Typical Applications

RTAX2000SL-LG624V is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Bus Control and Avionics, Telemetry, Tracking and Command (TT&C), Deep-Space Science Instruments, Launch Vehicle and Reentry Systems, New Space LEO Constellations.

✈️

Satellite Payload Data Processing

The RTAX2000SL-LG624V fits payload data processing because its ~2,000,000 equivalent gates and 32,256 logic cells provide the fabric width needed for on-board image compression, channel coding, and encryption, while its antifuse configuration is immune to SEU-induced configuration corruption - eliminating the configuration-memory scrubbing burden of SRAM FPGAs. The 649 MHz-class fabric supports high-throughput parallel datapaths on a 1.5V nominal core, keeping power within typical payload allocations. In use, the device implements CCSDS-compliant encoders, framing, and lossless compression between sensor front ends and downlink modems. The trade-off is one-time programmability: prototypes must be validated on ProASIC3E-based adaptors (e.g., RTAX2000S-CG624PROTO) before flight units are programmed, as antifuse programming is irreversible and flight rework is impossible.

🛰️

Spacecraft Bus Control and Avionics

For spacecraft bus controllers, attitude determination, and platform avionics, the RTAX2000SL-LG624V offers live-at-power-up operation with no boot device - a single-chip solution that reduces parts count and failure modes on the most reliability-critical board. Its RTAX-SL antifuse fabric holds configuration through single-event effects, while -55C to +125C operation covers launch transients and eclipse thermal cycling. Engineers typically implement MIL-STD-1553 or SpaceWire interfaces, watchdog logic, and mode-control state machines in the 32,256 logic cells. Performance consideration: since the device is one-time programmable, interface IP must be timing-verified in Libero SoC on the standard speed grade, or the '-1' variant (RTAX2000SL-1LG624V) selected for margin; the shared LG624 footprint lets one PCB support either grade without redesign.

🌐

Telemetry, Tracking and Command (TT&C)

The RTAX2000SL-LG624V suits TT&C subsystems where the logic must survive years of accumulated total ionizing dose and frequent single-event upsets without service. Its embedded SRAM blocks with built-in FIFO control logic buffer telemetry frames and command queues, while chip-wide highway routing and segmentable clocks help isolate the slow, safety-critical command path from faster telemetry processing domains. Typical implementations include PCM frame formatters, command decoders, and watchdog/failsafe logic running at modest clock rates but requiring zero configuration-error probability. The 1.5V core minimizes static draw during eclipse when the platform runs on battery. Design consideration: protect I/O banks with radiation-hardened line drivers or RC filtering, and verify latch-up limits per the Microchip RTAX-S datasheet characterization for your orbital environment.

🔭

Deep-Space Science Instruments

Deep-space missions impose extreme radiation and strict power budgets, and the RTAX2000SL-LG624V addresses both: the antifuse fabric has no configuration upset mechanism, and the RTAX-SL low-static-power optimization on a 0.15 um 1.5V process conserves energy over multi-year cruises. With ~2M gates, the device implements instrument front-end sequencing, high-rate ADC interface glue, on-board histogramming, and lossy-on-demand compression for spectrometers, imagers, and particle detectors. The 624-pin CLGA provides the I/O count to aggregate multiple sensor channels on one chip, reducing harness mass. Because flight devices are programmed once, instrument teams use the Aldec/Microchip flash-based prototyping adaptor to validate FPGA code against real instrument hardware before committing flight parts, then program the full mission lot from a single verified design database.

🚀

Launch Vehicle and Reentry Systems

Launch-vehicle avionics demand determinism at power-up and immunity to the intense radiation and vibration of ascent - both strengths of the RTAX2000SL-LG624V. Its live-at-power-up antifuse configuration removes boot latency from flight-critical timelines, and -55C to +125C operation plus a rugged 624-pin CLGA soldered interconnect suit booster flight computers, separation sequencing, and flight-termination interfaces. Designers map redundant sensor voting and dual-string control logic across the 32,256 logic cells, exploiting SEU-immune configuration so that only transient upsets in registers (handled by design-level TMR) need consideration. Performance trade-off: fabric speed is capped by the selected speed grade, so time-critical control loops should be timing-verified at worst-case temperature; the RTAX2000SL-1LG624V variant on the same footprint provides additional timing margin when needed.

