RTAX2000S-1CQ256V Übersicht
A radiation-tolerant FPGA is a programmable logic device qualified for the space-flight environment, where cosmic rays and trapped protons threaten SRAM-based logic. Unlike SRAM FPGAs, the RTAX-S family uses one-time-programmable antifuse interconnect, giving a true single-chip form factor (no external configuration flash), live-at-power-up operation, and intrinsic immunity to configuration upset - key reasons it is the FPGA of choice for space designers.
Key features include the 2M-gate fabric with embedded SRAM blocks that include built-in FIFO control logic, segmentable clock resources, and chip-wide highway routing inherited from the commercial Axcelerator family. The -1 speed grade and C (standard) temperature/quality grade designation target space flight programs where flight heritage and established documentation dominate procurement decisions.
Architecturally, the RTAX2000S descends from the Actel Axcelerator architecture, combining fine-grain logic modules with dedicated embedded memory and high-performance routing. Because configuration data is hard-wired via antifuses at programming time, the device boots functional logic within microseconds of power application - a decisive advantage over SRAM FPGAs that require an external configuration source vulnerable to SEU.
Typical applications include satellite payload data processing, spacecraft bus control and telemetry, deep-space probe avionics, and launch-vehicle electronics. The Aldec ACT-H3Ki-CQ256 adaptor enables reprogrammable flash-based prototyping (ProASIC3E) in the same footprint before committing to one-time programmable flight parts.
Design consideration: antifuse FPGAs are OTP - validate the design fully in the Aldec prototype flow before programming flight units.

Typische Anwendungen
RTAX2000S-1CQ256V ist geeignet für 6 Anwendungs: Satellite Payload Data Processing, Spacecraft Bus Control and Telemetry, Deep-Space Probe Avionics, Launch Vehicle Electronics, Space-Grade Prototyping and Emulation, Radiation Test and Research Platforms.
Satellite Payload Data Processing
The RTAX2000S-1CQ256V fits satellite payload processing because its 2,000,000 equivalent gates and 21,504 CLBs implement framing, compression, and channel-coding datapaths, while embedded SRAM blocks with built-in FIFO control absorb rate mismatches between sensors and downlink. The antifuse fabric is immune to configuration upset, so no scrubbing controller or external configuration flash is needed in the payload chain, reducing parts count and failure modes. Placed between payload sensors and the telemetry formatter, the -1 speed grade closes timing on wide parallel buses, and the single-chip, live-at-power-up design simplifies redundancy management in orbit.
Empfohlen
Spacecraft Bus Control and Telemetry
Spacecraft bus controllers benefit from the RTAX2000S-1CQ256V's live-at-power-up behavior: attitude, power, and housekeeping logic is functional within microseconds of power application, with no configuration load time or boot device to fail. The 21,504 CLBs accommodate multiple MIL-STD-1553, UART, and custom telemetry interfaces implemented in a single device, while segmentable clocks allow independent clock domains for bus interfaces and mission logic. Its radiation-tolerant CMOS fabric keeps static power low - critical for eclipse-mode battery budgets - and the CQ256 ceramic package withstands the screening environment required for bus avionics assemblies.

Deep-Space Probe Avionics
Deep-space missions face severe galactic-cosmic-ray flux where SRAM FPGA configuration upset rates become mission-limiting; the RTAX2000S-1CQ256V addresses this with inherently SEU-hard antifuse interconnect that cannot lose its configuration. The 2,000,000-gate capacity with an additional 250,000 ASIC gates supports instrument sequencing, science-data packetization, and fault-management logic on one chip. Chip-wide highway routing distributes clocks and control across the die with low skew for instrument synchronization. Flight heritage across the RTAX-S family, recognized in ESA documentation and ESCC REP 010 for the S variant, simplifies qualification reviews for probe-class programs.
Empfohlen
Launch Vehicle Electronics
Launch-vehicle flight computers and sequencers require deterministic power-up behavior and tolerance to vibration and radiation environments; the RTAX2000S-1CQ256V meets these with its one-time-programmable antifuse fabric (no configuration memory to upset) and hermetic 256-pin ceramic CQFP package. The -1 speed grade closes timing on safety-critical sequencing and abort-detection logic, while the 21,504-CLB capacity integrates redundant-channel voting and bus interfaces in a single device, reducing board count. Live-at-power-up operation guarantees the sequencer is active the instant flight batteries engage, with zero boot latency.
Empfohlen
Space-Grade Prototyping and Emulation
Because the RTAX2000S-1CQ256V is one-time programmable, flight designs must be validated on reprogrammable silicon first. Aldec's ACT-H3Ki-CQ256 adaptor board supports designs targeting the RTAX2000S/SL, mounting flash-based Microchip ProASIC3E technology in a footprint compatible with the RTAX device location - it assembles directly in the RTAX position with no target-board changes. This flow lets teams iterate RTL and timing in the lab, then commit to OTP flight parts with high confidence. The same package compatibility means signal-integrity measurements and board bring-up results transfer directly to the flight unit.
Empfohlen
Radiation Test and Research Platforms
Research institutions characterizing single-event effects use the RTAX2000S-1CQ256V as a reference device because its antifuse fabric provides a stable, upset-immune control fabric for building SEU test circuits, monitors, and readout electronics for beam-line campaigns. The 2,000,000-gate capacity hosts arrays of configurable test structures alongside error-detection logic, and embedded SRAM with FIFO control streams results off-chip during irradiation. Its documented heritage and public Microchip datasheet (rtaxs_ds2169) provide the traceable baseline data needed for publications and ESA-style qualification reports.

Designhinweise
The RTAX2000S is one-time programmable: antifuses are blown permanently at programming. Never program flight units until the design has closed timing in Libero and been validated on reprogrammable silicon - Aldec's ACT-H3Ki-CQ256 adaptor fits the RTAX footprint and uses flash-based ProASIC3E for this purpose. Also note the manufacturer's package-compatibility warning: RTAX2000S/SL and RTAX2000D/DL are NOT pin compatible in the CQ352 package type, so never assume family-wide pinout uniformity across CQFP variants.
Ceramic CQFP packages on space boards typically use hand-soldered or socketed assembly with relatively long leads; keep flight-critical clocks and strobes away from package corners where lead inductance dominates, and use series termination on all outputs leaving the package. The RTAX-S segmentable clock resources let you localize high-speed clocking to one region - use them to avoid distributing fast clocks chip-wide through the highway routing when only a subsystem needs them.
Estimated: RTAX-S antifuse FPGAs are noted by Microchip for low-power consumption and true single-chip operation (no external configuration device drawing current at boot). Because exact core/I/O current figures are not quoted in this page's verified data, obtain the ICC numbers from the rtaxs_ds2169 datasheet power chapter and budget them against the spacecraft power bus before layout; this also determines the decoupling network per power rail.
Plan the CQ256 land pattern per the package drawing in the Microchip datasheet and confirm compatibility of your board's footprint with the SL variant if a second-source substitution (e.g., RTAX2000SL-1CQ256V) may be populated later - same-footprint sourcing flexibility is one of the main advantages of this package choice. Include test access to all configuration/programming pins, since antifuse programming equipment interfaces through dedicated pins that must remain reachable in-circuit.
