RTAX2000S-CG1152V 概要
A radiation-tolerant FPGA is a programmable logic device qualified for space-flight environments, where exposure to cosmic rays and trapped-particle radiation would upset or degrade commercial silicon. Within the semiconductor hierarchy, it sits under FPGA -> programmable logic IC -> digital integrated circuit -> semiconductor. The RTAX-S/SL family was developed from Microsemi (Actel) commercial Accelerator AX technology and is a standard choice for spacecraft payload computing, telemetry, and bus electronics.
Key features include high-density two-million-gate capacity, embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic. As an anti-fuse, one-time-programmable device it is live-at-power-up, requiring no external configuration flash, which is a decisive advantage in single-string space systems where a configuration read failure would be mission-ending.
Architecturally, the RTAX2000S combines a low-power flash/anti-fuse CMOS process with a fine-grained Sea-of-Modules fabric. Radiation tolerance is achieved through the anti-fuse programming technology, which is inherently immune to configuration upsets, while the fabric is hardened against total ionizing dose (TID). Designers implement triple-module redundancy in logic where single-event effects must be mitigated at the application level.
Typical applications include satellite payload data processing, spacecraft on-board computers, radiation-hardened bus interfaces, sensor-data acquisition in orbital platforms, and secure aerospace communication systems, where single-chip logic density and power efficiency at 1.5V core are critical system drivers.
Design consideration: anti-fuse programming is one-time, so functional verification must be completed on a reprogrammable prototyping adaptor (for example Aldec flash-based ProASIC3E adaptors) before flight-unit programming; the prototype device mirrors the RTAX footprint for board-level test.

主な用途
RTAX2000S-CG1152V の用途: 6 件s: Satellite Payload Data Processing, Spacecraft On-Board Computer (OBC) Logic, Radiation-Hardened Bus and Interface Electronics, Instrument Sensor Data Acquisition, Secure Aerospace Communication Systems, Prototyping and Emulation of Space Flight Designs.
Satellite Payload Data Processing
The RTAX2000S-CG1152V fits payload data-processing chains where 2,000,000 system gates of reconfigurable logic must run continuously in a radiation environment. With 32,256 logic cells, embedded SRAM blocks with built-in FIFO control, and 684 user I/O, it implements high-throughput parallel datapaths, format converters, and compression engines on a single chip. Its anti-fuse fabric is live at power-up, removing external configuration devices that add failure modes in orbit. Placed in the metal-sealed CG1152 ceramic package rated -55C to +125C, the device withstands launch vibration and orbital thermal cycling, while the 1.5V nominal core keeps static power low within the spacecraft power budget.

