RTAX2000S-1CG624PROTO 개요
A radiation-tolerant FPGA is a field-programmable gate array qualified for the space-flight radiation environment. Within the power-management hierarchy of onboard digital electronics, RTAX-S devices sit at the top: one-time-programmable antifuse interconnect makes them live-at-power-up and immune to configuration upsets that affect SRAM-based FPGAs, eliminating the need for external configuration storage.
Key features include total ionizing dose tolerance of 300 krad (functional) and 200 krad (parametric), single-event upset rates below 1E-10 errors per bit-day, up to 684 user I/Os across the family, and embedded memory blocks with optional EDAC protection. Performance reaches up to 350 MHz in system-level designs, based on the commercial Axcelerator architecture.
Architecturally, the RTAX2000S uses a segmented clock structure, chip-wide synchronization outputs, and FIFO control logic integrated into the embedded SRAM, allowing single-chip implementations that would otherwise need glue logic and external memory.
Typical applications include satellite payload processing, spacecraft bus control, telemetry and telecommand interfaces, and orbital instrument controllers, where low power, single-chip reliability, and radiation tolerance are mandatory.
A key design consideration: antifuse FPGAs are one-time programmable, so complete timing closure and in-system verification should be completed before committing a flight lot.
This page adds value beyond the datasheet by synthesizing drop-in family alternatives, packaging options, and application guidance drawn from distributor and manufacturer sources.

일반적인 애플리케이션
RTAX2000S-1CG624PROTO 적합 용도: 6 애플리케이션s: Satellite Payload Data Processing, Spacecraft Bus Control and Telemetry, Telecommand and Security Interface, Orbital Instrument Controller, Launch Vehicle Avionics, Space-Grade RTL Prototyping and Emulation.
Satellite Payload Data Processing
The RTAX2000S-1CG624PROTO fits payload processing because its 2,000,000 equivalent gates and 32,256 logic cells implement high-throughput packet pipelines, compression engines, and DSP filter chains in a single chip, while the 540 kbit embedded SRAM with optional EDAC buffers science data without external memories that would add SEU-sensitive board area. In this role the FPGA sits between the payload sensor chain and the downlink formatter, with its 684 user I/O capability (family max) covering wide parallel sensor interfaces and its up to 350 MHz class performance sustaining real-time throughput. Because the antifuse fabric is live at power-up and immune to configuration upsets, the payload acquires its processing fabric immediately after switch-on during launch-separation events, a critical window in which SRAM FPGAs would still be loading configuration. The trade-off is one-time programmability: the processing pipeline must be frozen and fully verified in the PROTO device before flight-lot programming.

Spacecraft Bus Control and Telemetry
Spacecraft bus controllers benefit from the RTAX2000S's deterministic, live-at-power-up behavior: attitude-control interfaces, mode sequencing, and housekeeping telemetry gather into one antifuse FPGA whose configuration cannot be corrupted by single-event upsets (SEU below 1E-10 errors per bit-day). The segmented clock structure allows multiple independent clock domains - for example a slow telemetry domain and a faster actuator-control domain - while chip-wide synchronization outputs coordinate reset across the spacecraft. The total dose tolerance of 300 krad (functional) comfortably covers typical LEO mission fluences with margin, and 200 krad parametric limits define the end-of-life electrical envelope for worst-case timing analysis. In this application the PROTO-flow part is used on the engineering model and flat-sat units to validate telemetry maps and fault-management state machines before committing to the qualified flow parts.
추천
Telecommand and Security Interface
Telecommand decoders and secure command authentication benefit from the RTAX2000S's nonvolatile antifuse fabric, which holds its configuration without external boot memory that could be observed or corrupted. The device's embedded FIFO control logic in the 540 kbit SRAM smooths burst command ingestion from the receiver front-end, while the wide I/O capability interfaces legacy MIL-STD-style parallel command formats and modern serial links. The 300 krad functional total dose rating supports multi-year GEO missions, and low static power from the CMOS antifuse process minimizes load on the power bus during eclipse. Designers typically implement the command decoder in the PROTO part during EGSE integration testing, exploiting the Aldec ACT-H3Ki-CG624 flash-based prototyping adaptor for iterative test-case development, then program the final decoder image into flight parts. One-time programmability here is an assurance benefit: the deployed command path cannot be reconfigured in flight.
추천
Orbital Instrument Controller
Science instruments on orbital platforms - imagers, spectrometers, and particle detectors - use the RTAX2000S-1CG624PROTO as the sequencing and acquisition controller. Its 32,256 logic cells generate precise exposure and readout timing, and the embedded SRAM blocks with EDAC stage acquisition data ahead of the mass-memory unit. The 350 MHz-class fabric performance supports high-rate ADC deserialization and front-end filtering, while the 684 user I/O ceiling accommodates multi-channel detector arrays. Radiation characteristics are decisive here: 300 krad functional TID covers the accumulated dose behind typical instrument shielding, and sub-1E-10 errors/bit-day SEU rates keep acquisition integrity high without triple-module redundancy on every register. Engineering-model instruments are exercised on the PROTO device to tune timing closure; the identical die and footprint of the qualified variants allow the flight board to be unchanged. The main design consideration is planning the I/O bank assignment early, since antifuse devices cannot be re-routed after layout freeze.

