RTAX4000SL-CG1272E 概要
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the single-event effects and total ionizing dose encountered in space flight systems. Within the programmable logic hierarchy, the RTAX-SL sits above commercial FPGAs (which lack SEU hardening) and serves as the on-board computation, telemetry, and control backbone of satellites and deep-space probes.
Key features include SEU-hardened flip-flops that eliminate the need for Triple-Module Redundancy (TMR) in most designs, single-event upset immunity up to the specified LET threshold with an SEU rate below 10-10 errors per bit-day, and true single-chip, live-at-power-up operation thanks to flash-based Axcelerator-style architecture with antifuse programming. The 0.15um CMOS process keeps static power low, a decisive advantage for spacecraft power budgets.
Architecturally, the device builds on the AX cell structure with logic modules, embedded SRAM blocks, and high-performance clock resources, allowing glue logic, bus interfaces, and real-time controllers to be consolidated into one ceramic package. The CG1272 column-grid format provides robust mechanical attachment and thermal performance through PCB reflow, suited to launch vibration environments.
Typical applications include satellite payload data processing, spacecraft attitude control units, telemetry/command (TM/TC) interfaces, and instrument control in low-earth-orbit and deep-space missions. The extended -55C to +125C rating covers both cold soak and eclipse heating cycles.
Design consideration: the part is one-time programmable (antifuse), so prototype on the RTAX4000SL-1CG1272PROTO variant or the footprint-compatible Axcelerator adapter-board methodology before committing flight units.

主な用途
RTAX4000SL-CG1272E の用途: 6 件s: Satellite Payload Data Processing, Spacecraft Attitude Control Systems, Telemetry, Tracking and Command (TT&C) Interfaces, Scientific Instrument Control and Data Acquisition, Launch Vehicle and Avionics Electronics, Deep-Space Probe On-Board Computing.
Satellite Payload Data Processing
The RTAX4000SL-CG1272E fits payload processing chains where high gate count (4,000,000 system gates, 40320 logic cells) must coexist with radiation robustness. Its SEU-hardened registers, with an upset rate below 10-10 errors/bit-day per the Microchip RTAX-S/SL datasheet, keep payload formaters, packetizers, and compression engines running without the area and timing overhead of triple-module redundancy. In the payload data path, the FPGA typically sits between instrument front-ends and the downlink formatter, implementing FIFOs, framing, and CRC in the embedded SRAM and logic fabric at a 1.5V core. The CCGA-1272 package provides the I/O count needed for wide parallel instrument interfaces. Because the antifuse fabric is one-time programmable, payload configurations are fixed before launch, eliminating configuration-upset concerns that affect SRAM FPGAs in orbit.

Spacecraft Attitude Control Systems
Attitude control units demand deterministic, upset-immune control loops. The RTAX4000SL-CG1272E hosts star-tracker interfaces, gyro signal processing, and reaction-wheel PWM controllers in one chip, with -55C to +125C operation covering eclipse cold soak and sun heating. Live-at-power-up operation means the control logic is functional the moment the spacecraft wakes - a datasheet-highlighted advantage over SRAM FPGAs that need configuration loading. The SEU-hardened registers (rate below 10-10 errors/bit-day) protect critical loop state machines without TMR replication, preserving timing margin for high-rate control loops. The 1272-pin CCGA supplies abundant I/O for redundant sensor and actuator buses, and the ceramic column-grid construction survives launch vibration. Designers should budget the 1.5V core rail and verify drop performance under worst-case actuator switching on the shared spacecraft bus.
おすすめ
Telemetry, Tracking and Command (TT&C) Interfaces
TT&C boards require radiation-tolerant logic that is always alive. The RTAX4000SL-CG1272E implements CCSDS framing, encryption pre-processing, and command decoders with its 4M-gate fabric and embedded SRAM, while live-at-power-up operation guarantees the receiver chain decodes commands immediately after switch-on, per Microchip's product description. Its SEU-hardened flip-flops (LETTH immunity, sub-10-10 upset rate) protect command legality state machines, and the antifuse fabric cannot suffer configuration upsets in orbit. The -55C to +125C rating matches unheated TT&C compartments on smallsats. With 1272 CCGA columns, the board gains interface headroom for redundant RF modems, dual transponder chains, and ground-test taps. The one-time-programmable nature suits TT&C because the command format is frozen early in the program, eliminating on-orbit reconfiguration risk entirely.

