RTAX4000S-CQ352V 概要
A radiation-tolerant FPGA is a field-programmable gate array 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 electronics, the RTAX-S family sits alongside rad-hard ASICs and flash-based space FPGAs, offering one-time-programmable (OTP) antifuse technology that is immune to configuration upsets - a key advantage over SRAM-based FPGAs in orbit.
Key features include CMOS antifuse architecture that is live-at-power-up with no external configuration device required, true single-chip form factor reducing board area and BOM cost, embedded SRAM blocks with built-in FIFO control logic, segmentable clock conditioning circuitry, and chip-wide highway routing for high fan-out signals.
The RTAX-S/SL and RTAX-DSP family is based on Microsemi's commercial Axcelerator architecture, delivering high performance at densities up to four million equivalent system gates. Device variants such as RTAX4000S and RTAX4000SL share the same silicon and are distinguished by ICCA current screening limits at 125C final electrical test, allowing programs to select the appropriate screening condition.
Typical applications include satellite payload processing, spacecraft bus control, telemetry and telecommand interfaces, and radiation-tolerant glue logic replacing multiple rad-hard ASSPs in low Earth orbit and deep space missions.
Design consideration: the OTP antifuse fabric means programming is final - use the Microchip/Libero design flow with simulation and, where available, flash-based ProASIC3E prototyping adaptors (e.g., Aldec) before committing flight units.

主な用途
RTAX4000S-CQ352V の用途: 6 件s: Satellite Payload Data Processing, Spacecraft Bus Control and Housekeeping, Telemetry and Telecommand (TT&C) Interfaces, Deep Space Mission Avionics, Radiation-Tolerant Glue Logic Integration, Earth Observation Instrument Control.
Satellite Payload Data Processing
The RTAX4000S-CQ352V fits satellite payload processing because its 4,000,000 equivalent gates and 60,480 logic cells provide enough capacity for on-board data compression, formatting, and high-rate interfacing, while its antifuse CMOS fabric is immune to configuration upsets that plague SRAM FPGAs in orbit. According to Microchip, RTAX-S devices offer live-at-power-up operation, so payload logic is functional immediately after spacecraft power application without a configuration device - valuable during launch and safe-mode events. In use, the FPGA bridges payload sensors to downlink chains through its embedded SRAM with FIFO control logic, buffering data rate mismatches between acquisition and telemetry. The trade-off is that antifuse programming is one-time, so all payload logic must be fully verified before flight-unit programming.
おすすめ
Spacecraft Bus Control and Housekeeping
For spacecraft bus control - power switching sequencing, attitude-control interfacing, and mode management - the RTAX4000S-CQ352V offers a true single-chip solution that replaces multiple rad-hard ASSPs, reducing board area, connector count, and failure modes. Its segmentable clocks and chip-wide highway routing let designers distribute low-skew timing across bus-control state machines spread over the 4M-gate fabric. The live-at-power-up antifuse architecture guarantees that critical power-on sequencing logic is operational the instant primary power arrives, without waiting for configuration loads. Designers typically dedicate a portion of the 40,320 combinational logic blocks to watchdog and voting functions for fault tolerance. The main consideration is that the single-chip form factor concentrates critical functions in one device, requiring SEU-hardened design practices such as triple modular redundancy in the RTL.
おすすめ
Telemetry and Telecommand (TT&C) Interfaces
TT&C subsystems benefit from the RTAX4000S-CQ352V's deterministic, configuration-upset-immune fabric: telecommand decoders and telemetry encoders must be continuously correct, and the one-time-programmable antifuse technology eliminates the configuration-memory single-event upset mechanism entirely. The device's embedded SRAM blocks with built-in FIFO control logic implement frame buffering between the spacecraft low-rate telemetry bus and the RF ground link, while 60,480 logic cells accommodate CCSDS-compliant framing and scrambling functions. Live-at-power-up operation ensures the TT&C chain is reachable during spacecraft initial acquisition, when no processor software has yet booted. Performance-wise, the Axcelerator-derived fabric easily handles the megabit-per-second class data rates typical of TT&C links, leaving timing margin well below the family's maximum clock frequencies.
