RTAX250S-1CQ208V 개요
A radiation-tolerant FPGA is a programmable logic device qualified and hardened for space-flight environments, where high-energy particles cause single-event effects (SEE) and total ionizing dose (TID) degradation. Within the power/processing hierarchy of a spacecraft avionics stack, the RTAX-S family sits alongside rad-hard ASICs and rad-hard microcontrollers as a single-chip programmable fabric for mission-critical digital logic, bridging the gap between fully custom silicon and commercial FPGAs.
Key features of the RTAX250S include true single-chip operation, live-at-power-up functionality, and low static power consumption - attributes Microchip identifies as the reasons RTAX-S is widely selected by space system designers. The CMOS process enables fast, reliable operation, while the ceramic CQ208 hermetic package supports the thermal and reliability demands of launch and on-orbit operation.
Architecturally, the RTAX250S belongs to the RTAX-S/SL family (per datasheet ds2169), which is prototyped in commercial Axcelerator devices through Microchip application note AC170 before flight-unit programming. The 0.93 ns combinatorial delay supports moderate-speed datapath, telemetry, and control functions. Designs may also target the alternate 30,000 ASIC-gate organization documented for the RTAX250S-CQ208V variant.
Typical applications include satellite on-board data handling, payload telemetry formatting, attitude control interface logic, spacecraft bus communications bridges, and launch-vehicle avionics - anywhere live-at-power-up logic and radiation tolerance at 250k-gate scale are required.
Design consideration: RTAX-S devices require programming via Microchip FlashPro tooling and are typically prototyped on equivalent commercial Axcelerator parts, so plan the prototype-to-flight flow early in the program. Carefully derate SEU margins per the RTAX-S datasheet reliability sections.

일반적인 애플리케이션
RTAX250S-1CQ208V 적합 용도: 6 애플리케이션s: Satellite On-Board Data Handling, Payload Telemetry and Command Formatting, Attitude Determination and Control Interface Logic, Spacecraft Bus Communications Bridges, Launch Vehicle Avionics, Instrumentation and Sensor Front-End Processing.
Satellite On-Board Data Handling
The RTAX250S-1CQ208V fits spacecraft on-board computer (OBC) logic where 250,000 gates implement telemetry formatting, memory controllers, and time-tagging around a rad-tolerant processor. Its live-at-power-up behavior means the fabric is functional the instant spacecraft power is applied - no configuration PROM readout delay - which simplifies power-up sequencing and autonomous recovery from brownouts. In this role the 2816-CLB fabric bridges MIL-STD-1553, SpaceWire, and custom bus bridges while the 0.93 ns CLB combinatorial delay supports moderate-speed datapath functions. Because the CQ208 ceramic package is hermetic, the device withstands the vacuum and thermal cycling of low Earth orbit; designers should budget SEU mitigation (TMR, scrubbing) in the fabric per the RTAX-S datasheet reliability guidance.
추천
Payload Telemetry and Command Formatting
Payload data-handling chains use the RTAX250S-1CQ208V to implement CCSDS-class frame formation, compression pre-processing, and downlink formatting at the 4224-logic-cell scale. The part's CMOS process keeps static power low - a critical budget line for payload electronics that are only powered during contact windows - while speed grade -1 timing (0.93 ns/CLB) is ample for telemetry rates well below the fabric's upper bound. The CQ208 footprint leaves generous user I/O for parallel payload interfaces. Prototyping occurs on commercial Axcelerator parts per app note AC170 before flight-programming, letting teams validate the formatter RTL early. When mission radiation analysis shows aggressive environments, the RTAX250SL-1CQ208V drop-in preserves the same footprint with enhanced tolerance.
추천
Attitude Determination and Control Interface Logic
ADCS units employ the RTAX250S-1CQ208V as glue logic between star trackers, sun sensors, reaction-wheel drivers, and the main flight computer. The FPGA aggregates encoder interfaces, generates PWM commands, and performs watchdog functions; the 2816-CLB organization provides enough capacity for redundant-sensor voting logic, a common architectural requirement in ADCS designs. Live-at-power-up operation ensures safe-mode wheel-command paths exist immediately at reset without configuration sequencing. Its true single-chip form factor removes external configuration components from the ADCS reliability chain, improving unit-level parts count and failure-mode budget. The hermetic CQ208 ceramic package supports the conductive-cooling mechanical interfaces typical of attitude-control electronics boxes.
추천
Spacecraft Bus Communications Bridges
Bus avionics such as 1553 remote terminals, CAN gateway logic, and custom inter module links map naturally onto the RTAX250S-1CQ208V. Its 250k-gate capacity implements multiple protocol engines concurrently, and user I/O on the 208-pin ceramic package supports redundant bus interfaces with independent PHY-side connections. Low static power suits always-on bus monitor functions that must remain awake between payloads' duty cycles. Because RTAX-S is a single-chip antifuse-class fabric, bus bridge firmware-in-logic is immutable once programmed - a security and reliability advantage over SRAM FPGAs that can be corrupted in flight. Teams should prototype the bridge RTL on Axcelerator commercial parts (AC170 flow) and lock the flight bitstream only after full integration testing.
추천
Launch Vehicle Avionics
Launch-stage electronics face severe vibration and short mission durations with high reliability demands; the RTAX250S-1CQ208V's hermetic CQ208 ceramic package and live-at-power-up fabric make it a proven choice for stage sequencer support logic, pyrotechnic arm/fire interlock logic, and telemetered health aggregation. The 0.93 ns combinatorial delay at speed grade -1 supports deterministic interlock paths where worst-case timing must be statically provable - an advantage of antifuse-class fabrics over reconfigurable SRAM devices. Programs procuring under defense flows can specify the DLA drawing equivalents (5962-0421901VYC / 5962-0421902QYC), which per the Microchip DLA cross reference are qualified per Mil Prf 38535 and listed on QML class Q/V, simplifying government acceptance.

