RTAX4000DL-1CQ352V 概要
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation and heavy-ion environments of orbital and deep-space missions. Within the programmable-logic hierarchy (FPGA -> programmable logic IC -> digital CMOS IC -> semiconductor), space-grade FPGAs sit at the top of the reliability pyramid, combining reconfigurability with immunity to configuration upsets that would cripple commercial SRAM FPGAs.
Key features of the RTAX4000DL-1CQ352V include its 4-million-system-gate density, the DSP-enhanced DL fabric with embedded multiply-accumulate blocks, embedded SRAM with built-in FIFO control logic, segmentable clock resources, and chip-wide highway routing. True single-chip form factor and live-at-power-up operation eliminate the need for external configuration devices, a decisive advantage where board area and boot reliability are mission-critical.
The RTAX-DSP architecture is based on Microsemi's commercial Axcelerator family, using antifuse one-time-programmable technology that is inherently immune to configuration memory upset. This makes the device a mainstay for payload data processing, onboard image compression, telemetry encoding, and sensor fusion where DSP throughput and radiation tolerance must coexist.
Typical applications include satellite payload signal processing, spacecraft bus control and telemetry, deep-space probe instruments, and launch-vehicle avionics. The DL variant's embedded DSP multipliers offload filtering and FFT workloads from the general fabric, freeing CLB resources for control logic.
Design consideration: because the RTAX-S/DSP family is one-time programmable, designers must validate the full bitstream in the non-hermetic PROTO package variant before committing to flight units in the ceramic CQ352 package.

主な用途
RTAX4000DL-1CQ352V の用途: 6 件s: Satellite Payload Signal Processing, Spacecraft Bus Control and Telemetry, Deep-Space Probe Instruments, Launch Vehicle Avionics, Earth Observation Image Processing, Space-Grade Test and Validation Systems.
Satellite Payload Signal Processing
The RTAX4000DL-1CQ352V fits satellite payload chains because its RTAX-DSP fabric embeds multiply-accumulate blocks that implement FIR filters, FFTs, and image-compression kernels directly in silicon, offloading the 55,440-cell general fabric for control and framing. Its 4,000,000-gate density hosts complete baseband or imaging pipelines in a single chip, and antifuse configuration is immune to configuration-memory upset, removing the need for SEU-scrubbing configuration management. Deployed between an ADC and downlink formatter, the device processes sampled data deterministically with live-at-power-up startup - no configuration load time at orbit insertion. The trade-off versus SRAM space FPGAs is one-time programmability: the validated bitstream is frozen before launch, so verification must complete on PROTO hardware first.
おすすめ
Spacecraft Bus Control and Telemetry
For spacecraft command and data handling, the RTAX4000DL-1CQ352V implements telemetry encoders, decoder chains, and bus interfaces (e.g., MIL-STD-1553 or SpaceWire glue logic) with 36,960 CLBs of configurable registers and state machines. True single-chip live-at-power-up operation means the controller is functional the instant power is applied - critical for autonomy during launch and safe-mode recovery, since there is no external boot PROM to fail. Embedded SRAM with built-in FIFO control buffers telemetry packets without external memory. The V-suffix flight screening and ceramic CQ352 package tolerate launch vibration and thermal cycling. Designers should partition the design so time-critical control paths are registered, taking advantage of the -1 speed grade timing verified on PROTO units first.
おすすめ
Deep-Space Probe Instruments
Deep-space instruments face extreme total ionizing dose and heavy-ion fluence; the RTAX4000DL-1CQ352V's antifuse CMOS fabric is inherently immune to configuration upset, making it a standard choice for instrument sequencers and front-end DSP. The DL variant's embedded MAC resources run matched filtering and on-board compression, cutting downlink bandwidth by processing raw sensor data before transmission. Chip-wide highway routing and segmentable clocks let a single device coordinate multiple instrument channels with deterministic timing, while the 4M-gate capacity absorbs design growth over long development cycles. Because reprogramming after launch is impossible with OTP silicon, mission teams validate on the non-hermetic RTAX4000SL-CQ352PROTO and commit the flight bitstream only after full radiation and functional test campaigns.