📡

New Space LEO Constellations

LEO constellations balance rad-tolerance with cost at scale, and the RTAX2000SL-LG624V serves the payload and gateway side of that equation where SEU-immune configuration justifies antifuse cost. At ~2M gates and 649 MHz-class performance, one device replaces multiple glue ASICs in software-defined radio payload chains, implementing DDC/DUC filters, framing, and interfacing to high-speed ADC/DACs. The single-chip, no-configuration-flash architecture simplifies qualification and removes a radiation-sensitive part from the BOM. Constellation operators often standardize one LG624 PCB across payload revisions, populating RTAX1000SL-LG624V for cost-down variants and RTAX2000SL-1LG624V for high-throughput beams. Planning note: antifuse one-time programming requires disciplined design freeze and lots programming under ESD-controlled conditions; budget prototype cycles on ProASIC3E hardware before the flight production run.

What is the RTAX2000SL-LG624V?
The RTAX2000SL-LG624V is a Microchip Technology (formerly Actel/Microsemi) radiation-tolerant FPGA from the RTAX-SL family with approximately 2,000,000 equivalent system gates, 649 MHz maximum performance, and a 1.5V nominal core supply. It is packaged in a 624-pin CLGA (LG624) and uses one-time-programmable antifuse technology that is live at power-up, making it intended for space-flight systems. According to the Microchip RTAX-S/SL datasheet, the family is derived from the commercial Axcelerator architecture.
What is the price of RTAX2000SL-LG624V?
Space-grade RTAX2000SL-LG624V units are high-cost, low-volume devices; XAIPART lists pricing from $2,200.00 per unit at quantity 1, scaling to approximately $1,760.00 at quantity 1000 as of 2026-09-02. Because pricing for radiation-tolerant FPGAs fluctuates with lot date codes and stock source (franchised vs independent distributors), request a formal quote for large quantities and verify the exact speed grade and package suffix before ordering.
Where can I buy RTAX2000SL-LG624V online?
You can request a quote for RTAX2000SL-LG624V directly on XAIPART, which sources space-grade inventory with traceability documentation. Authorized channels for Microchip FPGA space products include Microchip direct sales and franchised space-component distributors; stock is also listed by brokers such as Jotrin Electronics and VEKEMO. For flight programs, always purchase with full manufacturer traceability certificates (COC, SCD) rather than untraceable broker stock, as mission assurance requires documented lot genealogy.
What is the difference between RTAX2000SL-LG624V and RTAX2000SL-1LG624V?
The '1' in RTAX2000SL-1LG624V denotes a faster speed grade than the standard RTAX2000SL-LG624V. Both parts use the identical die, 1.5V supply, antifuse RTAX-SL architecture, and 624-pin CLGA (LG624) package, making them electrically drop-in compatible; the difference is timing performance, with the '-1' grade supporting the highest clock rates. Choose the standard grade to reduce cost when your design timing closes comfortably, and the '-1' grade for maximum frequency margin per the Microchip RTAX-S/SL datasheet speed-grade tables.
What is the best drop-in replacement for RTAX2000SL-LG624V?
The best drop-in replacement is RTAX2000SL-1LG624V: the same RTAX2000SL die in the same 624-pin CLGA (LG624) footprint with only a faster speed grade, giving 100% pin compatibility. Within the family, RTAX2000S-1LG624V is another same-package option, and RTAX1000SL-LG624V / RTAX1000S-1LG624V are pin-compatible smaller-density alternatives if your design fits 1M gates. No cross-brand pin-compatible replacement exists in the web data; RTAX-S antifuse FPGAs are effectively sole-source to Microchip.
Is there a cross-brand equivalent for the RTAX2000SL-LG624V?
No direct cross-brand, pin-compatible equivalent for the RTAX2000SL-LG624V was found in the verified web data. Radiation-tolerant antifuse FPGAs are a niche market dominated by Microchip (RTAX-S/SL) with no other manufacturer offering a pin-to-pin compatible 624-pin CLGA device. The nearest functional alternatives, such as Xilinx Virtex-QV or Microchip RTG4 flash-based FPGAs, use entirely different packages and architectures and require a full PCB redesign, so they are not drop-in replacements.
Where can I download the RTAX2000SL datasheet PDF?
You can download the official RTAX-S/SL and RTAX-DSP Radiation-Tolerant FPGAs datasheet PDF from Microchip's document server at ww1.microchip.com (file rtaxs_ds2169_v18.pdf), which covers features, options, and ordering information for the entire RTAX-S/SL family including the RTAX2000SL-LG624V. The same document is linked from the Microchip RTAX2000SL product page at microchip.com/en-us/product/RTAX2000SL. Avoid third-party datasheet mirrors, as they may host outdated revisions.
