RTAX2000SL-1CG1152V 概要
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the heavy-ion and proton environments encountered in Earth-orbiting and deep-space missions. Unlike commercial FPGAs, RTAX-S/SL devices combine an anti-fuse, one-time-programmable (OTP) fabric with design-level mitigation (triple-module redundancy implemented via Microchip tools), delivering single-chip solutions that are live at power-up without external configuration memory, which is a decisive advantage for spacecraft avionics, payload controllers, and instrument electronics.
Key features of the RTAX2000SL include embedded SRAM blocks with built-in FIFO control logic, segmentable clock resources, chip-wide highway routing, and dedicated carry logic for arithmetic-intensive datapaths. The SL variant offers reduced power consumption relative to the earlier RTAX2000S, preserving heritage and radiation data continuity recognized by Microchip, ESA documentation, and industry practice.
Architecturally, the device is a digital CMOS fabric based on the commercial Axcelerator accelerator family, re-manufactured on a radiation-tolerant flow. Design entry, synthesis, and timing sign-off are performed with Microchip Libero SoC and Actel/Microsemi legacy toolchains, enabling netlist migration from RTAX-S prototypes and Aldec flash-based adaptor-board prototyping.
Typical applications include satellite payload data processing, spacecraft bus control, telemetry and telecommand interfaces, and radiation-exposed instrument controllers where a true single-chip, live-at-power-up FPGA is mandated.
A critical design consideration is the OTP nature of the fabric: programming is irreversible, so full functional and timing sign-off in Libero plus flight-unit programming procedures are essential; prototype using the Aldec RTAX adaptor or Axcelerator equivalents.

主な用途
RTAX2000SL-1CG1152V の用途: 6 件s: Satellite Payload Data Processing, Spacecraft Bus Control and Avionics, Telemetry and Telecommand Interfaces, Instrumentation and Sensor Electronics for Space Missions, Launch Vehicle and Reentry Systems Electronics, Deep-Space Probe and CubeSat Flight Computers.
Satellite Payload Data Processing
The RTAX2000SL-1CG1152V fits payload data processing because its 2,000,000 equivalent gates, 32,256 logic cells, and 21,504 CLBs provide enough fabric for on-board compression, formatting, and channelization pipelines, while dedicated carry logic accelerates arithmetic datapaths. Embedded SRAM with built-in FIFO control allows buffering between high-rate sensor interfaces and downlink chains without consuming general-purpose logic. In this role the FPGA typically sits between payload sensor front-ends and the telemetry formatter, clocked from segmentable clock resources for multi-domain designs. Because the anti-fuse fabric is live at power-up, the payload initializes deterministically after separation events with no external configuration device to fail in orbit - a quantified reliability benefit over SRAM-based FPGAs in this class.
おすすめ
Spacecraft Bus Control and Avionics
For spacecraft bus control, the RTAX2000SL-1CG1152V provides deterministic, single-chip live-at-power-up logic for power switching sequencing, mode control, and telecommand/telemetry glue logic. The 2,000,000-gate capacity absorbs legacy MIL-STD or custom bus interfaces that would otherwise require multiple discrete devices, while the chip-wide highway routing and segmentable clocks support the mixed slow/fast domains typical of bus electronics. Anti-fuse configuration cannot be corrupted by single-event upsets at the configuration layer, simplifying the mitigation budget relative to SRAM FPGAs that require configuration scrubbing. Program heritage matters here: the RTAX2000S-to-RTAX2000SL equivalence recognized by Microchip and ESA documentation lets programs carry an existing qualification basis forward without requalification.
おすすめ
Telemetry and Telecommand Interfaces
Telemetry and telecommand (TM/TC) chains benefit directly from the RTAX2000SL-1CG1152V's embedded SRAM with FIFO control logic, which implements frame buffering and rate adaptation between the spacecraft clock domain and the RF/ground segment clock domain. The 32,256 logic cells implement encoders, scramblers, and framing state machines with headroom, and carry logic supports CRC and accumulator functions efficiently. Because these interfaces must be available from the instant of power-up during launch and early orbit phase, the anti-fuse live-at-power-up property eliminates boot-time gaps. Designers typically prototype the TM/TC netlist on the Aldec flash-based RTAX adaptor using the EDIF netlist and pinout conversion flow before committing to OTP flight units, preserving full design verification.
