RTAX2000S-CQ352V Présentation
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation of orbital and deep-space environments, sitting within the broader hierarchy of programmable logic devices: FPGA -> radiation-tolerant FPGA -> space-grade semiconductor. Unlike reprogrammable SRAM FPGAs, RTAX-S devices use antifuse programmable interconnect that is inherently immune to configuration upsets and powers up live, eliminating the need for external configuration memory in a single-chip form factor.
Key features include SEU-hardened flip-flops that reduce or eliminate the need for triple-module redundancy (TMR), low static power consumption typical of CMOS antifuse architecture, and true live-at-power-up operation. The CMOS logic family targets 2,000,000 system gates with 21,504 CLBs, providing substantial capacity for payload data processing, telemetry, and bus-interface logic on a single die.
Architecturally, the RTAX2000S belongs to the RTAX-S/SL and RTAX-DSP radiation-tolerant FPGA series documented in the Microchip datasheet. The antifuse fabric is one-time programmable, which prevents ground-radiation-induced configuration loss; SEU immunity to a specified linear energy transfer threshold keeps single-event upset rates below 10^-10 errors per bit-day in typical orbits.
Typical applications include satellite payload controllers, spacecraft on-board data handling, launch-vehicle avionics, and deep-space probe instrument interfaces where MIL-PRF-38535 QML class V screening is often required by the system specification.
Design consideration: the CQ352 ceramic package arrives with leads on a tie bar that must be trimmed, formed, and de-golded before assembly; plan the manufacturing flow and verify the per datasheet supply-current budget against your power budget early.

Applications typiques
RTAX2000S-CQ352V convient pour 6 applications: Satellite Payload Data Processing, Spacecraft On-Board Data Handling, Launch Vehicle Avionics, Deep-Space Instrument Interfaces, LEO Constellation Satellite Electronics, Defense and Military Avionics Upgrade.
Satellite Payload Data Processing
The RTAX2000S-CQ352V is well suited to satellite payload controllers because its 2,000,000 system gates and 21,504 CLBs provide enough capacity for framing, compression, and buffering logic on one chip, while the antifuse fabric is live at power-up with no boot PROM - critical after a reset in orbit. Its SEU-hardened registers keep single-event upset rates below 10^-10 per bit-day, reducing the TMR overhead that SRAM FPGAs demand. Placed between the payload sensor chain and the downlink formatter, it glues interfaces deterministically with no configuration latency; the trade-off is one-time programmability, so the bitstream must be finalized before flight lot release.

Spacecraft On-Board Data Handling
For spacecraft on-board computer I/O and bus-interface logic, the RTAX2000S-CQ352V offers 32,256 logic cells for MIL-STD-1553, SpaceWire, and CAN controller wrappers alongside telemetry aggregation. The hermetic CQ352 ceramic package rated -55C to +125C withstands launch vibration and thermal cycling that plastic-packaged FPGAs cannot. Low CMOS static power helps meet tight satellite power budgets, and single-chip operation removes the configuration-device failure mode from the reliability analysis. Designers typically place it downstream of the rad-hardened processor, offloading real-time protocol tasks; verify per-bank supply current against the datasheet power tables during the power budget review.
Recommandé
Launch Vehicle Avionics
Launch-vehicle flight computers demand electronics screened for extreme environments, where the CQ352 hermetic ceramic quad flat package is specified because qualified plastic QFPs are not acceptable. The RTAX2000S-CQ352V supplies 2,000,000 gates of glueless interface logic between the guidance processor, IMU, and actuator drivers, with live-at-power-up operation guaranteeing logic is active the instant power is applied. SEU-hardened flip-flops withstand the high-flux portion of ascent trajectories. Note the mechanical consideration: CQFP leads arrive on a tie bar and must be trimmed, formed, and de-golded before reflow, so plan the assembly flow with your contract manufacturer early.
Recommandé
Deep-Space Instrument Interfaces
Deep-space probes expose electronics to galactic cosmic rays for a decade or more, making the RTAX2000S-CQ352V antifuse architecture attractive: configuration cannot be upset by radiation, and SEU rates below 10^-10 errors per bit-day meet typical outer-planet reliability targets without exhaustive TMR. Its 21,504 CLBs implement instrument sequencers, science-data packers, and sensor timing generators. The -55C to +125C operating range accommodates the cold survival heater-off cases common on planetary missions. Place it next to the instrument ADC chain to timestamp and compress data; budget for one-time programming early since flight software iterations cannot re-target the fabric in-orbit.

LEO Constellation Satellite Electronics
Low-Earth-orbit mega-constellations balance cost against radiation exposure in the South Atlantic Anomaly, and the RTAX2000S-CQ352V offers a middle path: true radiation-tolerant antifuse logic without the price of full rad-hard ASICs, per Microchip's positioning of RTAX-S as an alternative to radiation-hardened ASICs. The 2,000,000-gate capacity implements a complete attitude-control interface, beacon encoder, and housekeeping telemetry in one live-at-power-up chip. Compared with SRAM FPGA alternatives, the board drops the configuration flash and its scrubber, saving mass and a failure mode. For high-volume constellation procurement, quote-based ordering through authorized distributors with lot traceability is standard.
Recommandé
Defense and Military Avionics Upgrade
Legacy military platforms undergoing avionics mid-life upgrades use the RTAX2000S-CQ352V to replace obsolete bipolar and first-generation FPGA logic while retaining the existing conduction-cooled card format, because the 352-pin ceramic CQFP footprint matches legacy ceramic-package land patterns common in MIL-PRF-38535 programs. The -55C to +125C rating and hermetic package meet platform environmental specifications, and live-at-power-up antifuse logic simplifies built-in-test sequencing at aircraft power-on. One-time programmability is acceptable here since deployed configurations are frozen. The DLA cross-reference framework applies to qualified drawing parts in this family for defense procurement.

Principaux différenciateurs
- Antifuse configuration immunity (vs SRAM-based space FPGAs)
- Pin-compatible upgrade path within CQ352 (vs RTAX4000S-1CQ352V)
- SEU-hardened registers reduce TMR overhead (vs Non-hardened FPGA fabrics)
Notes de conception
RTAX2000S/SL and RTAX2000D/DL are NOT pin compatible in the CQ352 package, per the Microchip RTAX-S/SL datasheet - a swap that looks die-compatible on paper will not land on the same footprint. However, RTAX4000S/SL devices ARE pin compatible with RTAX2000S/SL in CQ352, so reserve the RTAX4000D family for new layouts only. Confirm the exact ordering-code suffix (speed grade and screening) before release, because these determine timing closure and flight-lot documentation.
The CQFP package arrives with straight leads locked into a ceramic tie bar; they must be trimmed, formed, and de-golded before solder assembly. Coordinate with your contract manufacturer on lead-forming tooling and inspection criteria, and verify land-pattern geometry against the CQ352 package drawing in the Microchip datasheet rather than reusing a generic 352-pin QFP footprint - hermetic ceramic packages have different body and lead dimensions than plastic QFPs.
RTAX-S antifuse FPGAs power up live with no configuration current surge or boot PROM, simplifying inrush analysis for spacecraft power systems. Nevertheless, derive static and dynamic core current from the datasheet power tables using your actual toggle rates and enter conservative numbers in the mission power budget. Add per-rail bulk and ceramic decoupling at the CQ352 power/ground pairs as specified in the manufacturer power-application guidance.
