RTAX4000SL-1LG1272E Übersicht
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environment of space, where total ionizing dose (TID) and single-event effects (SEE) would disable standard commercial devices. Within the power hierarchy of programmable logic, the RTAX-SL family sits at the top: it is a one-time-programmable, antifuse-based FPGA designed specifically for space-flight systems, complementing lower-density space-grade CPLDs and competing alongside larger rad-hard SoC devices.
Key features include true single-chip operation (no external configuration PROM required), live-at-power-up (LAPU) functionality that makes the device active immediately upon power application, low static power consumption from the antifuse interconnect architecture, and a maximum combinatorial delay of 0.99 ns per CLB. These attributes directly address the reliability and startup requirements of satellites and deep-space probes.
Architecturally, the RTAX-SL family combines Sea-of-Modules logic (Combi and Sequential cells), embedded SRAM blocks, and high-performance clock circuitry on the 0.15 um metal-to-metal antifuse process. One-time programmability means configuration data cannot be disturbed by configuration upsets, a significant SEE advantage over SRAM-based FPGAs, though it precludes in-orbit reconfiguration.
Typical applications include satellite payload data processing, telemetry and telecommand subsystems, spacecraft bus control, and radiation-tolerant glue logic consolidation, where the 4M-gate density absorbs functions that would otherwise require multiple rad-hard ASICs or SSI/MSI devices.
Design consideration: as a one-time-programmable device, the RTAX4000SL requires thorough functional verification in the prototyping flow (typically using Microchip's footprint-compatible RTAX-S prototyping methodology) before committing flight hardware.

Typische Anwendungen
RTAX4000SL-1LG1272E ist geeignet für 6 Anwendungs: Satellite Payload Data Processing, Spacecraft Bus Control and Command Subsystems, Instrumentation and Sensor Front-End Digital Processing, Launch Vehicle Avionics, Radiation-Tolerant Glue Logic Consolidation, Deep-Space Probe Electronics.
Satellite Payload Data Processing
The RTAX4000SL-1LG1272E fits payload data-processing chains that must withstand total ionizing dose and single-event effects without configuration loss. With 4,000,000 equivalent gates, 60,480 logic cells, and a 0.99 ns maximum CLB combinatorial delay on the 0.15 um antifuse process, it absorbs high-throughput functions such as image preprocessing, compression front-ends, and channel coding at densities beyond the RTAX2000SL. Its one-time-programmable fabric cannot suffer configuration-memory upsets, a key SEE advantage over SRAM FPGAs, and the 1.5 V core keeps static power low for power-limited spacecraft. The trade-off is lack of in-orbit reconfiguration, so all functionality must be frozen pre-launch.
Empfohlen
Spacecraft Bus Control and Command Subsystems
For telemetry, tracking, and command (TT&C) electronics, the RTAX4000SL-1LG1272E provides live-at-power-up (LAPU) operation, meaning the FPGA is functional the instant bus power is applied - essential during launch sequencing and power-cycled ground testing. The true single-chip form factor eliminates the external configuration PROM that adds parts, mass, and failure modes. The 1272-pin LGA supplies abundant I/O for interfacing with rad-tolerant microcontrollers, memories, and redundant bus transceivers, while the antifuse architecture ensures deterministic startup behavior. Designers should implement triple-module redundancy in RTL for sequential logic because fabric upsets, though rare, remain possible.
Empfohlen
Instrumentation and Sensor Front-End Digital Processing
Spaceborne scientific instruments - spectrometers, star trackers, and imaging sensors - generate high-rate digital streams that the RTAX4000SL-1LG1272E can buffer, format, and pre-reduce before downlink. Its 4M-gate fabric and 0.99 ns CLB delay support parallel datapaths and FIFO/serdes-style interfaces, while the 1.5 V core supply minimizes heat near thermally sensitive detectors. The radiation-tolerant antifuse fabric maintains timing integrity across the mission dose profile, avoiding the configuration-refresh complexity SRAM FPGAs impose in the same environment. Because the device is programmed once, instrument modes must be fixed at design time; the large capacity allows multiple operating modes to be compiled into a single fusemap.