おすすめ
Deep Space Mission Avionics
Deep space missions face total ionizing dose levels and galactic cosmic-ray fluxes far beyond low Earth orbit, making the RTAX4000S-CQ352V's radiation-tolerant qualification and OTP antifuse fabric a natural fit for avionics FPGA roles. Microchip positions RTAX-S as suitable for 'low Earth orbit, deep space or anything in between.' The ceramic CQ352 column grid array package survives launch vibration, thermal vacuum cycling, and hermetic-seal requirements of deep-space avionics trays. In avionics designs, the 4M-gate capacity hosts sensor interfaces, fault-management logic, and subsystem glue logic in one device, cutting mass - a direct launch-cost benefit. Because SEU rates rise with mission distance, designers pair the hardened fabric with TMR and EDAC structures; the ample logic cells make these overhead architectures practical within a single chip.
おすすめ
Radiation-Tolerant Glue Logic Integration
Spacecraft designs frequently accumulate legacy rad-hard ASSPs, MIL-STD-1553 interfaces, discrete decoding, and bus bridges. The RTAX4000S-CQ352V consolidates these into one 4M-gate device: with 40,320 combinational logic blocks and chip-wide highway routing, engineers integrate address decoders, bus transceiver logic, interrupt controllers, and custom peripherals that would otherwise occupy dozens of rad-hard SSI/MSI packages. Live-at-power-up antifuse behavior means housekeeping decode logic works from the first power cycle, and the single-chip form factor shrinks board area and solder joints - both reliability and mass wins for space hardware. The embedded SRAM with FIFO control absorbs rate mismatches between legacy buses and modern processors. The one-time-programmable constraint means interface protocols must be frozen before flight-lot programming, so thorough simulation of all bus traffic corner cases is essential.
おすすめ
Earth Observation Instrument Control
Earth-observation payloads - imagers, spectrometers, radar front ends - need high-density, low-power FPGA control for detector timing, ADC interfacing, and on-board preprocessing. The RTAX4000S-CQ352V's low-power CMOS antifuse fabric minimizes instrument heat load, which directly benefits thermal design of optical benches, and its 4M gates accommodate detector sequencer trees plus real-time gain/offset correction pipelines. The family's embedded SRAM blocks implement line buffers for pushbroom sensor readout, while segmentable clocks generate the multi-phase timing grids detector arrays require. Single-chip live-at-power-up operation keeps instrument electronics safe through launch and early-orbit checkout without configuration uploads. According to Microchip, low power combined with radiation tolerance is what makes RTAX-S the FPGA of choice for space-flight system designers; instrument control is a canonical example of that value proposition.

設計ノート
RTAX4000S is one-time programmable: every programmed flight unit is consumed. Complete full RTL simulation, static timing analysis, and - where possible - hardware prototyping on the flash-based ProASIC3E adaptor (Microchip/Aldec RTAX prototyping solution) before programming flight lots. Do not iterate designs on flight hardware. Also confirm whether your program requires the S or SL screening flow, since ICCA current limits are tested at 125C final electrical test and lots are differentiated accordingly (source: Microsemi/Mouser RTAX-S documentation).
The CQ352 is a ceramic column grid array using solder columns rather than balls; design the land pattern per the manufacturer datasheet (ds2169) column layout and verify pad geometry against your board fabricator's capability. Plan escape routing for 352 columns early; column-grid arrays tolerate slightly larger pads than BGA but column coplanarity and reflow profiles differ. Check board-level CTE mismatch against spacecraft panel materials, and note that CG1272/LG1272 body sizes differ between RTAX4000S and RTAX4000D devices if your program uses multiple densities.
Antifuse CMOS architecture keeps static power low versus SRAM-based space FPGAs, supporting thermal budgets on optical benches and avionics trays. Obtain exact core/I-O supply voltages and ICCA limits from the RTAX-S/SL datasheet (ds2169) for your power budget - public listings do not state these numerically. Use the segmentable clock conditioning circuitry to gate unused clock domains, further reducing dynamic power in payload sections that operate only during observation windows.
Use the chip-wide highway routing resources for global, high-fan-out signals (resets, mode lines) to minimize skew across the 60,480-cell fabric. Assign telecommand and safety-critical inputs to dedicated I/O with Schmitt or registered inputs where supported, and apply triple modular redundancy in RTL for state machines susceptible to SEU-induced state corruption in high-radiation orbits. Simulate timing at the chosen speed grade; the -1 (RTAX4000S-1CQ352V) grade offers faster timing if closure fails at standard grade.
