Typical Applications

RTAX1000SL-1CGS624V is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Telemetry, Tracking & Command (TT&C), Launch Vehicle Avionics, Deep-Space Probe Instrument Control, Space-Grade Glue Logic Integration, Space Imaging & Sensor Front-End Processing.

🖥️

Satellite Payload Data Processing

In LEO and GEO satellite payloads, the RTAX1000SL-1CGS624V formats, buffers, and pre-processes high-rate sensor and communication data. Its 1,000,000 system gates and 12,096 logic cells accommodate data framing, FIFO-based rate adaptation using embedded SRAM, and channel coding front-ends. The SEU-hardened registers, with SEU rates below 10-10 errors/bit-day per the Microchip datasheet, keep payload logic functional without heavy triple module redundancy, saving gates and timing margin. The antifuse fabric eliminates configuration upsets entirely - a decisive advantage over SRAM FPGAs in orbit. The SL low-power process reduces static current for solar/battery power budgets, and the 624-pin CGA package supplies enough I/O for wide parallel data buses at -55C to +125C.

🌐

Spacecraft Telemetry, Tracking & Command (TT&C)

TT&C subsystems demand deterministic, always-on logic: the RTAX1000SL-1CGS624V is live at power-up thanks to its antifuse configuration, requiring no external boot PROM and no configuration load time - critical during launch and safe-mode events. The device implements command decoders, telemetry formatters, and watchdog logic across its 12,096 logic cells with chip-wide highway routing for global control signals. Operation from -55C to +125C covers eclipse-driven thermal swings, and the SEU-hardened flip-flops keep command paths immune to single-event upsets to the specified LET threshold. The CGA-624 ceramic package provides the mechanical robustness and solder-column reliability required for vibration-intensive launch environments.

✈️

Launch Vehicle Avionics

Launch-vehicle flight computers and stage-control electronics operate for minutes in an extreme vibration and radiation environment, where live-at-power-up and configuration immunity are non-negotiable. The RTAX1000SL-1CGS624V's antifuse interconnect cannot suffer configuration single-event upsets, and its SEU-hardened registers deliver SEU rates below 10-10 errors/bit-day, per the Microchip datasheet - well suited to short, high-reliability flights. Segmentable clocks support multiple redundant timing domains, and dedicated carry logic accelerates guidance arithmetic datapaths within the 1M-gate fabric. The ceramic column grid array withstands launch shock better than plastic BGA packaging, and the -1 speed grade covers typical avionics timing closure with margin.

🧩

Deep-Space Probe Instrument Control

Deep-space missions face total ionizing dose and upset environments far harsher than LEO, making the RTAX1000SL-1CGS624V's radiation-tolerant antifuse architecture a strong fit for instrument sequencing, detector timing, and science-data acquisition. The SL low-power process minimizes static draw when solar flux is weak at large heliocentric distances, directly extending mission power margins. Embedded SRAM with built-in FIFO control buffers instrument data bursts without external memory parts, reducing board-level component count and failure points. SEU-hardened registers eliminate mandatory triple module redundancy for many control paths, freeing logic for science functions within the 12,096 logic cells and 1M system gates. The EV screening variant is recommended for the most severe missions.

🔧

Space-Grade Glue Logic Integration

Radiation-tolerant designs historically consumed many rad-hard ASICs and SSI/MSI parts for bus interfacing, address decoding, and protocol adaptation. A single RTAX1000SL-1CGS624V integrates this scattered logic into one 624-pin CGA device, cutting component count, board area, and solder joints - each a reliability gain in space hardware. With 1,000,000 system gates, the device absorbs legacy bus bridges, memory controllers with FIFO control from embedded SRAM, and custom peripheral interfaces. Live-at-power-up behavior ensures the integrated logic is functional immediately at spacecraft power application, and the antifuse fabric's configuration immunity removes scrubbing infrastructure that glue-logic SRAM FPGAs would require. This consolidation approach shortens radiation design reviews compared with discrete rad-hard logic builds.

🎥

Space Imaging & Sensor Front-End Processing

CCD and CMOS imaging payloads on Earth-observation satellites use the RTAX1000SL-1CGS624V to generate precise detector timing, perform correlated double sampling control, and pack image data for downlink. The -1 speed grade plus dedicated carry logic handles pixel-rate arithmetic, while embedded SRAM FIFOs absorb bursts between the sensor interface and the mass-memory. SEU-hardened registers protect timing generators whose corruption would create defective imagery, achieving sub-10-10 errors/bit-day upset rates without full TMR per the Microchip datasheet. The 624 I/O positions accommodate wide parallel sensor heads, and the CGA ceramic package maintains signal integrity and mechanical stability across the -55C to +125C orbital thermal range, making it a proven choice on imaging missions.