おすすめ
Instrumentation and Sensor Electronics for Space Missions
Scientific instruments on orbit require control logic that survives total ionizing dose and single-event effects while delivering deterministic timing to detectors. The RTAX2000SL-1CG1152V provides the -1 speed grade timing margin for detector sequencers and ADC interface controllers, and its 2,000,000 gates absorb calibration logic, histogramming, and event filtering. Segmentable clocks allow precise multi-phase sampling schemes, and embedded SRAM FIFOs decouple detector output rates from processing rates. The hermetic ceramic column grid array package suits the thermal and vacuum environment of space instruments. Using an SL (reduced power) device in these applications lowers dissipation in thermally constrained payloads compared to the RTAX2000S, a measurable system-level advantage cited in Microchip family positioning.
おすすめ
Launch Vehicle and Reentry Systems Electronics
Launch and reentry avionics demand logic that is operational from battery application and immune to configuration memory corruption under heavy vibration and radiation exposure. The RTAX2000SL-1CG1152V meets these needs: anti-fuse OTP programming is permanent and cannot be flipped by single-event upsets, and live-at-power-up operation means sequencing, safe-and-arm interface logic, and health monitoring begin instantly without a configuration load cycle. The 32,256 logic cells and 21,504 CLBs implement redundant voter structures and two-out-of-three schemes, while carry logic supports navigation accumulator computations. The ceramic column grid array provides a hermetic, mechanically robust interconnect for the high-shock environment of launch vehicles and reentry platforms.
おすすめ
Deep-Space Probe and CubeSat Flight Computers
Deep-space probes and higher-class CubeSats use the RTAX2000SL-1CG1152V as the core of flight computers where every milliwatt and every reliability mechanism counts. The SL process variant reduces static power relative to the RTAX2000S, directly benefiting solar- and RTG-power budgets on missions far from the sun. The 2,000,000-gate fabric implements EDAC, watchdog, and recovery state machines alongside the main computation, and the absence of external configuration flash removes a common deep-space failure point. Prototyping with the Aldec RTAX adaptor board on ProASIC3E flash technology lets small teams validate flight software interfaces early. Heritage equivalence with RTAX2000S documented by Microchip and ESA supports mission assurance reviews for these programs.

設計ノート
The RTAX2000SL-1CG1152V is one-time programmable (OTP): anti-fuse programming is irreversible, so programming flight units before full Libero timing sign-off and design review destroys the device. Complete static and dynamic timing closure, verify the EDIF netlist, and prototype on the Aldec flash-based RTAX adaptor (ProASIC3E based) using Microchip's netlist/pinout conversion methodology before committing flight hardware. Budget for engineering-model units in the program plan, since a programming error on a flight part cannot be recovered.
The CG1152 ceramic column grid array requires a land pattern and column pitch verified against the mechanical drawing in the Microchip RTAX-S/SL datasheet (ds2169). If second-sourcing to the lidded LG1152 variant, re-check the land pattern because column and lidded constructions may specify different pad geometry. Use the footprint-compatible adaptor board approach for density migration between CG624 and CG1152 packages, and maintain controlled-impedance stackup documentation for flight qualification reviews.
Estimated: prefer the SL (RTAX2000SL) die over the RTAX2000S when power budget is tight, as Microchip positions the SL variant for reduced static power consumption - a system-level benefit for solar- and RTG-powered spacecraft. Exact static and dynamic current figures for the -1 speed grade at mission temperature must be taken from the power tables in the official RTAX-S/SL datasheet, and worst-case power analysis should use Microchip power tools with flight temperature and radiation conditions.
