RTAX2000SL-1LG1152V 개요
A radiation-tolerant FPGA is a programmable logic device qualified to survive the total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SET/SEU) environment of spaceflight, sitting within the hierarchy: FPGA -> programmable logic device -> digital IC -> space-grade semiconductor. Unlike SRAM-based FPGAs, the RTAX-S/SL family uses antifuse programmable interconnect, which is one-time programmable and therefore configuration-data immune to SEU effects, enabling live-at-power-up operation without an external configuration flash.
Key features include true single-chip form factor (no boot PROM required), low static power consumption critical for power-constrained spacecraft, and the SL process refinement of the RTAX-S architecture. According to the Microchip RTAX-S/SL datasheet, the family is the FPGA of choice for space designers requiring high logic capacity with radiation performance validated for flight programs.
Architecturally, the device combines the Actel/Microsemi Axcelerator-derived logic fabric with radiation-hardened interconnect, supporting synchronous and asynchronous designs implemented through Microchip/Libero design flow. The 1152-pin CGA package provides the I/O count needed for payloads, buses, and telemetry interfaces in high-density avionics.
Typical applications include satellite payload data processing, spacecraft avionics and attitude-control logic, telecommand/telemetry interfaces, and radiation-hardened glue logic replacing multiple ASICs or MIL-STD parts. The RTAX2000SL-1LG1152V fits missions where high gate count, configuration SEU immunity, and deterministic power-up behavior outweigh reprogrammability.
Design consideration: because antifuse FPGAs are one-time programmable, full design verification and the vendor's prototyping methodology (RTAX2000SL-1LG1152PROTO plus adaptor boards and EDIF netlist conversion) must be completed before programming flight devices.

일반적인 애플리케이션
RTAX2000SL-1LG1152V 적합 용도: 6 애플리케이션s: Satellite Payload Data Processing, Spacecraft Avionics and Command Logic, Telecommand and Telemetry Interfaces, Instrument Control and Data Acquisition, Launch Vehicle and Reentry Avionics, Radiation-Hardened Glue Logic and ASIC Emulation.
Satellite Payload Data Processing
High-capacity on-board processing of sensor and instrument data streams. The RTAX2000SL-1LG1152V provides 2,000,000 equivalent gates and 32,256 logic cells, sufficient for DSP datapaths, framing engines, and lossless-compression pipelines inside payload electronics. Its antifuse fabric is configuration-immune to single-event upsets, eliminating the scrubbing controller and boot PROM that SRAM-based payload FPGAs require, so the design is live at power-up with deterministic startup timing. The 1152-pin CGA supplies the high user-I/O count needed to interface multiple instrument channels, LVDS links, and memory banks simultaneously. In payload implementations, designers typically place the FPGA between instrument front ends and downlink formatters, using the -1 speed grade for pipeline timing closure. The trade-off versus reprogrammable alternatives is one-time programming, so all payload logic must be fully verified before flight-unit programming.

