Typical Applications
RTAX2000SL-1CQ352V is suitable for 6 applications: Satellite Payload Data Processing, Spacecraft Bus Control and Housekeeping Logic, Launch Vehicle Avionics, Deep-Space Instrument Data Acquisition, Satellite Telecommand and Telemetry Interfaces, Reprogrammable Prototyping of Space Designs.
Satellite Payload Data Processing
The RTAX2000SL-1CQ352V provides 2,000,000 gates of flight-qualified logic for payload formatting, compression preprocessing, and high-rate data-path interfacing in LEO, GEO, and deep-space missions. Its antifuse OTP fabric delivers deterministic live-at-power-up behavior - critical for payload power-on sequencing - while the SL fabric's SEU mitigation reduces reliance on external triple-module redundancy. Embedded SRAM blocks with built-in FIFO control buffer telemetry streams without external memory parts, cutting board area and mass. At 1.5V nominal core operation, static power stays low during eclipse-mode load-shedding. Place the device between sensor front-ends and the downlink chain, and budget 30-40% gate margin for on-orbit algorithm updates via ground-commanded mode selection, since the fabric itself is one-time programmable.
Recommended
Spacecraft Bus Control and Housekeeping Logic
Spacecraft bus controllers require dependable glue logic for OBC interfaces, telemetry/command (TM/TC) formatting, and power-distribution monitoring. The RTAX2000SL-1CQ352V fits this role because it is a true single-chip solution: no external configuration PROM or scrubbing controller is needed, improving reliability of the boot path. Its 21,504 CLBs absorb MIL-STD-1553, SpaceWire, and UART-style interface logic comfortably, and segmentable clock resources isolate timing domains between the processor subsystem and housekeeping logic. According to Microchip, low-power consumption and live-at-power-up operation make RTAX-S the FPGA of choice for space bus designers. Deploy it on the 1.5V regulated avionics rail with radiation-characterized decoupling per the RTAX-S/SL datasheet power guidelines.
Recommended
Launch Vehicle Avionics
Launch avionics demand logic that is guaranteed functional at power-up with zero configuration delay, since flight timelines from ignition to orbit leave no window for bitstream loading. The RTAX2000SL-1CQ352V meets this requirement through antifuse OTP configuration and is vibration-tolerant thanks to its ceramic CQFP package suited to high-shock environments. Its 2,000,000-gate capacity implements redundant flight-computer voting logic, safe-and-arm interface control, and IMU data fusion paths within a single device, reducing part count in the critical string. The 1.425V to 1.575V core window integrates with standard 1.5V rad-tolerant point-of-load regulators. Prototype on the RTAX2000SL-1CQ352PROTO before committing flight OTP units to avoid rework in qualified hardware.
Recommended
Deep-Space Instrument Data Acquisition
Science instruments on planetary probes face extreme TID and heavy-ion fluence, where configuration upsets would end a mission. The RTAX2000SL-1CQ352V's antifuse configuration is inherently immune to such upset, and the SL fabric adds SEU tolerance in the logic path, matching Multi-Mission Radioisotope Thermoelectric Generator-class mission profiles. Its embedded SRAM/FIFO blocks stage ADC data from spectrometers and imagers, while chip-wide highway routing distributes sampling clocks with low skew across the 32,256-cell fabric. Low static power at 1.5V suits power-constrained RTG platforms. Design the acquisition chain so all control state machines avoid RAM-based storage, exploiting OTP determinism; verify heavy-ion behavior per the RTAX-S/SL radiation report referenced in the Microchip datasheet.
Recommended
Satellite Telecommand and Telemetry Interfaces
TM/TC front-ends continuously decode uplink commands and format downlink frames, so they must survive years of single-event particles without configuration loss. The RTAX2000SL-1CQ352V implements CCSDS frame processing, convolutional encoding hooks, and redundant command-decoder voting in its 2,000,000-gate fabric, with the SL SEU-mitigated flip-flops protecting decoder state. Because the device powers up live, the receiver chain is available immediately after bus power application, shortening LEOP safe-mode timelines. Interface it to the OBC over UART/LVDS-style I/O banks, and keep the 1.5V core on a filtered rail with the datasheet-recommended decoupling to minimize switching noise coupling into sensitive RF receivers colocated on the avionics board.
Recommended
Reprogrammable Prototyping of Space Designs
Because RTAX-S/SL devices are one-time programmable, every flight design must be prototyped before programming hardware. Microchip and Aldec jointly offer a prototyping solution that maps RTAX designs onto flash-based ProASIC3E FPGAs, but the simplest board-level path is the pin-compatible RTAX2000SL-1CQ352PROTO device, which occupies the same 352-pin CQFP footprint and supports repeated programming on flight-representative hardware. The RTAX2000SL-1CQ352V target uses 2,000,000 gates (21,504 CLBs), so timing and utilization correlation from prototype to flight device should be validated in Libero SoC timing reports. Maintain the prototype socket on the engineering model PCB so the flight unit can be inserted without layout change once qualification testing completes.

- Same-footprint capacity upgrade path (vs RTAX4000SL-CQ352EV)

Design Notes
Regulate the 1.5V core within the 1.425V to 1.575V window under all load and temperature corners; antifuse FPGA static and dynamic timing guarantees in the RTAX-S/SL datasheet assume this window. Estimated: with a nominal 1.5V rail, even 75 mV of IR drop across power-plane copper at multi-amp transient loads can consume half the tolerance band, so use remote sensing at the CQ352 power pins and radiation-tolerant point-of-load regulators with soft-start to avoid inrush during spacecraft bus power-up sequencing.
RTAX-S/SL devices are one-time programmable: a programming error on a flight RTAX2000SL-1CQ352V scrapes the unit. Always complete functional, timing, and environmental validation on the pin-compatible RTAX2000SL-1CQ352PROTO device or the Aldec ProASIC3E-based prototyping adaptor before programming flight hardware. Also confirm the Libero SoC programming file targets the exact device density and speed grade; a 4M-target file will not program a 2M device and vice versa. Order flight units with lot traceability and DLA documentation if your program requires Mil-Prf-38535 flow evidence.
The 352-pin ceramic CQFP requires careful solder-joint reliability engineering: use the datasheet land pattern, support corner pins with additional fillet per IPC-class space workmanship, and account for CTE mismatch between the ceramic package and the flight PCB laminate when selecting stackup. Place 0.1 uF decoupling capacitors at each core power pin pair plus bulk capacitance near the board entry; keep the shortest possible return path for high-speed I/O banks by stitching ground vias adjacent to signal escapes. Follow the RTAX-S/SL datasheet board layout guidelines for programming and JTAG routing.
Compliance Information
Space-grade ceramic-packaged device; hermetic ceramic CQFP packaging is typical for this class. Specific RoHS/REACH declarations were not present in the provided data - request compliance certificates from Microchip or distributor. Qualified per Microchip DLA cross-reference documentation associated with Mil-Prf-38535 QML flows for flight programs; verify SMD drawing number applicability for this exact MPN.