Instrumentation and Sensor Front-End Processing
Science instruments - imagers, spectrometers, particle detectors - use the RTAX250S-1CQ208V for detector timing generators, co-addition pipelines, and interface FIFOs feeding downstream rad-hard processors. The 4224 logic cells comfortably hold multi-channel acquisition counters, while the FPGA's low CMOS static power preserves the tight thermal budgets of cryogenic-adjacent electronics boxes. Hermetic CQ208 construction prevents outgassing concerns associated with molded commercial packages near optical apertures. Instrument teams commonly share one FPGA design across engineering-model and flight-model units, and the antifuse-class fabric guarantees the flight unit behaves identically to the validated prototype after programming. For deeper pipelines, the RTAX4000S-1CQ352V offers roughly 4M gates in the same family design flow.

설계 노트
RTAX-S devices are programmed once (antifuse-class fabric), so a bitstream error in a ceramic CQ208 flight unit cannot be fixed by reconfiguration - the part is scrap. Complete full RTL freeze, timing closure, and system integration on the commercial Axcelerator prototype per Microchip application note AC170 before programming any flight units. Budget spare flight parts of at least 10-20% of the unit quantity to cover programming yield and handling losses; a single 250k-gate flight FPGA represents significant program cost.
Speed grade selection must be locked before timing sign-off. The '-1' grade gives 0.93 ns combinatorial delay per CLB, while the standard RTAX250S-CQ208V is slower; substituting a standard-speed part into a '-1'-validated footprint without re-running static timing analysis risks marginal paths appearing only at temperature. All drop-in family variants share the CQ208 pinout, but I/O standards and drive strengths should be re-verified in Libero SoC when changing part number suffixes.
Microchip markets RTAX-S on low power consumption and single-chip operation. Because the fabric is live at power-up with no external configuration PROM, total board power and inrush sequencing are simpler than SRAM FPGA designs - but confirm the exact static and dynamic current figures from the RTAX-S/SL datasheet (ds2169) power tables for your activity profile rather than estimating. For SEU resilience, combine the fabric's inherent tolerance with design-level mitigation (triple modular redundancy, watchdogs) sized to your orbit's expected upset rate.