Launch Vehicle Avionics
Launch-vehicle avionics demand both radiation hardness for the belt-transit trajectory and immediate availability at power-up - the RTAX2000S delivers both, with live-at-power-up antifuse configuration and 300 krad functional total dose tolerance. Flight sequencing, telemetry encoding, and safe-and-arm interface logic consolidate into a single CCGA-624 ceramic package whose column-grid construction withstands the thermal and mechanical vibration profile of launch. The -1 speed grade provides adequate timing margin at spacecraft-typical clock rates while maximizing radiation and power headroom, and low quiescent power from the CMOS antifuse process suits battery-limited ascent phases. Programs use the PROTO-flow part through qualification testing - vibration, thermal-vacuum, and EMI campaigns - because its identical die and package guarantee representative electrical behavior, then release flight boards populated with the qualified flow equivalent. Design reviews should verify worst-case timing at 200 krad parametric corners before flight-lot programming.

Space-Grade RTL Prototyping and Emulation
Before committing one-time-programmable antifuse devices, teams validate RTAX2000S designs on reprogrammable silicon. The jointly supported Microchip-Aldec flow places a flash-based ProASIC3E device - such as the A3PE3000 - on the Aldec ACT-H3Ki-CG624 adaptor, whose BGA balls mimic the CG624 footprint so the adaptor assembles directly on the target board in the RTAX chip position, supporting RTAX-S/SL designs up to the 2000S density. This enables full in-system RTL iteration, embedded-processor bring-up, and board-level timing exploration without consuming scarce antifuse parts. The RTAX2000S-1CG624PROTO then serves as the intermediate step: it is programmed with the frozen design to perform final system validation on the true silicon, verifying timing, I/O behavior, and power that the ProASIC3E emulation approximates. The trade-off is time: each PROTO device supports one programming pass, so complete simulation and STA sign-off should precede programming.

설계 노트
The RTAX2000S is one-time programmable: each blown antifuse device is consumed. Achieve full timing closure, complete gate-level simulation, and static timing sign-off in Libero before programming any unit. For iterative debugging, use the Aldec ACT-H3Ki-CG624 prototyping adaptor (A3PE3000 ProASIC3E flash die on a CG624-mimicking footprint) so board hardware can be exercised with reprogrammable silicon while the PROTO parts are reserved for final validation.
The CCGA-624 ceramic column grid array is a mechanical-compliance package: column geometry absorbs CTE mismatch between the ceramic package and the FR-4 board, but column attachment quality is critical. Follow Microchip/Microsemi CG624 land-pattern and reflow guidance from the datasheet package section, inspect columns before assembly, and avoid board flexure near the device during handling. X-ray or acoustic inspection after reflow is standard practice for column-grid packages in space hardware.
Estimated: plan core and I/O power using Libero smart power reports rather than family-average figures, since utilization in a 32,256 logic-cell design dominates current draw. The antifuse fabric has no configuration current at power-up (live at power-up), simplifying inrush analysis versus SRAM FPGAs - but I/O bank pre-drivers and clock-tree activity still create switching current that must be decoupled per the datasheet power-supply recommendations.
With up to 684 user I/Os available in the family and many user-definable pins in CG624, finalize I/O bank assignment early and honor bank voltage groupings. Route clock nets on the segmentable clock resources instead of general routing, and use chip-wide synchronization outputs for system reset coordination. Verify worst-case timing at the 200 krad parametric dose corner, not just the beginning-of-life corner, before releasing the flight design.
