGS624E)
- Documented heritage equivalence to ESCC-listed part (vs RTAX2000S-1CG624PROTO)
Design Notes
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.
Compliance Information
No compliance data stated in verified web data as of 2026-09-02. Space-grade ceramic devices may carry RoHS exemptions (e.g., leaded ceramic terminations); request official Microchip material declarations for program documentation.
