RTAX4000D-1CQ352E 概述
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environments of Earth-orbiting and deep-space missions, where standard commercial FPGAs would suffer single-event upsets (SEUs) and total ionizing dose (TID) degradation. Within the space-product hierarchy, the RTAX-DSP family sits among antifuse-based, live-at-power-up radiation-tolerant devices under the broader Microchip (formerly Actel/Microsemi) space FPGA portfolio.
Key features include a 4M-gate density suitable for complex on-board data processing, embedded SRAM blocks with built-in FIFO control logic, segmentable chip-wide clock routing highways, and single-chip operation with no external configuration device required. The antifuse architecture is inherently immune to configuration upsets, a decisive advantage over SRAM-based FPGAs in orbit.
Technically, the device is derived from the commercial Axcelerator architecture and adds radiation tolerance through process and design hardening. Core operation at 1.5 V keeps dynamic power low, an important consideration for solar- and battery-powered spacecraft payloads. DSP-oriented resources support on-orbit image processing, software-defined radio, and telemetry encoding.
Typical applications include satellite payload processing, launch-vehicle avionics, and deep-space probe instrument control, where low power, live-at-power-up behavior, and SEU robustness are mission-critical.
Design consideration: verify radiation report data (TID and SEE performance) against the specific mission orbit and validate the timing model for the -1 speed grade before design freeze.

典型应用
RTAX4000D-1CQ352E 适用于 6 应用s: Satellite Payload Data Processing, Launch Vehicle Avionics, Deep-Space Instrument Control, Software-Defined Radio Payloads, Spacecraft On-Board Computing, Prototype and Development Builds.
Satellite Payload Data Processing
The RTAX4000D-1CQ352E fits satellite payload processing because its 4,000,000 equivalent gates and 36,960 CLBs provide enough fabric for on-board image compression, packetization, and encryption, while the RTAX-DSP multiply resources accelerate the filtering and transform stages typical of Earth-observation payloads. Its antifuse configuration is live at power-up and immune to configuration-memory upsets, removing the need for external configuration storage or scrubbing logic that SRAM-based flight FPGAs require. The 1.5 V core keeps dynamic power low on solar- and battery-limited buses, and the ceramic CQFP package withstands the thermal cycling of low-Earth-orbit missions. Place the FPGA at the center of the payload data path with the embedded SRAM FIFOs buffering sensor-to-downlink data flow.
推荐
Launch Vehicle Avionics
Launch-vehicle flight computers and telemetry encoders benefit from the RTAX4000D-1CQ352E because launch environments impose extreme vibration and radiation exposure during passage through the Van Allen belts, and the ceramic CQFP-352 package plus antifuse fabric are proven in such conditions. The -1 speed grade supports real-time control loop closure, while 36,960 CLBs implement redundant-channel voting, telemetry formatting, and separation-event sequencing in a single chip, reducing board count and single-point failures. Live-at-power-up operation ensures the device is operational the instant battery power is applied, which matters for vehicles that cannot tolerate configuration boot delays. Verify SEE and TID figures against the specific flight profile using Microchip radiation reports before design freeze.
推荐
Deep-Space Instrument Control
Deep-space probes operate for decades in high-radiation environments where total ionizing dose and single-event effects dominate reliability, making the RTAX4000D-1CQ352E's radiation-tolerant 0.15 um CMOS process appropriate for instrument sequencing and science-data acquisition. Its 4M-gate capacity hosts instrument state machines, FIFO-based data acquisition using the embedded SRAM blocks, and DSP pre-processing of sensor streams before the low-rate downlink. Power is extremely scarce beyond Mars, and the 1.5 V core supply directly reduces switching losses in the limited solar/battery budget. The single-chip, no-boot antifuse design eliminates configuration-storage failure modes over long mission durations, and the -1 timing model supports deterministic, conservative instrument timing closure.
推荐
Software-Defined Radio Payloads
Space SDR transponders need substantial multiply-accumulate throughput combined with radiation tolerance, and the RTAX4000D variant delivers exactly this combination through its DSP-oriented resources within the 4M-gate fabric. Typical implementations use the 36,960 CLBs for channel filtering, the embedded SRAM FIFOs for symbol buffering, and segmented chip-wide clock routing to isolate the high-speed digital modulator from sensitive analog interface timing. The antifuse configuration guarantees the radio is on-air immediately at power-up with no configuration fetch, important for coherent beacon operation. Compared with reprogrammable SRAM flight FPGAs, the fixed fabric trades post-launch flexibility for upset immunity and lower SEU-mitigation overhead, which often nets higher available throughput per watt on the 1.5 V core.
推荐
Spacecraft On-Board Computing
As a general on-board computing element, the RTAX4000D-1CQ352E implements memory controllers, bus interfaces, and housekeeping telemetry in one chip: embedded SRAM with built-in FIFO control handles buffering, chip-wide highway routing distributes clocks across the die, and 4M gates provide headroom for interface consolidation as subsystems merge. Segmentable clocks let designers partition time-critical control sections from slower telemetry logic, easing timing closure at the -1 speed grade. Live-at-power-up antifuse behavior suits watchdog and reset supervision roles where the device must gate other rails from the first millisecond. The 352-pin CQFP offers a manageable pin count for medium-complexity boards and a ceramic body compatible with conventional space-qualified assembly flows.
推荐
Prototype and Development Builds
Although RTAX4000D-1CQ352E is a flight-grade part, Microchip's prototype flow for the RTAX-S/SL and RTAX-DSP families offers units in non-hermetic ceramic packages with the same timing attributes as flight units, letting teams close timing and validate RTL against flight-representative models before committing to expensive ceramic CQFP hardware. Designs target the same 36,960-CLB architecture and -1 speed grade in Microchip Libero SoC, so the netlist migrates directly to RTAX4000D-1CQ352E for flight. This two-step approach de-risks program schedules: logic and I/O assignments verified on prototype units carry over pin-for-pin to the CQ352 flight package, while radiation screening and lot qualification are applied only to the final flight build.

设计说明
Core rails at 1.5 V dominate dynamic power in the RTAX4000D; estimate total power in Microchip Libero SmartPower with your actual toggle rates before sizing the spacecraft DC-DC converter. Decouple every VCC and VCCA pin with 0.1 uF ceramics placed within 2 mm of the pin, plus bulk 10 uF per rail. Estimated: a 4M-gate fabric at moderate utilization can draw on the order of watts, so plan thermal paths through the ceramic CQFP body and board copper accordingly.
The 352-pin CQFP requires careful land-pattern design: follow the mechanical drawing in the RTAX-S/SL and RTAX-DSP datasheet (rtaxs_ds2169) exactly, and verify the corner lead orientation of the CQ352 package against your footprint before fabrication. Use equal-length tuned routing for clock and high-speed I/O, and do not route signals under the package body without ground stitching. Note that the 1272-pin CG/LG package bodies of RTAX4000D/DL are larger (42.5 mm) than RTAX4000S/SL equivalents - relevant if your design may migrate packages later.
Antifuse FPGAs are one-time programmable: a design error in the programming file destroys the unit, so exhaustively verify the netlist in simulation and on prototype units before programming flight hardware. Programmed RTAX4000D parts cannot be reworked. Additionally, confirm that temperature grade suffix (E vs standard) matches your mission thermal analysis, and request Microchip radiation test reports (TID/SEE) for the specific lot when qualifying for flight.
