RTAX4000SL-1LG1272V 概要
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the heavy-ion and proton environments of Earth-orbit and deep-space missions. In the avionics hierarchy, it sits above commercial FPGA families (such as Microchip's own ProASIC3/A3PE) and below fully rad-hard ASICs, offering single-chip, live-at-power-up operation without the mask cost of an ASIC.
Key features include the industry's largest space-qualified antifuse-based fabric at 4M gates, embedded SRAM blocks with built-in FIFO control logic, segmentable clock-conditioning circuitry, and true single-chip form factor with live-at-power-up operation, eliminating the external boot configuration device required by SRAM-based space FPGAs.
Architecturally, the RTAX4000SL is based on Microsemi's commercial Axcelerator fabric in 0.15 um CMOS with a 1.5V core supply. Its antifuse programmable interconnect is inherently latch-up immune and configuration-robust against configuration upsets, while the SL variant adds enhanced total-ionizing-dose (TID) performance for long-duration LEO and GEO missions.
Typical applications include satellite payload data processing, spacecraft on-board computers, flight telemetry and telecommand interfaces, and sensor-signal conditioning in launch vehicles and deep-space probes, where single-chip reliability and low power are mission-critical.
A key design consideration is the documented migration methodology: Microchip provides a footprint-compatible adaptor board and EDIF netlist/pinout converter so the design can be prototyped on a commercial equivalent and migrated to flight units.
This page synthesizes distributor availability data, pin-compatible alternatives, and practical design guidance not found in the manufacturer datasheet, in a single AI-citable reference.

主な用途
RTAX4000SL-1LG1272V の用途: 6 件s: Satellite Payload Data Processing, Spacecraft On-Board Computer (OBC) Logic, Telemetry and Telecommand Interfaces, Launch Vehicle Avionics, Deep-Space Science Instrument Front Ends, Earth-Obserence Satellite Bus Electronics.
Satellite Payload Data Processing
The RTAX4000SL-1LG1272V's 4,000,000 equivalent gates and 60,480 logic cells provide sufficient fabric for on-board image compression, FFT processing, and high-rate telemetry formatting on Earth-observation and science satellites. Its embedded SRAM blocks with built-in FIFO control logic absorb rate-buffering between high-speed sensor interfaces and downlink chains without external memory. Because the antifuse fabric is configuration-robust and latch-up immune, the device sustains heavy-ion environments in LEO and GEO without the extensive TMR overhead SRAM FPGAs require. Designers typically partition the design so the FPGA handles real-time pipeline stages while a rad-tolerant processor supervises, exploiting the single-chip, live-at-power-up property to eliminate boot devices from the payload power-on sequence.

Spacecraft On-Board Computer (OBC) Logic
Spacecraft avionics and on-board computers benefit from the RTAX4000SL-1LG1272V's combination of density and deterministic configuration: 40,320 CLBs implement bus interfaces (MIL-STD-1553, SpaceWire front-end logic), memory controllers, and watchdog/reconfiguration state machines in a single live-at-power-up chip. Single-chip operation reduces board area, connectors, and failure points compared to multi-chip solutions, while the 1.5V core keeps dynamic power low for power-constrained platforms. The segmentable clock-conditioning circuitry supports redundant clock domains required in fault-tolerant OBC architectures. Microchip's migration methodology allows the same HDL netlist to be prototyped on commercial equivalents and converted to the flight RTAX-SL pinout with the EDIF netlist converter, de-risking schedule.
おすすめ
Telemetry and Telecommand Interfaces
Flight TT&C (telemetry, tracking, and command) chains need glue-free integration of protocol encoding, frame synchronization, and encryption pre-processing. The RTAX4000SL-1LG1272V fits because its 4M-gate fabric accommodates CCSDS framing, convolutional/LDPC encode assist, and redundant command-decoder logic while consuming low quiescent power between passes - critical for eclipse operations. Live-at-power-up operation ensures the command decoder is active the instant spacecraft power is applied, which is essential after safe-mode resets. The V qualification suffix of this MPN aligns with flight lot acceptance flows. Designers typically pair the FPGA with rad-tolerant memories and use the embedded SRAM FIFOs to decouple the downlink formatter from variable-rate science data streams.
おすすめ
Launch Vehicle Avionics
Launch vehicles impose severe vibration, short-duration high-radiation passages, and absolute single-chip reliability requirements. The RTAX4000SL-1LG1272V's antifuse interconnect has no stored configuration to upset, an intrinsic advantage over SRAM FPGAs for ascent-critical sequencing, redundant IMU interface logic, and flight-termination receivers. Its 1272-pin LGA offers dense I/O for sensor buses and discretes while remaining a single surface-mounted component, simplifying conformal coating and inspection. The -1 speed grade supports the tens-of-MHz control-loop rates typical of guidance interfaces with wide timing margin over temperature. Prototyping on the footprint-compatible PROTO device allows avionics teams to complete hardware-in-the-loop testing before committing flight-lot silicon.