What is the RTAX1000SL-1CGS624V?
The RTAX1000SL-1CGS624V is a 1,000,000-system-gate radiation-tolerant antifuse FPGA from Actel (now Microchip Technology/Microsemi) with 12,096 logic cells in a 624-pin ceramic CGA package rated from -55C to +125C. According to the Microchip RTAX-S/SL datasheet, it uses SEU-hardened registers and live-at-power-up antifuse technology, making it a leading choice for space-flight systems such as satellites and deep-space probes.
What is the price of RTAX1000SL-1CGS624V?
The RTAX1000SL-1CGS624V is a space-grade device sold primarily via quotation rather than standard catalog pricing; per-unit pricing varies strongly with screening level, date code, and available stock, as of 2026-09-02. Space-grade FPGAs in this class typically command premium pricing from specialist distributors such as Jotrin and VEKEMO. Contact XAIPART or listed distributors with your required quantity and screening requirements for a current, binding quote.
Where can I buy RTAX1000SL-1CGS624V online?
The RTAX1000SL-1CGS624V can be sourced from specialist distributors including Jotrin Electronics, VEKEMO FPGA, FPGAkey, and Ampheo, which list stock and quote services for this Actel/Microsemi part as of 2026-09-02. Because this is a low-volume, high-reliability aerospace component, most distributors operate a quote-and-verify flow rather than instant checkout. Always verify date codes and request traceability documentation for flight programs.
What is the lead time for RTAX1000SL-1CGS624V?
Lead time for the RTAX1000SL-1CGS624V depends on distributor stock versus factory orders; distributor listings (Jotrin, VEKEMO) show stock-in-hand availability for some quantities as of 2026-09-02. New factory production of rad-tolerant RTAX-S devices generally involves long lead times. For flight programs, order well in advance and confirm screening (V-grade) flow and traceability paperwork with the distributor before committing to a schedule.
What is the difference between RTAX1000SL and RTAX1000S?
The RTAX1000SL is the low-power 'SL' variant of the RTAX1000S, using a process option that reduces static power consumption while keeping the same 1,000,000 system gates and 12,096 logic cells. According to the Microchip RTAX-S/SL datasheet, both variants share the same architecture and packages, so the SL is preferred for power-limited spacecraft. Functionally and footprint-wise they are interchangeable for most designs, with the SL trading slight timing margin for lower power.
RTAX1000SL-1CGS624V vs RTAX1000SL-1CGS624EV - which should I choose?
The -V (CGS624V) suffix denotes the standard radiation-tolerant screening flow, while the -EV (CGS624EV) suffix denotes an enhanced/extended screening flow intended for more severe mission environments. Both share the same 624-pin CGA package, 1M gate density, and -1 speed grade, so they are footprint-identical. Choose the EV version for missions with stricter radiation or reliability requirements; choose the V version for standard LEO applications where cost and availability matter.
When should I choose RTAX1000SL over an SRAM FPGA for space?
Choose the RTAX1000SL when your mission requires configuration immunity to single-event upsets: its antifuse fabric cannot suffer configuration upsets, unlike SRAM FPGAs that need external configuration scrubbing and SEU mitigation in the configuration memory. The trade-offs are one-time programmability, lower density (1M gates), and non-reprogrammability. For missions that need in-orbit reconfiguration or very high logic density, SRAM-based rad-hard devices may be preferred instead.
Is RTAX1000SL-1CGS624V suitable for LEO satellite payloads?
Yes, the RTAX1000SL-1CGS624V is well suited to LEO satellite payload processing. Its SEU-hardened registers achieve SEU rates below 10-10 errors per bit-day per the Microchip datasheet, its -55C to +125C rating covers thermal cycling in orbit, and the low-power SL process option reduces static current - important on solar/battery power budgets. Its 1M-gate capacity accommodates payload data formatting, compression front-ends, and telemetry/command interfaces.
What is the best drop-in replacement for RTAX1000SL-1CGS624V?
The best drop-in replacements are same-family Microsemi/Microchip parts in the identical 624-pin CGA footprint: RTAX1000SL-CGS624E (commercial screening of the same die), RTAX1000SL-1CGS624EV (enhanced screening), and RTAX1000S-1CGS624V (non-low-power S variant). All are pin-compatible in the CGA-624 package with identical logic density. Verify the screening suffix matches your mission requirements before substitution, and note the S variant draws higher static power.
Can a cross-brand FPGA replace RTAX1000SL-1CGS624V?
No verified cross-brand drop-in equivalent exists for the RTAX1000SL-1CGS624V. Xilinx Virtex-QV and Microchip/Microsemi RTG4 or PolarFire radiation-tolerant devices serve similar space applications but use different packages, pinouts, and programming technology, requiring board redesign. Radiation-tolerant antifuse FPGAs are a specialized Microsemi/Microchip product line, so replacement is effectively limited to same-family variants. Any cross-brand move requires a PCB and design re-verification cycle.
Where can I download the RTAX1000SL datasheet PDF?
The RTAX1000SL datasheet is available from Microchip Technology's official website as part of the 'RTAX-S/SL and RTAX-DSP Radiation-Tolerant FPGAs' datasheet document (rtaxs_ds2169_v18.pdf on ww1.microchip.com). It covers features, architecture, DC/AC characteristics, packaging, and ordering information for the whole family including the RTAX1000SL-1CGS624V. Distributor sites such as Jotrin, DigChip, and Datasheet4U also mirror the PDF for download.
Where can I find the RTAX1000SL-1CGS624V pinout?
The complete 624-pin pinout for the CGA-624 package is defined in the packaging section of the Microchip RTAX-S/SL datasheet (document rtaxs_ds2169_v18) and in the Libero IDE/SoC design software I/O assignment files. Because this ceramic column grid array has 624 pins across multiple power, ground, configuration, and I/O banks, engineers should extract pin assignments directly from the official datasheet tables and design-tool files rather than from secondary distributor summaries.
Is RTAX1000SL-1CGS624V the same as RTAX1000SL-1CGS624E?
No - they are the same die and package but with different screening flows. The -V suffix on RTAX1000SL-1CGS624V indicates radiation-tolerant (V) screening for space flight, while -E on RTAX1000SL-CGS624E indicates a standard commercial/industrial screening of the same 1M-gate antifuse device in the same CGA-624 footprint. For flight hardware, specify the V-suffix part; the E-suffix part is intended for prototyping and non-flight evaluation.
How does the antifuse technology protect against radiation?
The RTAX1000SL uses one-time-programmable antifuse interconnect, so its configuration is physically permanent metal-to-metal links rather than SRAM bits. Radiation-induced single-event upsets cannot flip configuration data the way they can in SRAM FPGAs, eliminating configuration error modes and external scrubbing circuits. Combined with SEU-hardened flip-flops rated to specified LET thresholds, per the Microchip datasheet this yields SEU rates below 10-10 errors/bit-day without mandatory triple module redundancy.
What are the key specifications of RTAX1000SL-1CGS624V that engineers should know?
Key specifications: 1,000,000 system gates and 12,096 logic cells in digital CMOS; 624-pin ceramic CGA (CCGA) package; -55C to +125C operating range; -1 speed grade; SEU-hardened registers with SEU rate below 10-10 errors/bit-day; embedded SRAM with FIFO control; segmentable clocks, chip-wide highway routing, and carry logic; live-at-power-up, single-chip antifuse configuration. Sourced from the Microchip RTAX-S/SL datasheet and distributor listings as of 2026-09-02.
What design tools support the RTAX1000SL-1CGS624V?
The RTAX1000SL-1CGS624V is supported by Microchip's Libero SoC design suite (successor to Actel Libero IDE), which provides synthesis, place-and-route, timing analysis, and antifuse programming file generation for the RTAX-S/SL family. The same toolchain generates the programming data used at the factory programming house since antifuse devices cannot be field-programmed in-system. Always use a current Libero release with up-to-date device libraries for flight designs to ensure timing accuracy.

