RTAX2000SL-CQ352V 概要
A radiation-tolerant FPGA is a programmable logic device engineered to survive the ionizing radiation environment of space, including total ionizing dose (TID) and single-event effects (SEE). Within the power-management hierarchy of spacecraft avionics, the RTAX-S/SL family sits between commercial FPGAs and fully rad-hard ASICs, providing programmability with flight-proven reliability based on Microsemi (Actel) commercial Axcelerator architecture.
Key features include 2 million system gates of antifuse-based fabric that is inherently immune to configuration upsets, embedded SRAM blocks with built-in FIFO control logic, segmentable clock circuitry, and chip-wide routing resources. The one-time-programmable antifuse technology means the configuration is live at power-up with no external boot memory, a decisive advantage for launch systems that must operate immediately.
The SL variant uses an enhanced process optimized for lower power consumption in orbit, extending mission life for battery- and solar-constrained spacecraft. The device is fabricated in CMOS technology and qualified per the V-grade flow associated with Class V space-level screening referenced in Microchip DLA documentation (Mil Prf 38535 QML environment for Microchip flight parts).
Typical applications include satellite command and data handling, spacecraft bus controllers, payload data processing, remote sensing instrument interfaces, and launch vehicle avionics. The CQFP-352 hermetic ceramic package with a power/ground-friendly pinout supports socketed or soldered assembly flows common in high-reliability space programs.
Design consideration: because the antifuse fabric is one-time programmable, complete design sign-off should be performed using the Libero SoC design flow and radiation-aware design practices before commit programming; prototypes can be validated on reprogrammable flash-based ProASIC3E devices via the Aldec RTAX prototyping adaptor.

主な用途
RTAX2000SL-CQ352V の用途: 6 件s: Satellite Command and Data Handling, Payload Data Processing, Spacecraft Bus and Platform Control, Launch Vehicle Avionics, Remote Sensing Instrument Interfaces, Radiation-Tolerant Prototype and Test Equipment.
Satellite Command and Data Handling
Spacecraft on-board computers require logic that is functional immediately at power-up and immune to configuration upsets in orbit. The RTAX2000SL-CQ352V provides 2,000,000 equivalent gates and 21,504 CLBs of antifuse fabric that cannot lose its configuration, eliminating the external boot flash single point of failure. The SL low-power process reduces dynamic current, extending battery life during eclipse operations. Embedded SRAM with built-in FIFO control handles telemetry buffering between the processor, mass memory, and downlink chain, while segmentable clocks let designers isolate the telemetry clock domain from the processor bus.
おすすめ
Payload Data Processing
Earth-observation and science payloads generate high-rate sensor data that must be formatted, compressed, and packetized before downlink. The RTAX2000SL-CQ352V supplies 2M system gates of deterministic, single-event-immune logic for this data path, plus embedded SRAM FIFOs for cross-clock-domain buffering. Its CQFP-352 hermetic package supports the screening and traceability demanded by payload electronics, and live-at-power-up configuration ensures the payload controller is ready when the instrument bus energizes. Designers should budget I/O and verify timing at the chosen speed grade in Libero SoC before committing the one-time-programmable antifuses.
おすすめ
Spacecraft Bus and Platform Control
Attitude control, power distribution, and thermal management electronics form the spacecraft bus and benefit from the RTAX2000SL-CQ352V's radiation-tolerant, single-chip architecture. The antifuse fabric holds its configuration through total-ionizing-dose accumulation, and the 21,504-CLB capacity accommodates redundant control state machines, watchdog logic, and housekeeping telemetry interfaces. The 2,000,000-gate device in a 352-pin CQFP offers generous parallel I/O for MIL-STD-style bus interfaces. Segmentable clocking permits independent clock domains for the controller core and redundant sensor channels, simplifying fault isolation during mission operations.
おすすめ
Launch Vehicle Avionics
Launch avionics must be operational within milliseconds of power application during flight, a requirement the RTAX2000SL-CQ352V meets through its live-at-power-up antifuse configuration. There is no configuration-load interval during which flight control logic would be absent, removing a failure mode present in SRAM FPGAs. The -55C to +125C industrial-military temperature span covers pad, ascent, and upper-stage environments, and the hermetic CQFP-352 package resists the mechanical and thermal stress of the launch cycle. With 2M gates, sequencer, telemetry encoder, and safety-interlock logic coexist in one flight-qualified device.
おすすめ
Remote Sensing Instrument Interfaces
Imaging spectrometers, radar front ends, and star trackers interface to spacecraft electronics through glue logic that must tolerate radiation and operate at low power. The RTAX2000SL-CQ352V bridges sensor readout electronics to the payload data formatter with 2 million gates of programmable interface logic, embedded FIFO SRAM for rate adaptation, and chip-wide routing for global resets. The SL process minimizes switching power in continuously powered instrument chains. Because the device is one-time programmable, instrument teams validate the full interface design on reprogrammable ProASIC3E prototyping hardware (e.g., Aldec RTAX adaptor) before committing flight units.
おすすめ
Radiation-Tolerant Prototype and Test Equipment
Ground-support equipment and flight-spare validation benches use PROTO-screened RTAX devices to exercise flight designs without consuming V-grade flight stock. The RTAX2000SL-1CQ352PROTO shares the exact 2M-gate SL die and CQFP-352 footprint as the RTAX2000SL-CQ352V, so the test fixture is electrically identical to the flight unit. Bench engineers can correlate timing measured on PROTO parts with flight-lot units, and reuse the same socket and load board across development, qualification, and acceptance test campaigns, reducing test-equipment cost while preserving signal fidelity at interface pins.

設計ノート
The RTAX2000SL antifuse fabric is one-time programmable: once programmed, the flight unit cannot be corrected. Complete the full design, timing closure, and radiation-aware sign-off in Libero SoC on a reprogrammable ProASIC3E prototyping platform (e.g., Aldec RTAX adaptor) before committing flight devices. Order PROTO-screened parts such as RTAX2000SL-1CQ352PROTO for development builds to preserve scarce V-grade flight stock.
The SL variant is the low-power member of the RTAX-S/SL 2M-gate class; prefer it for solar- and battery-constrained spacecraft. Dynamic power scales with clock domains and toggle rates, so use the segmentable clocks to gate unused regions and enable chip-wide features deliberately. Confirm exact core and I/O supply rails from the RTAX-S/SL datasheet (DS2169) for your speed grade and I/O standard before finalizing the power tree - do not copy rails from commercial Axcelerator documents.
The hermetic CQFP-352 package has leads on four sides; design the land pattern per the RTAX-S/SL datasheet packaging section and support both soldered and socketed assembly flows. Maintain a solid ground plane under the die cavity region, decouple each supply pin pair with local ceramics, and route fine-pitch CQFP leads with controlled impedance for high-speed payload interfaces. Follow manufacturer high-reliability assembly guidance for lead forming if the unit is socketed.