Empfohlen
Launch Vehicle Avionics
Launch-vehicle flight computers and stage-control electronics face extreme vibration and short but intense radiation exposure. The RTAX4000SL-1LG1272E's land-grid-array contacts and single-chip construction support mechanically robust boards, while live-at-power-up operation guarantees the logic is active through battery-cyc avionics power sequences. The 0.15 um antifuse fabric delivers deterministic timing (0.99 ns maximum CLB combinatorial delay) needed for hard-real-time sequencing, and 60,480 logic cells consolidate sequencers, safety interlocks, and bus interfaces that would otherwise span multiple rad-hard ASSPs. Prototyping on RTAX4000SL-1LG1272PROTO hardware allows full functional verification before flight-device programming.
Empfohlen
Radiation-Tolerant Glue Logic Consolidation
Space programs traditionally fill boards with rad-hard SSI/MSI devices; the RTAX4000SL-1LG1272E replaces dozens of these with one 4M-gate device, cutting board area, mass, assembly cost, and interconnect failure points. The 1272-pin LGA provides the I/O breadth to interface legacy MIL-STD buses, memories, and custom ASICs, while 0.99 ns worst-case CLB delay easily covers address decoding, bus bridging, and control-sequencing functions. Live-at-power-up and single-chip configuration remove bring-up complexity in mixed-vendor systems. The one-time-programmable constraint is acceptable here because glue logic is functionally stable, making this consolidation one of the lowest-risk uses of the RTAX-SL family.
Empfohlen
Deep-Space Probe Electronics
Deep-space missions accumulate total ionizing dose over a decade or more and cannot be serviced, demanding components with proven radiation tolerance. The RTAX4000SL-1LG1272E's antifuse configuration is immune to configuration-memory corruption, its 1.5 V CMOS core minimizes leakage-driven power drain as devices age, and the single-chip form factor removes external configuration storage that would itself need radiation qualification. The 60,480 logic cells support autonomous fault-management logic, science-data formatting, and subsystem controllers within one device. Designers must complete all verification before launch because no reprogramming is possible; the EDIF netlist migration flow to prototyping silicon supports this discipline.

Wichtigste Unterscheidungsmerkmale
- One-time-programmable antifuse fabric eliminates configuration upset risk (vs. RTAX4000S-LG1272V)
- Largest RTAX-SL density in the 1272-pin package (vs. RTAX250SL-1LG624E)
- Live-at-power-up, single-chip configuration (vs. SRAM-based space FPGAs (e.g., Xilinx Virtex-QV class))
Designhinweise
The RTAX4000SL is one-time programmable (antifuse). Any functional change after programming requires a new device - there is no in-system reconfiguration or firmware update path. Complete all simulation, timing closure, and hardware verification in Microchip's Libero flow, and prototype on the footprint-compatible RTAX4000SL-1LG1272PROTO before releasing the fusemap to flight silicon. Budget extra schedule time for this verification loop; it is the single largest schedule risk in RTAX-SL programs.
With 1272 LGA contacts, power integrity dominates signal integrity. Follow the RTAX-S/SL datasheet's power-supply decoupling recommendations for the 1.5 V core and I/O banks, using multiple bulk plus high-frequency ceramic capacitors distributed across the land pattern. Series-terminate high-speed I/O to control reflections on back-terminated spacecraft harnesses, and respect the 0.99 ns worst-case CLB combinatorial delay when closing timing on long combinational paths - register heavily between functional blocks.
Even though the antifuse configuration is SEE-immune, the routing and sequential fabric are not. Apply triple-module redundancy (TMR) to state machines and control registers, use EDAC or CRC on external memories, and follow Microchip's rad-tolerant design application notes for RTAX-S/SL. Estimated: a single-event functional interrupt rate budget should be derived from your mission's orbital environment, not assumed from the datasheet alone - obtain mission-specific SEE test reports from Microchip for the RTAX4000SL.
The 1.5 V core supply on a 0.15 um process yields low static power, but dynamic power scales with clock frequency and switching activity on 60,480 logic cells. Estimated: for payload data processing above 50 MHz, perform a Libero power analysis early; supply plane resistance across a 1272-contact LGA requires a solid core power plane. Verify live-at-power-up inrush behavior against your spacecraft's current-limit protections, as antifuse FPGAs draw their full static current immediately at power application.