おすすめ
Launch Vehicle Avionics
Launch avionics demands deterministic startup and vibration-tolerant packaging; the RTAX4000DL-1CQ352V answers both with live-at-power-up single-chip configuration and a ceramic CQ352 column package qualified for flight environments. Flight computers use the 55,440 logic cells for redundant-voting flight control logic, telemetry framing, and destruct-sequence interlocks, while the DSP fabric accelerates guidance filtering loops. The absence of configuration readout eliminates a common single-point failure mode in high-shock environments. The -1 speed grade timing is identical on PROTO and flight units per the Microchip datasheet, so timing closure achieved in validation transfers directly to flight hardware. Teams should implement triple-modular redundancy in the fabric for single-event-transient mitigation even though configuration itself is upset-immune.
おすすめ
Earth Observation Image Processing
Earth-observation payloads push raw high-resolution sensor data through compression and sharpening pipelines; the RTAX4000DL-1CQ352V implements CCSDS image-compression and 2D convolution engines in its embedded DSP blocks, with the 4-million-gate fabric handling camera timing, DDR-style buffering control, and downlink framing. Embedded SRAM with FIFO control logic stages image lines without external frame buffers, reducing board mass - a direct benefit for smallsat platforms. Radiation tolerance is essential at sun-synchronous and polar orbits where trapped-proton fluence is high, and the antifuse fabric eliminates configuration-upset resets mid-image. A single device replacing multiple ASICs and SRAM-FPGA mitigation logic shortens qualification. The one-time-programmable constraint means the full imaging chain must be validated on PROTO silicon before flight-unit programming.
おすすめ
Space-Grade Test and Validation Systems
Ground support equipment and radiation-test vehicles use the RTAX4000DL-1CQ352V to mirror flight logic exactly: because PROTO units share the flight parts' timing attributes, the same CQ352 footprint supports bench testers, beam-line SEU monitors, and thermal-vacuum test beds. The DL DSP fabric reproduces flight datapath behavior bit-accurately, letting test engineers inject stimulus and compare outputs against flight expectations. With 55,440 logic cells, one tester device can emulate multiple flight units plus instrumentation. Using engineering devices such as the RTAX4000SL-1CQ352E in test equipment preserves scarce flight-screened stock while retaining package-compatible sockets. Design the tester with independent clock domains per device under test so segmented clock resources isolate faults during destructive radiation runs.

設計ノート
The RTAX-DSP family is one-time programmable: once a flight unit is programmed, the bitstream is permanent. Per the Microchip datasheet, PROTO prototype units in non-hermetic ceramic packages carry the same timing attributes as flight RTAX-S/SL and RTAX-DSP units - use them (e.g., RTAX4000SL-CQ352PROTO) for full functional and timing validation before any flight-unit programming. Budget schedule time for this validate-then-program cycle; skipping it risks scrapping irreplaceable flight silicon.
Even though the antifuse configuration fabric is immune to configuration upset, user logic remains susceptible to single-event transients in combinatorial paths. Apply triple-modular redundancy (TMR) on critical registers and control state machines, and use the family's segmentable clock resources to isolate clock domains per function. Verify SEU mitigation strategy with Microchip radiation reports referenced on the RTAX4000DL product page before PDR sign-off.
The CQ352 ceramic column package requires a matching 352-pad land pattern with column-pitch tolerance control; confirm the land pattern from the Microchip package drawing rather than generic CGA footprints. Provide low-impedance core and I/O decoupling close to supply pins, and follow the power-supply sequencing guidance in the RTAX-S/SL and RTAX-DSP datasheet. Because the package is hermetic flight hardware, avoid reflow rework - design first-pass assembly processes around it.