Spacecraft Avionics and Command Logic
Central avionics glue logic, bus bridges, and state machines for spacecraft control electronics. The RTAX2000SL-1LG1152V's single-chip, live-at-power-up behavior simplifies power sequencing and FDIR (fault detection, isolation, recovery) analysis, since no configuration memory can be corrupted by radiation. With 21,504 CLBs, it consolidates functions that would otherwise require multiple rad-hard ASICs or MIL-STD logic devices, reducing board area, mass, and assembly count in flight avionics. The 1152-pin package provides abundant I/O for MIL-STD-1553-style interfaces, discrete telemetry lines, and SPI/UART links to instrument microcontrollers. Low static power consumption matters in avionics where heater and bus power budgets are tightly allocated. Design flow is Libero SoC with the RTAX timing models, and flight designs must be locked before antifuse programming since the fabric is one-time programmable.
추천
Telecommand and Telemetry Interfaces
Implementation of TC/TM encoding, decoding, and framing per spacecraft communication protocols. The RTAX2000SL-1LG1152V suits this role because its antifuse configuration cannot experience configuration-memory upsets, a critical property for the command chain where a corrupted bitstream could disable the entire spacecraft. The 32,256 logic cells accommodate convolutional encoders, CRC blocks, packet routers, and time-tagging logic concurrently, while the high pin count of the CG1152 package supports redundant serial interfaces and hot/cold unit cross-strapping. The -1 speed grade comfortably meets typical TM frame-rate timing requirements with margin. In telemetry implementations the FPGA bridges instrument raw data to the on-board computer, adding monotonicity checks and Housekeeping parameter packing. Live-at-power-up operation ensures telemetry is available immediately after power switch events without waiting for configuration load.
추천
Instrument Control and Data Acquisition
Sequencing, digitizer interfacing, and real-time control for scientific instruments on research and observation satellites. The RTAX2000SL-1LG1152V provides 2,000,000 gates for histogramming engines, detector timing generators, and high-speed FIFO structures, with the 1152-pin CGA delivering the parallel I/O required to capture multi-channel ADC data simultaneously. Its radiation-tolerant antifuse fabric maintains functional integrity under total ionizing dose and single-event conditions specified for the RTAX-S family, which is essential for instruments operating through polar orbits or within belt crossings. Low-power operation supports thermally constrained optical benches where dissipation is limited. Designers implement acquisition pipelines with deterministic latency, exploiting the CMOS logic fabric timing models in Libero. Because the device is one-time programmable, instrument firmware changes require the prototyping-plus-EDIF-conversion methodology Microchip publishes before flight units are programmed.
추천
Launch Vehicle and Reentry Avionics
Flight-critical sequencing, separation-event logic, and health monitoring in launch and reentry vehicles. The RTAX2000SL-1LG1152V's instant-on, single-chip operation guarantees logic availability from the first moment of battery activation, with no configuration load time during the brief powered timeline of a flight. Its antifuse interconnect is immune to configuration upsets induced by the harsh radiation environment of high-altitude trajectories, and the flight-grade V screening supports mission assurance requirements. The 2,000,000-gate capacity integrates red-channel/blue-channel redundant control lanes plus voting logic on one die, and the 1152-pin package fans out to pyro-driver discretes, IMU interfaces, and cross-strapped redundant channels. Low static power suits battery-limited flight timelines. These mission profiles typically dual-source nothing: full lot traceability and certificates of conformance are mandatory for every programmed unit.

Radiation-Hardened Glue Logic and ASIC Emulation
Replacement of obsolete rad-hard SSI/MSI logic and ASIC prototyping in legacy spacecraft electronics. The RTAX2000SL-1LG1152V consolidates dozens of address decoders, bus transceivers, sequencers, and interface adapters into one 2,000,000-gate device, cutting component count, board space, and the associated screening burden of discrete rad-hard parts. The 1152-pin CGA provides the extensive I/O needed to emulate wide legacy ASIC buses (address, data, and control) simultaneously during system bring-up. Because the antifuse fabric is configured once, qualified netlists behave identically in every flight unit, supporting deterministic qualification campaigns. Microchip's documented prototyping path uses the RTAX2000SL-1LG1152PROTO with footprint-compatible adaptor boards and EDIF netlist conversion to validate designs before committing flight devices. Compared with full rad-hard ASIC development, this approach removes NRE mask costs and yields repeatable, off-the-shelf silicon for programs of one to a few satellites.

설계 노트
Antifuse FPGAs are one-time programmable: a single programming error destroys the flight device. Follow Microchip's documented prototyping methodology - implement on RTAX2000SL-1LG1152PROTO (same 1152-pin footprint) using footprint-compatible adaptor boards with EDIF netlist and pinout conversion (see application note Prototyping for RTAX-S and RTAX-SL Devices). Freeze and fully verify the netlist, run static timing with -1 speed grade models, and complete all reviews before programming any -V flight unit.
The CG1152 ceramic column grid array requires careful land-pattern and column-repair-friendly layout per the datasheet package section. Plan board stackup for controlled impedance on all high-speed I/O banks, and provide adequate via fanout for the 1152 columns without exceeding assemble-and-inspect capability. Because radiation-tolerant designs frequently use triple-module redundancy, reserve spare board routing and I/O for TMR-replicated signals rather than packing utilization to the architectural maximum.
One key advantage of the RTAX2000SL is live-at-power-up, single-chip operation with no configuration PROM current or load-time surge. Still, budget static and dynamic core power from Microchip's RTAX-S/SL power estimation tools using your actual netlist toggle rates, since the 2,000,000-gate fabric dissipation is design-dependent. Avoid [DATA_NEEDED]-style guessing: generate power estimates inside Libero with the -1 speed grade models for your finalized design before sizing the spacecraft power bus.