What are the key specifications of RTAX2000SL-LG624V engineers should know?
The RTAX2000SL-LG624V is a radiation-tolerant antifuse FPGA with approximately 2,000,000 equivalent gates, 32,256 logic cells, 21,504 CLBs, up to 649 MHz system speed, a 1.5V nominal core supply, and a 624-pin CLGA package. It operates from -55C to +125C, is fabricated on a 0.15 um CMOS process, includes embedded SRAM with FIFO control logic, and is live at power-up with no external configuration device. These figures come from Microchip and distributor datasheets.com parametric data.
Why is the RTAX2000SL immune to configuration upsets in orbit?
The RTAX2000SL uses antifuse programming elements: unprogrammed antifuses are open circuits, and programmed ones are permanent, nanometer-scale conductive links. Because the configuration is physically burned in and contains no volatile storage cells, single-event upsets cannot flip configuration bits the way they can in SRAM FPGAs. According to the Microchip RTAX-S datasheet, this enables true single-chip, live-at-power-up operation with no configuration flash, eliminating a common failure point in space-flight systems and reducing board area and power.
How do I prototype a design for RTAX2000SL before committing flight parts?
Use the Microchip/Aldec prototyping flow: since antifuse RTAX devices are one-time programmable, designs are validated on flash-based ProASIC3E FPGAs mounted on an RTAX prototyping adaptor, which mimics RTAX timing and I/O behavior. Microchip's Libero SoC design suite compiles the same netlist target, and devices such as RTAX2000S-CG624PROTO exist specifically for this purpose. Only after timing closure and verification on the prototype should you program flight-unit antifuse devices, as programming is irreversible.
What power supply design is needed for the RTAX2000SL-LG624V?
The RTAX2000SL requires a nominal 1.5V core supply; I/O bank voltages are configured per design and detailed in the datasheet's power section. Because antifuse FPGAs draw very low static power, a radiation-tolerant linear regulator or small DC-DC converter is typically sufficient for the core rail. Add bulk and local decoupling capacitance at each supply pin group per the Microchip RTAX-S datasheet layout guidance, and verify inrush and sequencing against your platform's power budget during thermal-vacuum testing.
Is the RTAX2000SL-LG624V still in production?
Yes, the RTAX2000SL-LG624V is listed as an active product on Microchip's official RTAX2000SL product page as of 2026-09-02. Microchip continues to support the RTAX-S/SL space-flight family for both new designs and legacy program sustainment, and distributor parametric data was last updated 29-APR-2024 on datasheets.com. For long-duration space programs, confirm MIL-PRF-38535 QML flow availability and projected end-of-life via Microchip's space products team and the DLA cross-reference guide.
RTAX2000SL vs RTAX250SL in the LG624 package - which should I choose?
Choose the RTAX2000SL-LG624V when your design needs roughly 2 million equivalent gates (32,256 logic cells); choose the RTAX250SL-LG624V when your design fits the smaller RTAX250SL density, which lowers cost and typically reduces power. Both share the same 624-pin CLGA footprint within the RTAX-SL family, so PCB redesign is not needed when moving between them. Verify that your Libero SoC timing report closes on the smaller device's routing resources, since lower density means higher utilization pressure at the same 649 MHz-class speed targets.
What is the operating temperature range of RTAX2000SL?
The RTAX2000SL family operates from -55C to +125C according to distributor data for the RTAX2000SL-1LG624V variant published by Microchip USA. This military-temperature envelope supports launch environments, eclipse heating/cooling cycles, and proximity to heat-generating payloads. Junction temperature margins should be validated with mission-specific thermal analysis, since orbital thermal cycling plus radiations-induced effects can shift timing; consult the Microchip RTAX-S/SL datasheet derating tables for speed-versus-temperature characterization.
Hey Google, what can replace the RTAX2000SL-LG624V?
The closest same-footprint replacements are RTAX2000SL-1LG624V (identical die and 624-pin CLGA package, faster speed grade) and the RTAX2000S-1LG624V. If your logic fits a smaller device, RTAX1000SL-LG624V and RTAX1000SL-1LG624V use the same LG624 footprint with half the gate density. There is no cross-brand pin-compatible equivalent in verified web data; any move to Xilinx Virtex-QV or Microchip RTG4 requires a new PCB. All replacements remain Microchip antifuse, one-time-programmable devices.

