RTAX1000SL-1CQ352V 概述
A radiation-tolerant FPGA is a field-programmable gate array qualified to survive the total ionizing dose (TID) and single-event effect (SEE) environments encountered in space flight. Within the power-management hierarchy of spacecraft avionics, the RTAX-S/SL family sits at the top of Microchip's rad-hard logic portfolio: FPGA -> radiation-tolerant programmable logic -> space-grade IC. Unlike flash- or SRAM-based FPGAs, the RTAX-S/SL family uses antifuse programmable interconnect that is one-time programmed, providing live-at-power-up operation with no external configuration storage required.
Key features include 1,000,000 system gates of capacity, embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic chains. Because the configuration is locked into the antifuse fabric, the device is immune to configuration upsets that plague SRAM FPGAs, dramatically reducing SEU-driven system-level mitigation overhead.
The RTAX1000SL is based on the commercial Axcelerator architecture, so designers can prototype on cost-effective Axcelerator devices and migrate using Microchip's footprint-compatible adaptor board methodology and EDIF netlist/pinout conversion flow described in the RTAX-S/SL datasheet.
Typical applications include spacecraft avionics buses, satellite payload data processing, telemetry/command interfaces, and instrument control in low-Earth-orbit and deep-space missions where low power and single-chip form factor matter.
A key design consideration: antifuse devices are one-time programmable, so functional verification (simulation and hardware prototyping on Axcelerator equivalents) must be completed before programming flight units.

典型应用
RTAX1000SL-1CQ352V 适用于 6 应用s: Spacecraft Avionics and Onboard Computing, Satellite Payload Data Processing, Telemetry, Tracking and Command (TT&C) Interfaces, Scientific Instrument Control and Data Acquisition, Launch Vehicle Electronics, Deep-Space Probe Digital Subsystems.
Spacecraft Avionics and Onboard Computing
The RTAX1000SL-1CQ352V fits spacecraft avionics controllers because its antifuse fabric cannot experience configuration upsets, eliminating the external configuration-memory failure mode and the associated SEU-mitigation overhead that SRAM FPGAs require in orbit. Its 1,000,000 system gates (12,096 CLBs) comfortably implement MIL-STD-class bus interfaces, housekeeping telemetry, and watchdog logic, while the CQ352 ceramic package provides the hermeticity and thermal path expected in flight hardware. In a typical avionics stack the device sits between a rad-hardened microcontroller and sensor/power subsystems, using its segmentable clocks to time-gate power-hungry domains. Because it is live at power-up, critical safe-mode logic is active from the first millisecond after power switch-on, a hard requirement for launch vehicles and recovery modes.
推荐
Satellite Payload Data Processing
Payload signal chains benefit from the RTAX1000SL-1CQ352V's embedded SRAM blocks with built-in FIFO control logic, which buffer high-rate instrument data between ADC front ends and downlink formatters without external FIFO chips. The 1,000,000-gate capacity (18,144 logic cells) accommodates framing, scrambling, forward-error-correction blocks, and packet routers for typical medium-rate payloads. Carry logic accelerates the arithmetic datapaths common in digital downconversion and filtering. Because the part draws low static power on its CMOS antifuse process compared to SRAM FPGAs of similar density, payload duty-cycled operation directly extends battery energy budgets on small satellites. The chip-wide highway routing keeps wide datapaths timing-clean at payload clock rates, and one-time programming guarantees the flight configuration bitstream is identical on every spacecraft produced.
推荐
Telemetry, Tracking and Command (TT&C) Interfaces
TT&C subsystems demand immediate availability of command decoding after power application - exactly what the RTAX1000SL-1CQ352V delivers with its live-at-power-up antifuse configuration. The device implements redundant command decoders, majority-voted mode control, and telemetry formatting within its 12,096 CLBs, while chip-wide highway routing distributes global enables and reset signals across the die without excessive skew. Its single-chip form factor removes the external PROM or flash that would otherwise need radiation qualification, simplifying parts-stress analysis for TT&C boards. Designers typically place it downstream of the receiver baseband and upstream of the spacecraft controller, using the segmentable clock network to separate the uplink clock domain from the spacecraft time reference, preserving clean CDC boundaries in safety-critical command paths.
