RTAX4000SL-1CG1272EV 概要
A radiation-tolerant FPGA is a field-programmable gate array designed to survive the ionizing radiation environment of space, where single-event upsets (SEU) and total ionizing dose (TID) would corrupt conventional commercial devices. Within the power-management hierarchy of spacecraft avionics, the RTAX-SL family sits at the payload-processing and control level, providing true single-chip, live-at-power-up logic based on antifuse technology.
Key features include SEU-hardened flip-flops that eliminate the need for triple-module redundancy (TMR) in many designs, SEU immunity verified to a specified LET threshold with an SEU rate below 10-10 errors per bit-day, embedded SRAM blocks with built-in FIFO control logic, and segmentable clocking resources. The 0.15um CMOS process yields low static power consumption, a decisive advantage in power-limited satellites.
Architecturally, the RTAX-SL family derives from the commercial Axcelerator family, giving designers a proven fabric with cluster-based logic modules, chip-wide routing, and high-performance I/O. A documented prototyping flow lets designs be validated on commercial Axcelerator devices using footprint-compatible adaptor boards and EDIF netlist conversion before flight-device commit.
Typical applications include satellite payload data processing, spacecraft bus control, telemetry and telecommand interfaces, and radiation-exposed instrumentation where live-at-power-up operation removes the need for external configuration memory, a common failure point in space systems.
Design consideration: because the device is one-time programmable antifuse, verify the netlist fully on the prototyping flow before programming flight units, and budget board clearances for the 1272-column ceramic package's reflow and inspection requirements.

主な用途
RTAX4000SL-1CG1272EV の用途: 6 件s: Satellite Payload Data Processing, Spacecraft Bus Control and Avionics, Telemetry, Tracking and Command (TT&C) Interfaces, Instrumentation and Sensor Data Acquisition, Launch Vehicle and Reentry Systems, Ground Test and Prototyping for Space Designs.
Satellite Payload Data Processing
The RTAX4000SL-1CG1272EV provides 4,000,000 equivalent system gates and 40,320 logic cells, enough fabric to implement payload data formatting, compression pre-processing, and high-speed serial or parallel interfaces in a single chip. Its SEU-hardened registers hold an SEU rate below 10-10 errors per bit-day, so payload datapaths survive particle strikes without triple-module redundancy overhead, freeing roughly two-thirds of flip-flop resources versus TMR on commercial FPGAs. Embedded SRAM blocks with built-in FIFO control logic buffer data streams between sensors and downlink chains, and the 1.5V, 0.15um process keeps static power low - often the binding constraint on power-limited small satellites. Live-at-power-up antifuse configuration removes the configuration-memory single point of failure during launch and orbit entry.
おすすめ
Spacecraft Bus Control and Avionics
For spacecraft bus controllers, the RTAX4000SL-1CG1272EV implements command decoding, telemetry formatting, mode control, and fault-management state machines where determinism and radiation robustness dominate. Live-at-power-up operation means control logic is active the instant power is applied - essential for launch-vehicle sequencing and safe-mode entry without a configuration-load window. The -55C to +125C operating range and ceramic CCGA-1272 package withstand the thermal cycling and vibration of launch environments, and segmentable clocking resources let designers isolate timing domains for processor interfaces, redundant computers, and watchdog functions. Because the fabric derives from the commercial Axcelerator family, bus-control RTL validated in prototyping ports with minimal change via the documented EDIF netlist conversion flow.
おすすめ
Telemetry, Tracking and Command (TT&C) Interfaces
TT&C chains demand logic that never loses configuration and tolerates cumulative dose over multi-year missions. The RTAX4000SL-1CG1272EV's antifuse fabric is live at power-up and immune to configuration upsets, addressing the classic weakness of SRAM FPGAs in command receivers where an upset during reception could cause lost telecommands. With 4M gates, engineers can integrate multiple redundant command decoders, majority voters, and format converters in one CCGA-1272 device, reducing board count and connector count in the command chain. The device's SEU rate below 10-10 errors/bit-day bounds ground-station-visible bit-error contributions, and the 1.5V core supply keeps quiescent power compatible with eclipse-budgeted spacecraft power systems.
おすすめ
Instrumentation and Sensor Data Acquisition
Space science instruments - imagers, spectrometers, particle detectors - need timing generators, ADC/DAC interfaces, and real-time pre-processing co-located on a radiation-tolerant die. The RTAX4000SL-1CG1272EV supplies 40,320 logic cells plus embedded SRAM with FIFO control for ping-pong buffering of detector frames, and its 0.15um process delivers the deterministic timing needed for CCD/CMOS clocking sequences. SEU-hardened registers keep acquisition state machines stable through South Atlantic Anomaly passes without TMR. The wide -55C to +125C rating accommodates instrument housings without active thermal control, and the CCGA-1272 ceramic package offers the hermeticity and column-grid mechanical compliance that space-qualified assembly processes require for large die.
おすすめ
Launch Vehicle and Reentry Systems
Flight-control and sequencing electronics in launch vehicles and reentry vehicles operate under extreme vibration, wide temperature excursions, and radiation exposure - a combination few programmable devices survive. The RTAX4000SL-1CG1272EV combines the -55C to +125C ceramic CCGA-1272 package, column-grid solder compliance that relieves board flex stress, and SEU-immune fabric (rate below 10-10 errors/bit-day) for guidance, navigation, and flight-termination logic. Live-at-power-up antifuse configuration guarantees the sequencer is operational at battery activation with no configuration load latency, and one-time programming prevents in-flight configuration corruption. Designers prototype on the commercial Axcelerator equivalent before committing scarce flight units.
おすすめ
Ground Test and Prototyping for Space Designs
Microchip's documented methodology lets teams validate RTAX-SL designs at commercial cost before programming flight die: target the design to the equivalent Axcelerator commercial FPGA, map the commercial package to the RTAX-S/SL footprint using Extender adaptor boards, and migrate the netlist with the EDIF netlist and pinout converter. XAIPART stocks several Axcelerator (A3PE3000) and RTAX PROTO variants for this purpose. This flow exercises the identical RTL and pin assignments destined for the RTAX4000SL-1CG1272EV, catching functional and timing defects while flight units remain unprogrammed - critical because antifuse devices are one-time programmable and CCGA-1272 flight parts carry long lead times measured in months.