Selection Guide

Choose RTAX2000SL-LG624V when your space-flight design needs ~2M gates of SEU-immune antifuse logic with low static power and the standard speed grade closes timing in Libero SoC - the cost-effective choice for payload processing, TT&C, and bus avionics. Select RTAX2000SL-1LG624V (same die, same 624-pin CLGA footprint) when timing margin is tight at -55C/+125C extremes. Choose RTAX2000S-1LG624V only if SL stock is unavailable and slightly higher static power is acceptable. Step down to RTAX1000SL-LG624V or RTAX250SL-LG624V on the same footprint when logic utilization allows, cutting cost while preserving the PCB. Honest limitation: RTAX antifuse devices are one-time programmable and sole-sourced by Microchip - if your program requires reprogrammability in flight or a second supplier, no drop-in alternative exists and a full redesign (e.g., RTG4 flash FPGA) is required.

  • Double the density of same-footprint alternatives (vs RTAX1000SL-LG624V)

Design Notes

Antifuse FPGAs are one-time programmable: a programming error or unverified design permanently consumes a flight device costing thousands of dollars. Establish a strict design-freeze gate - Libero SoC timing closure at worst-case temperature/voltage, functional simulation, and hardware validation on a ProASIC3E-based prototyping adaptor (e.g., RTAX2000S-CG624PROTO) - before any RTAX2000SL-LG624V device reaches the programmer. Program flight units in an ESD-controlled area with traceable programmer calibration records, and retain one spare programmed unit per design revision for failure investigation.

The RTAX2000SL uses a 1.5V nominal core supply with very low static power - an advantage over SRAM FPGAs, but you must still budget dynamic power for the 649 MHz-class fabric when datapaths toggle at high rates. Estimate dynamic power in Libero's SmartPower using realistic switching activity from simulation, then derate for radiation-induced threshold shifts. Provide local decoupling (bulk plus 0.1 uF ceramics) at each supply pin group per the Microchip RTAX-S datasheet, and verify inrush and sequencing against the platform EPS during thermal-vacuum testing.

The 624-ball CLGA requires careful board design: use microvia-in-pad or the recommended land pattern from the RTAX-S package data, maintain controlled impedance on high-speed I/O banks, and route JTAG/programming access so flight programming is possible after assembly. Because antifuse configuration removes the need for configuration flash, keep the reclaimed board area for decoupling and guard-trace isolation of sensitive analog I/O. X-ray inspect solder joints after reflow - collapsed balls on CLGA packages are a common hidden defect in space assemblies.

While RTAX configuration is SEU-immune, user flip-flops are not: apply triple-module redundancy (TMR) to control state machines and use the device's segmentable clock domains to isolate safety-critical logic from high-activity datapaths. Mitigate SET on I/O with filtering or threshold buffering per your mission's radiation design margin (RDM) policy, and validate SEFI-free operation with beam testing on qualification lots.