推荐
Scientific Instrument Control and Data Acquisition
Science instruments on LEO and deep-space missions use the RTAX1000SL-1CQ352V to sequence detectors, timestamp events, and compress data before downlink. The 18,144 logic cells support multi-channel acquisition controllers, while embedded SRAM FIFOs decouple bursty detector output from steady downlink rates. The CMOS antifuse process exhibits low power draw, which matters for instruments constrained by limited radiator area and thermal budget on the CQ352 ceramic package. Because the configuration is permanent, calibration constants and acquisition sequences programmed into flight units remain fixed through vibration, thermal cycling, and years in orbit - a repeatability property instrumentation programs value for data provenance. The Axcelerator-based prototyping flow lets instrument teams validate acquisition firmware on commercial silicon before committing scarce flight devices to programming.
推荐
Launch Vehicle Electronics
Launch vehicle avionics require deterministic, instantly-available control logic through the seconds-long powered flight phase, and the RTAX1000SL-1CQ352V meets this with zero configuration latency from its antifuse fabric. Flight computers use its dedicated carry logic for guidance arithmetic and its 1,000,000-gate capacity for redundancy management, voting across triple-string sensor inputs. The CQ352 ceramic package withstands the vibration and thermal profiles of launch environments, and the -V flight screening aligns with typical vehicle-range part requirements. Segmentable clocks allow the sequencer, flight-processor interface, and telemetry blocks to run on independent timing domains. Since a single-chip solution eliminates configuration read operations, there is no window during boost where the FPGA is partially configured - a subtle but real reliability advantage for ignition-critical control paths.
推荐
Deep-Space Probe Digital Subsystems
Deep-space missions face total ionizing dose and single-event environments far harsher than LEO, and the RTAX1000SL-1CQ352V's radiation-tolerant antifuse architecture is engineered for exactly this regime. Its immune configuration fabric means the probe's sequencing state machines never lose their bitstream under heavy ion flux, while the low-power CMOS process conserves the scarce electrical power available from RTG or distant-sun solar arrays. The 12,096 CLBs implement fault-tolerant uplink decoders, autonomous safe-mode controllers, and instrument multiplexers typical of probe digital subsystems. The hermetic CQ352 ceramic package supports the long-duration thermal cycling of multi-year cruise phases. Teams prototype on Axcelerator devices using Microchip's documented adaptor-board and netlist-conversion methodology, then program flight units late in AIT to lock in the final validated configuration.

设计说明
Antifuse FPGAs are one-time programmable: a mis-programmed RTAX1000SL-1CQ352V flight unit cannot be reworked and must be scrapped. Complete full RTL simulation, timing closure, and hardware prototyping on a commercial Axcelerator device (e.g., A3PE3000) before programming flight units. Microchip documents this prototyping methodology - footprint-compatible adaptor board plus EDIF netlist and pinout conversion - in the RTAX-S/SL datasheet and the application note 'Prototyping for RTAX-S and RTAX-SL Devices.' Budget at least one spare programmed unit per flight lot for anomaly investigation.
The CQ352 ceramic quad flat pack is a hermetic, high-lead-count package intended for flight boards. Follow the RTAX-S/SL datasheet land-pattern and thermal-pad guidance, and verify PC card warp requirements since ceramic packages tolerate less board flexure than plastic QFPs. Use Microchip's documented footprint-compatible adaptor board methodology when prototyping so the same PCB layout serves both Axcelerator prototype devices and RTAX-S flight devices, eliminating layout-driven migration risk between prototype and flight builds.
Verify core and I/O supply sequencing and current limits against the RTAX-S/SL datasheet electrical tables before power-supply design freeze. RTAX-S devices are live at power-up because the antifuse fabric needs no configuration load, so supply ramp behavior directly affects the first functional moments of the board. Confirm the operating current figures for your specific density (1M-gate class) and toggle rate from the manufacturer datasheet rather than scaling from other densities - power tables are per-device in the Microchip documentation.
Screening suffixes matter in space programs: RTAX1000SL-1CQ352V (V suffix) and RTAX1000SL-1CQ352E (E suffix) share the same die and package but correspond to different qualification flows, some of which are covered by DLA standard microcircuit drawings (e.g., 5962-0422006VXC for the -1CQ352V). Substituting the wrong suffix can fail program parts-approval review even though electrically the parts are equivalent. Always confirm the required screening level and DLA drawing number with your program office before ordering or substituting.