Scientific Instrument Control and Data Acquisition
Space science instruments - imagers, spectrometers, particle detectors - need large glue-less FPGA capacity near the sensor head. The RTAX4000SL-CG1272E provides 40320 logic cells plus 60480 sequential cells, enough to implement detector timing generators, high-speed serial deserializers at the family's supported rates, and on-board co-addition pipelines. The 0.15um CMOS process minimizes static power, which matters for instruments with strict thermal budgets near cryogenic stages. Datasets stream through embedded SRAM FIFOs into mass-memory interfaces across the CCGA-1272's wide I/O ring. Radiation tolerance is intrinsic: SEU-hardened registers hold exposure counters and sequencing state correctly through SAA transits, per the datasheet's sub-10-10 errors/bit-day specification. The extended -55C to +125C industrial-mil temperature window covers instrument bay thermal swings without derating, simplifying the instrument's thermal design.

Launch Vehicle and Avionics Electronics
Launch-stage avionics share space-grade requirements with tighter vibration and thermal profiles. The RTAX4000SL-CG1272E's ceramic column-grid package mechanically complies with PCB CTE mismatch, a key reason CCGA is favored over ball-grid ceramics in launch environments. The device implements flight sequencing, pyrotechnic firing logic, and bus bridges (MIL-STD-1553-style interfaces at the logic level) with deterministic, live-at-power-up behavior essential for ascent timelines. SEU-hardened registers maintain safety-critical interlock state at the datasheet's sub-10-10 upset rate, and the -55C to +125C rating covers unconditioned stage compartments. Because the fabric is antifuse, the flight logic cannot be corrupted in flight, supporting single-fault-tolerant architectures. Designers should validate the 1.5V core supply against stage battery sag during high-current events such as separation.
おすすめ
Deep-Space Probe On-Board Computing
Deep-space missions face the harshest radiation spectra, making the RTAX4000SL-CG1272E's hardening directly relevant. Beyond the SEU-hardened registers, the antifuse configuration stores are immune to configuration upsets that plague SRAM FPGAs during solar particle events. The 4M-gate capacity supports on-board autonomy: fault management, mode scheduling, and science-data triage execute locally instead of relying on round-trip light-time ground commanding. Low static power from the 0.15um process preserves the limited RTG or solar power margin on missions beyond Mars. The device operates across -55C to +125C and its CCGA package survives the multi-year thermal cycling of an outer-planet cruise. According to Microchip, RTAX-S is the FPGA of choice for space designers seeking single-chip, live-at-power-up operation - properties that reduce deep-space failure modes.

設計ノート
RTAX-SL antifuse devices are one-time programmable: a design change consumes a new flight device. Use Microchip's documented prototyping methodology - a footprint-compatible adaptor board plus an EDIF netlist and pinout converter - to iterate on prototyping hardware before committing RTAX4000SL-CG1272E units. Additionally, note the ordering-code suffixes: E, B, GS, and V encode different screening flows; mixing flows across a flight lot can jeopardize program qualification, so lock the exact suffix in your procurement documentation early.
The CCGA-1272 uses solder columns, not balls, precisely to absorb CTE mismatch between the ceramic package and organic PCB. Layout rules from Microchip's RTAX-S/SL datasheet package section specify the column land pattern; do not substitute BGA footprints. Plan redundant power/ground column rows for the 1.5V core and I/O banks, and provide via-in-pad or dog-bone fanout consistent with column pitch. Inspect solder columns with X-ray after reflow - hidden voids in CCGA attach are the leading assembly defect in space boards.
The core supply is 1.5V per the RTAX4000SL-CG1272E datasheet listing; I/O banks run at their own rails per bank configuration. Estimated: static power is low in the 0.15um antifuse fabric, but dynamic power scales with clock rate and toggle activity - verify with Microchip's LibreSL/Designer power estimator for your netlist before sizing the spacecraft 1.5V converter. Provide clean sequencing and bulk decoupling near the CCGA column clusters to handle payload activation transients.
With up to 1272 I/O, simultaneous switching noise on shared return columns is the main SI risk. Group high-toggle-rate outputs to dedicated ground columns, use the datasheet's drive-strength settings to avoid unnecessary overshoot, and terminate single-ended lines per flight-harness practice. For board-to-board links, prefer differential standards supported by the I/O banks and keep stub lengths short under the ceramic package where probing is impossible after assembly.
