RTAX1000S-1LG624V 개요
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation and single-event effects encountered in orbital and deep-space environments. Unlike reprogrammable SRAM FPGAs, the RTAX-S family uses nonvolatile antifuse technology, in which permanent interconnects are formed at one-time programming. This eliminates configuration-storage vulnerabilities, gives true live-at-power-up operation, and makes the device a single-chip solution in the power management hierarchy of spacecraft avionics systems.
Key features include one-time-programmable antifuse interconnect with no external configuration PROM, up to 540 kbits of embedded SRAM with optional EDAC protection, segmentable clock resources, chip-wide highway routing, and carry logic inherited from the commercial Axcelerator architecture. Total ionizing dose tolerance is 300 krad (functional) and 200 krad (parametric), with SEU rates below 1E-10 errors per bit-day.
The CMOS architecture achieves a maximum combinatorial delay of 0.93 ns on the -1 speed grade. Embedded FIFO control logic and dual-port SRAM blocks support on-board data processing, telemetry formatting, and payload signal chains without external memory in many designs.
Typical applications include satellite payload processing, spacecraft telemetry and command interfaces, radiation-hardened bus controllers, and Earth-observation instrument data acquisition where live-at-power-up behavior is mandated.
Design consideration: because the device is one-time programmable, complete functional simulation and a prototyping pass on the pin-mapped commercial Axcelerator device via Microchip Extender boards or Aldec CG624 adaptor boards are strongly recommended before committing flight parts.

일반적인 애플리케이션
RTAX1000S-1LG624V 적합 용도: 6 애플리케이션s: Satellite Payload Data Processing, Spacecraft Telemetry and Command (TM/TC) Interface, Earth-Observation Instrument Data Acquisition, Radiation-Hardened Bus Controller / Interface Bridge, Launch Vehicle Avionics and Flight Control Logic, Cubesat and SmallSat On-Board Computer Logic.
Satellite Payload Data Processing
The RTAX1000S-1LG624V fits payload processing chains because it combines 18144 logic cells with 540 kbits of embedded SRAM featuring optional EDAC protection, allowing telemetry framing, compression pre-processing, and sensor data formatting entirely on-chip. Its 418 user I/Os interface multiple instrument channels and downlink formatters without glue logic. Used between instrument front-ends and the telemetry encoder, the antifuse fabric delivers deterministic timing (0.93 ns max combinatorial delay) with no configuration-load time. The trade-off versus SRAM FPGAs is one-time programmability, mitigated by the Microchip/Aldec prototyping flow before flight-part programming, while the antifuse bitstream itself is immune to configuration upsets.

Spacecraft Telemetry and Command (TM/TC) Interface
For TM/TC interfaces, the RTAX1000S-1LG624V provides live-at-power-up operation - a mission requirement because command receivers must be functional the instant spacecraft power is applied, with no configuration device boot sequence. The 12096-CLB fabric implements CCSDS framing, decoders, and redundant command majority-voting logic, while sub-1E-10 errors/bit-day SEU rates keep upsets within scrubbing budgets. Its single-chip form factor removes the external configuration PROM that would otherwise be a single point of failure on the critical command path. Designers pair it with rad-hardened power sequencing and verify pinout against the LG624 tables in the RTAX-S/SL datasheet.

Earth-Observation Instrument Data Acquisition
Earth-observation imagers generate high-rate parallel data streams that map efficiently onto the RTAX1000S-1LG624V: the segmentable clock network and chip-wide highway routing distribute high-speed sampling clocks, while carry-logic chains build wide accumulation and correlator datapaths. The 1M-gate density accommodates image deflicker, region-of-interest extraction, and CCSDS packetization. Embedded dual-port SRAM with FIFO control implements line buffers without external memory, reducing board mass and radiation-sensitive part count. Because acquisition logic must not glitch after latchup recovery, the nonvolatile antifuse configuration guarantees instant restoration of the acquisition state machine after power cycling.

Radiation-Hardened Bus Controller / Interface Bridge
Spacecraft backplanes still rely on MIL-STD-1553, SpaceWire, and custom serial bridges, all implementable in the RTAX1000S-1LG624V using its 418 user I/Os and deterministic antifuse fabric. The device bridges legacy protocol cores to modern payload buses, with 0.93 ns combinatorial delay supporting tight protocol turnaround timing. Single-chip operation avoids the configuration-readback security and availability concerns of SRAM FPGAs in trusted-platform designs. For systems migrating between 1553 and SpaceWire, the shared LG624 footprint across the RTAX-S family (RTAX250S/1000S/2000S) lets one PCB layout serve multiple protocol-density variants, cutting qualification cost across product lines.

Launch Vehicle Avionics and Flight Control Logic
Launch environments combine extreme vibration with short, high-reliability missions; the ceramic column grid array (LG624) package of the RTAX1000S-1LG624V provides hermetic column-bonded interconnect suited to these conditions. Flight control sequencing, redundancy management, and safe-and-arm interface logic benefit from live-at-power-up behavior and zero configuration latency - the FPGA is operational before booster ignition power sequencing completes. The 300 krad functional TID tolerance covers the accumulated dose of multi-orbit and suborbital profiles, and the absence of a configuration memory chain removes a launch-delay failure mode. One-time programmability mandates full simulation plus prototyping on commercial Axcelerator parts first.
추천
Cubesat and SmallSat On-Board Computer Logic
SmallSat OBCs value the RTAX1000S-1LG624V for its low static power and true single-chip integration: watchdog, memory scrubbing control, and housekeeping telemetry fit alongside the main application in 18144 logic cells, replacing several discrete glue devices. Antifuse nonvolatility means a brown-out on the small power budget never corrupts configuration - the design resumes correctly at power re-application, which is essential for sun-pointing recovery sequences. EDAC-protected embedded SRAM safeguards critical tables. Designers on constrained budgets use the shared LG624 footprint to start flight builds on RTAX250S and scale to RTAX1000S or RTAX2000S densities without PCB respins as firmware scope grows.

설계 노트
The RTAX1000S-1LG624V is one-time programmable: once antifuses are blown the part cannot be reworked. Never program flight parts before completing gate-level simulation, timing closure, and a hardware prototype. The sanctioned flow targets the equivalent commercial Axcelerator/ProASIC3E device (e.g., via the Aldec ACT-H3Ki-CG624 adaptor or Microchip Extender boards), then transfers the verified design to the RTAX-S antifuse part.
The LG624 ceramic column grid array uses column (fused-ball) interconnect rather than standard solder balls. Specify the correct CCGA reflow profile and inspect columns for coplanarity before assembly; column devices are less tolerant of warped boards than BGA parts. Follow the LG624 land-pattern data in the RTAX-S/SL datasheet and confirm escape routing under the 1.0 mm column pitch with your fabricator.
Estimated: size the core supply for the RTAX1000S static plus dynamic current using the Microchip power calculator with your actual switching activity; antifuse FPGAs have low static power but dynamic current scales with clock count and toggle rates in the 18144-cell fabric. Provide separate core and I/O rails with local decoupling, and verify the exact rail voltages and sequencing against the latest RTAX-S/SL datasheet revision before release.
With up to 418 user I/Os on a 624-ball package, many switching outputs share power returns. Assign banks to balance edge density, use the lowest slew-rate setting that meets timing for non-critical outputs, and place series termination near the driver for point-to-point lines. For single-event transient robustness on long board traces, apply TMR to off-chip handshake signals and use the embedded EDAC on SRAM blocks holding state.