Spacecraft On-Board Computer (OBC) Logic
In spacecraft on-board computers, the RTAX2000S-CG1152V implements bus interfaces (MIL-STD-1553, SpaceWire), memory controllers, watchdog and health-monitoring logic around a processor core. The segmentable clock structure and chip-wide highway routing support multiple independent clock domains typical of command/telemetry subsystems, while dedicated carry logic accelerates CRC and error-correction arithmetic. Because the device is radiation-tolerant and live at power-up, reset behavior is deterministic - a critical property for autonomy. Designers combine the fabric with application-level triple-module redundancy; the CG1152 hermetic package and 684 I/O provide the connectivity and environmental margin required for multi-year missions.
おすすめ
Radiation-Hardened Bus and Interface Electronics
The RTAX2000S-CG1152V is well suited to interface and bridge electronics that connect spacecraft payloads, instruments, and avionics to the vehicle bus. With 684 inputs and 684 outputs, a single device terminates wide parallel instrument interfaces, LVDS-style links via supported I/O standards, and redundant bus masters. Embedded SRAM with FIFO control buffers asynchronous data-rate matching between instruments and downlink chains without external FIFO chips, reducing part count and reliability risk. Operating from a 1.5V nominal core across -55C to +125C, and packaged in the hermetic CG1152 ceramic CBGA, the device maintains interface integrity under radiation and thermal stress.
おすすめ
Instrument Sensor Data Acquisition
Scientific instruments on orbital platforms - imagers, spectrometers, particle detectors - generate high-volume data streams that the RTAX2000S-CG1152V conditions, sequences, and packetizes. Its 32,256 logic cells implement multichannel timing generators, ADC framing logic, and real-time co-adders, while embedded SRAM FIFOs absorb burst data before downlink. The device's deterministic live-at-power-up behavior ensures acquisition begins as soon as instrument power arrives, without configuration latency. The CG1152 metal-sealed ceramic package protects die integrity through launch loads and vacuum thermal cycles, and low 1.5V-core power helps fit within the strict power allocation typical of instrument electronics boards.
おすすめ
Secure Aerospace Communication Systems
Secure communication payloads and encryption front-ends benefit from the RTAX2000S-CG1152V's one-time-programmable anti-fuse fabric: once programmed, the configuration physically resides in the silicon and cannot be read back or disturbed by radiation-induced configuration upsets, a meaningful security property absent from SRAM-based FPGAs. The 2,000,000-gate capacity accommodates cipher cores, key-handling logic, and multiple redundant channel engines simultaneously. Dedicated carry logic accelerates arithmetic in stream-cipher datapaths, and 684 user I/O support wide, redundant RF-chain interfaces. The hermetic CG1152 package with -55C to +125C rating matches ground-station and space-segment environmental requirements.
おすすめ
Prototyping and Emulation of Space Flight Designs
Because RTAX-S anti-fuse devices are programmed once, the design flow relies on reprogrammable prototyping. The Aldec ACT-H3Ki-CQ256-class adaptors pair flash-based Microchip ProASIC3E technology with an RTAX-compatible footprint, allowing the prototype adaptor to mount directly in the RTAX2000S-CG1152V board location with no PCB change. Engineers iterate RTL and timing in flash, then transfer the verified design to the flight RTAX2000S. XAIPART lists the RTAX2000S-1CG1152PROTO device specifically designated for this prototyping flow, plus the same-family A3PE/M1AFS ProASIC/flash parts that populate the adaptors, enabling full board-level emulation before committing a flight unit.

設計ノート
RTAX-S anti-fuse FPGAs are one-time programmable. Never program the flight RTAX2000S-CG1152V before functional verification: validate the design on a reprogrammable prototyping adaptor (Aldec ACT-H3Ki series using flash ProASIC3E technology) that mounts directly in the RTAX footprint, then transfer the verified netlist to the flight device. Once programmed, an error requires scrapping a several-thousand-dollar space-grade part and repeating lot traceability.
With up to 684 outputs switching in a 1152-ball BGA, simultaneous switching noise is the dominant signal-integrity risk. Separate I/O bank supplies with dedicated planes, place decoupling capacitors beneath the CG1152 body on the opposite side of the board, and stagger output switching by assigning related signals to adjacent balls within a bank. Follow the RTAX-S/SL datasheet I/O banking rules - mixing incompatible I/O standards in one bank degrades noise margins.
The RTAX2000S core runs from a 1.5V nominal supply, which keeps static power low - a key family advantage per Microchip. Estimated: size the core rail for the datasheet ICC figures at your clock frequency plus I/O current for your termination scheme; rail sag below the 1.5V nominal minimum under switching load is a common cause of marginal timing in flight builds. Add bulk capacitance at the VRM in addition to per-bank decoupling.
The CG1152 is a 1152-terminal ceramic CBGA requiring a matched 1.0 mm-pitch land pattern per the datasheet package drawing and controlled reflow profile; ceramic packages have different CTE than FR-4, so underfill or compliant-layer decisions should follow your space-qualified assembly process. Verify ball-map assignments in Libero Designer before routing and reserve a few spare balls near each bank for engineering changes.
