Typical Applications
RTAX1000SL-1CGS624B is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Command and Data Handling (C&DH), Telemetry Encoding and Decoding, Space-borne Instrumentation and Imaging, Launch Vehicle Avionics, Deep Space Probe Electronics.
Satellite Payload Data Processing
The RTAX1000SL-1CGS624B fits payload processing chains in LEO and GEO satellites where 1,000,000 system gates and 12,096 CLBs provide capacity for compression, encryption, and beamforming pipelines. Its embedded SRAM with built-in FIFO control logic buffers high-rate sensor streams, while the anti-fuse fabric runs live at power-up without external configuration memory - eliminating a single point of failure during deployment. Placed downstream of ADCs or receivers, it performs deterministic processing with segmentable clocks supporting multiple independent processing domains. Unlike SRAM FPGAs, no configuration scrubber is required, reducing board complexity and power draw, a decisive benefit on constrained payload power budgets.
Recommended
Spacecraft Command and Data Handling (C&DH)
For C&DH modules, the RTAX1000SL-1CGS624B implements bus interfaces (MIL-STD-1553-class logic, custom telemetry formats) and housekeeping sequencers that must survive total ionizing dose over a multi-year mission. The radiation-tolerant anti-fuse fabric retains configuration through single-event events, ensuring the command path stays alive after orbital anomalies. With 125,000 additional ASIC gates available, designers can implement glue logic that would otherwise occupy a separate ASIC, reducing part count and qualification burden. The true single-chip form factor simplifies rad-hard board design, and DLA SMD 5962-0422006QUA qualification streamlines flight program acceptance documentation.
Recommended
Telemetry Encoding and Decoding
The RTAX1000SL-1CGS624B suits CCSDS-style telemetry encoders and decoders where deterministic timing and radiation tolerance dominate. The -1 speed grade delivers high fabric performance on CMOS anti-fuse technology, while embedded SRAM blocks implement interleaver and buffer structures with FIFO control included on-chip. Because the fabric is live at power-up, downlink chains begin transmitting immediately after satellite separation events without a configuration sequence - valuable during launch and early operations (LEOP). The 624-ball ceramic CGA package provides hermetic protection and ample user I/O for parallel telemetry interfaces, with chip-wide highway routing easing wide data-path placement across the 1M-gate fabric.
Recommended
Space-borne Instrumentation and Imaging
Scientific instruments and imaging payloads use the RTAX1000SL-1CGS624B to time acquisition, format CCD/CMOS sensor data, and pre-process frames near the focal plane. The low static power of the CMOS anti-fuse fabric matters inside thermally constrained instrument enclosures, and radiation tolerance prevents log-periodic image corruption from configuration upsets. Segmentable clock resources let one FPGA drive multiple sensor readout modes, and the 12,096-CLB capacity absorbs detector-specific interfaces that vary between instrument builds. Designers prototype logic on commercial counterparts, then migrate to flight units with Microchip Libero tooling, preserving timing constraints across the design flow.
Recommended
Launch Vehicle Avionics
Launch vehicle avionics benefit from the RTAX1000SL-1CGS624B's live-at-power-up behavior: flight control and sequencing logic is operational the instant power is applied, with no boot latency that could miss critical event windows. The radiation-tolerant fabric withstands the intense transient radiation belts crossed during ascent, and the hermetic 624-ball ceramic CGA package resists launch vibration and thermal cycling. With 1M system gates, engineers implement redundant two-out-of-three voting logic, fault management, and telemetry formatting in a single device, replacing multiple rad-hard SSI/MSI components and shrinking board area in weight-critical avionics bays.
Recommended
Deep Space Probe Electronics
Deep-space missions impose the harshest radiation budgets, and the SL variant of the RTAX family adds enhanced radiation hardness for these durations. The RTAX1000SL-1CGS624B hosts spacecraft autonomy logic, fault detection/isolation/recovery (FDIR) state machines, and science data compression that must run unattended for a decade or more. Anti-fuse configuration cannot be upset by galactic cosmic rays, removing scrubber design risk far from Earth. The DLA 5962-0422006QUA QML qualification supports program-level reliability audits, and the 125,000 ASIC gates allow custom protocol engines where off-the-shelf interfaces do not exist, consolidating critical electronics into one qualified, single-chip device.

Design Notes
The RTAX-S/SL anti-fuse fabric is one-time programmable - there is no reconfiguration after programming. Freeze the RTL, complete timing closure in Microchip Libero, and run full simulation before releasing flight-lot silicon. A post-programming logic bug cannot be patched in the field, unlike SRAM FPGAs. Budget one spare device per board build for contingency.
RTAX-S/SL devices are prized for low static power because there is no configuration RAM to hold - but dynamic power still scales with clock frequency and toggle rate. Estimate core current using the Microchip power calculator with your actual design; do not size the spacecraft power bus from datasheet typical values alone. Decouple core and I/O rails with low-ESR ceramics placed at the ball-via fanout.
The 624-ball ceramic CGA (column grid array) requires careful PCB pad geometry - use column-array (CGA) land patterns per the Microchip package drawing, not standard BGA pads, because solder columns change reflow behavior. Support the heavy hermetic package with adequate pad retention and inspect with X-ray for column voids after assembly.
With 624 balls of available I/O, allocate return-path reference planes before assigning signals. Keep clock distribution on segmentable clock resources per the RTAX-S/SL architecture, and reserve chip-wide highway routing for wide synchronous buses. Simulate flight-representative stub lengths on ceramic column packages, as their added height slightly alters impedance versus flip-chip BGA peers.
