RTAX250SL-CG624PROTO - Rad-Tolerant FPGA 250K Gates | Actel
MPN: RTAX250SL-CG624PROTO ✓ Hoạt độngRTAX250SL-CG624PROTO Tóm tắt
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the total ionizing dose (TID), latch-up, and single-event effects found in orbital and deep-space radiation environments. Within the hierarchy of programmable logic (FPGA -> programmable logic device -> digital IC -> semiconductor), radiation-tolerant FPGAs occupy the high-reliability tier used by satellite payloads, launch vehicles, and spacecraft avionics.
Key features include 250K system gates, embedded SRAM blocks with built-in FIFO control logic, segmentable clocking resources, and chip-wide highway routing inherited from the commercial Axcelerator family. The antifuse architecture is one-time programmable, providing live-at-power-up security and immunity to configuration upset.
Technically, the RTAX-SL family leverages the 0.15 um antifuse CMOS process to achieve 649 MHz toggle-rate-class performance while maintaining low static power. Densities across the family reach up to four million system gates, enabling single-chip integration of complex space-flight logic.
Typical applications include satellite payload data processing, spacecraft bus control, telemetry and telecommand interfaces, and prototyping for RTAX-S/SL flight designs.
Design consideration: use the Microsemi/Aldec flash-based ProASIC3E prototyping adaptor flow (e.g., ACT-H3K-CG624) to validate designs before committing to one-time-programmable flight parts.

Ứng dụng tiêu biểu
RTAX250SL-CG624PROTO phù hợp cho 6 Áp dụngs: Satellite Payload Data Processing, Spacecraft Bus Control and Avionics, Telemetry and Telecommand Interfaces, RTAX Design Prototyping and Emulation, Launch Vehicle and Avionics Electronics, Instrumentation and Sensor Data Acquisition for Space Payloads.
Satellite Payload Data Processing
The RTAX250SL-CG624PROTO fits satellite payload processing where 250K system gates of user logic must survive total ionizing dose and single-event effects in orbit. Its antifuse one-time-programmable architecture is live-at-power-up and immune to configuration memory upset, unlike SRAM FPGAs, and the 649 MHz-class fabric supports high-throughput signal processing chains. In prototyping, the PROTO version is programmed once per design iteration to validate payload datapaths in the flight-representative CG624 package. The trade-off is non-reprogrammability: each logic change requires a new device, which is why teams pair it with the Aldec flash-based ProASIC3E prototyping adaptor before committing flight units.

Spacecraft Bus Control and Avionics
Spacecraft command and data handling (C&DH) and avionics controllers favor the RTAX250SL-CG624PROTO because it delivers deterministic single-chip logic with low static power from a 1.5V core on 0.15 um antifuse CMOS. Embedded SRAM blocks with built-in FIFO control logic buffer telemetry streams, while segmentable clocks support mixed-rate subsystem interfaces. During development, the PROTO device occupies the actual 624-pin CCGA board footprint so bus control logic, power sequencing, and interface timing are validated exactly as flown. Designers should budget for the OTP nature of the part and freeze the design before programming, and follow Microsemi layout guidance for CCGA column-grid soldering and screening.

Telemetry and Telecommand Interfaces
TT&C (telemetry, tracking and command) front-ends use the RTAX250SL-CG624PROTO to implement frame formatting, encoding, and protocol glue logic in a radiation-tolerant, single-chip form factor. With 2,816 logic cells and 649 MHz-class performance, the device easily hosts CCSDS-style framing and serial interfaces, and its chip-wide highway routing simplifies clock distribution across interface domains. In prototyping the PROTO part validates I/O assignments against the 624-pin CCGA pinout used by flight units, reducing board respins. Because antifuse configuration cannot be corrupted by SEU, command decoders stay available at power-up - a key advantage over SRAM-based FPGAs that require external configuration storage.

RTAX Design Prototyping and Emulation
This is the core application of the PROTO suffix itself: validating RTAX-S/SL logic designs before committing one-time-programmable flight devices. Per the Microsemi RTAX-S/SL datasheet, the prototyping methodology uses a footprint-compatible adaptor board and an EDIF netlist and pinout converter for easy migration. The Aldec ACT-H3Ki-CG624 adaptor, based on flash-based ProASIC3E (A3PE3000) technology, is reprogrammable and supports RTAX-S/SL devices up to the 2000S density in the CG624 footprint. The RTAX250SL-CG624PROTO complements this flow by providing a real antifuse device in the target package for final timing, I/O, and board-level verification prior to flight-lot ordering.

Launch Vehicle and Avionics Electronics
Launch-vehicle electronics require logic that is live-at-power-up with no configuration readout time, tolerates vibration-packaged ceramic column grid arrays, and consumes minimal power. The RTAX250SL-CG624PROTO addresses all three: antifuse configuration is present the instant power is applied, the 624-pin CCGA ceramic package suits high-reliability assembly flows, and the 1.5V core on 0.15 um CMOS keeps static power low. Prototyping with the PROTO device allows avionics teams to close timing at 649 MHz-class performance and validate SEU-mitigation schemes (TMR, scrubbing-free datapaths) in real silicon. Substituting the flight CG624V suffix afterwards requires no PCB or pinout changes, protecting program schedule.

Instrumentation and Sensor Data Acquisition for Space Payloads
Scientific instruments on research satellites and deep-space probes rely on the RTAX250SL-CG624PROTO class of devices for front-end acquisition logic: ADC interface sequencing, FIFO buffering using embedded SRAM, and detector timing generation. The RTAX-SL fabric's 250K gates and embedded FIFO control logic consolidate functions that would otherwise need multiple rad-hard ASSPs, shortening payload integration. Prototyping on the PROTO device lets instrument teams iterate detector timing and calibration logic in the exact CG624 mechanical and thermal envelope before flight. Note the OTP constraint - allocate timing margin generously since post-programming changes require a new device - and verify I/O standards against the datasheet DC/AC tables for your sensor bank.

Ghi chú thiết kế
The RTAX250SL is one-time-programmable (antifuse). Once programmed, the device cannot be erased or reworked - a design change requires a new part. Freeze your RTL, close static timing in Libero SoC, and verify I/O assignments before programming. Use the PROTO device for hardware validation and reserve flight suffixes (CG624V/CG624B) for qualification and flight builds.
The 624-pin CCGA uses ceramic column grid array technology, not standard BGA solder balls. Follow the manufacturer CCGA assembly guidelines: controlled solder column volume, X-ray inspection post-reflow, and support for column rework procedures. During prototyping, consider the Aldec ACT-H3Ki-CG624 adaptor (ProASIC3E based) described in the application note Prototyping for RTAX-S and RTAX-SL Devices, which uses an EDIF netlist and pinout converter for design migration.
The RTAX250SL operates from a 1.5V core supply on 0.15 um antifuse CMOS; antifuse FPGAs draw very low static power but supply current scales with active logic and toggle rate at up to 649 MHz-class operation. Estimated: budget core and I/O rails per the datasheet power estimation spreadsheet with your actual utilization rather than worst-case gate count. Decouple VCCA, VCCI, and VCORE rails per the datasheet recommended network; confirm exact I/O bank voltages from the datasheet as they were not captured in this page's verified data.