Selection Guide

Choose the RTAX1000SL-1CGS624V when you need a flight-proven, radiation-tolerant 1M-gate FPGA with configuration-immune antifuse fabric, low static power, and live-at-power-up operation in a 624-pin ceramic column grid array - typical for LEO payloads, TT&C, and instrument control. Choose the RTAX1000SL-1CGS624EV for missions with stricter screening requirements; choose RTAX1000SL-CGS624E for prototype and non-flight hardware to reduce cost. If power is the dominant constraint, stay on the SL process; if stock availability forces it, the RTAX1000S-1CGS624V offers the same pinout with higher static power. Select a higher-density family member (RTAX2000SL/RTAX4000SL) only if 12,096 logic cells are insufficient, accepting a footprint change. Avoid this family if your mission requires in-orbit reconfiguration - antifuse is one-time programmable.

Key Differentiators

  • Low-power SL process for spacecraft power budgets (vs RTAX1000S-1CGS624V)
  • Enhanced screening option available in same footprint (vs RTAX1000SL-1CGS624EV)
  • Configuration immunity vs SRAM space FPGAs (vs SRAM-based rad-tolerant FPGAs (e.g. Xilinx Virtex-QV class))

Design Notes

The RTAX1000SL is one-time programmable: antifuse programming is performed at a certified programming house, not in the lab or in orbit. Freeze and fully verify the design (timing simulation, radiation-relevant analysis) before submitting the programming file, and use prototype-stage parts (E-suffix, e.g. RTAX1000SL-CGS624E) for hardware validation. There is no field update path - a functional bug after flight-unit programming cannot be patched, only respun at significant cost and schedule impact.

The SL process option significantly reduces static current versus the standard RTAX1000S, which matters on solar/battery-limited spacecraft buses. When estimating mission power, account for the difference if your prototype used an S-variant: the S die draws measurably higher standby current. Obtain per-device static current figures from the Microchip RTAX-S/SL datasheet tables for your voltage and temperature corner (-55C to +125C) rather than extrapolating from commercial FPGA experience.

The CGA-624 (ceramic column grid array) uses solder columns rather than solder balls, providing compliance for CTE mismatch between the ceramic package and the PCB during thermal cycling from -55C to +125C. Design the land pattern to the column geometry specified in the Microchip packaging section (not standard BGA ball pads), and for high-reliability assembly consider underfill or staking per your house assembly standard. Verify reflow profiles against the ceramic package's thermal mass, which exceeds plastic-packaged FPGAs.