- True single-chip, live-at-power-up configuration （vs SRAM-based space FPGAs (e.g., Xilinx Virtex-QV class))

- Honest trade-off: single-source supply （vs RTAX4000S-CG1272V)
設計ノート
RTAX-SL devices are one-time-programmable antifuse FPGAs: a programming error or netlist defect permanently consumes a flight unit that may have a multi-month lead time and a five-figure price. Always complete the full prototyping flow - target the equivalent commercial Axcelerator device, validate on Extender adaptor boards, and convert the netlist with the EDIF pinout converter - before committing any RTAX4000SL-1CG1272EV to programming. Maintain configuration-file checksums and programmer logs as part of flight hardware traceability.
The CCGA-1272 ceramic column grid array uses solder columns rather than spheres, which provides compliance for CTE mismatch between the ceramic package and typical polyimide flight boards, but assembly requires column inspection and X-ray verification. Provide the land pattern exactly per the Microchip package drawing in the RTAX-S/SL datasheet, allow under-clearance for column rework, and follow program-approved space-grade reflow profiles. Do not substitute BGA rework practices blindly - column attachment and inspection criteria differ.
The 1.5V core supply of the 4M-gate RTAX4000SL fabric dominates static power, which is one reason to select the SL (low-power process) variant over the RTAX4000S when the mission is power-limited. Estimate total power using Microchip's Libero power calculator with your actual utilization and toggle rates rather than worst-case assumptions; oversizing the 1.5V rail converter wastes mass and board area. Decouple core and I/O rails per the datasheet recommendation with low-ESR ceramic capacitors placed at the package corners.