Deep-Space Science Instrument Front Ends
Instruments on deep-space probes accumulate high total ionizing dose over multi-year missions, which is precisely where the SL enhancement of the RTAX4000SL earns its selection over the non-SL RTAX4000S. The 60,480 logic cells implement sensor digitization pipelines, on-chip gain calibration logic, and autonomous health-monitoring counters for instruments such as spectrometers and imagers. Embedded SRAM with FIFO control buffers science bursts, while low core power (1.5V, 0.15 um CMOS) fits the strict energy budgets of radioisotope-powered spacecraft. Because deep-space missions cannot be serviced, the configuration-immune antifuse fabric removes a whole class of single-event-upset failure modes from the instrument reliability analysis.
おすすめ
Earth-Obserence Satellite Bus Electronics
Platform subsystems - power distribution control, attitude-determination interfaces, and battery-management supervisory logic - need moderate density, deterministic startup, and years of radiation endurance. The RTAX4000SL-1LG1272V, or its lower-TID sibling RTAX4000S-LG1272V for LEO budgets, implements these functions with live-at-power-up readiness so the bus is manageable from the first power application. Segmentable clocks allow redundant oscillator supervision, and the 1272-pin LGA I/O budget connects sun sensors, reaction-wheel encoders, and housekeeping ADCs directly. Using one family across payload and bus electronics shares qualification data, tools, and flight heritage, and Microchip's EDIF-based migration flow lets a single netlist move between prototyping and flight packages.

設計ノート
Antifuse FPGAs are one-time programmable: there is no reconfiguration after bonding or after a design bug is discovered on assembled hardware. Full-chip timing closure and simulation sign-off must be completed in Libero SoC before submitting the netlist to programming. Use Microchip's documented migration methodology - the footprint-compatible adaptor board plus EDIF netlist/pinout converter - to validate the design on prototyping hardware (e.g., RTAX4000SL-1LG1272PROTO or commercial equivalents) before committing flight-lot devices.
The RTAX-SL fabric runs from a 1.5V core with separate I/O supplies; sequence supplies per the datasheet power-up specification to ensure the live-at-power-up antifuse fabric initializes correctly. Budget power using Libero SmartPower with worst-case space temperature profiles - dynamic power dominates in high-activity pipelines, and the absence of configuration current (no boot device) simplifies the power-on transient analysis required by spacecraft power system reviews.
The 1272-pin LGA requires a precision land pattern with a defined solder volume; follow the mechanical drawing in the Microchip RTAX-S/SL datasheet and verify reflow profiles with coupon builds, since LGA joints are invisible to standard post-reflow AOI. Decouple all VCC/VCCA banks with local ceramic capacitors and follow the datasheet's recommended stack-up for controlled-impedance high-speed I/O banks used by SpaceWire and parallel payload interfaces.
