RTAX2000S-1CQ352V 概要
A radiation-tolerant FPGA is a programmable logic device designed to survive the total ionizing dose (TID), single-event latchup (SEL), and single-event upset (SEU) environments of low-Earth-orbit and deep-space missions. Within the power-management-free fabric hierarchy, the RTAX-S family descends from the commercial Axcelerator architecture and occupies the rad-tolerant segment between commercial FPGAs and fully rad-hard ASICs, allowing designers to implement mission logic without the NRE and schedule cost of full-custom silicon.
Key differentiating features include flash-free antifuse-style one-time programmable configuration, live-at-power-up operation that eliminates the external configuration device required by SRAM FPGAs, low static power consumption, and embedded SRAM blocks with built-in FIFO control logic. The RTAX2000S device in the CQ352 hermetic ceramic package supports segmentable clock resources and chip-wide network routing for large space payloads.
Technically, the fabric is based on Axcelerator-class logic modules organized into clusters, with embedded SRAM blocks distributed across the die. The '-1' speed grade defines the timing performance bin, and the 'V' suffix denotes the radiation-tolerant qualification variant per Microchip ordering conventions. Designers implement designs using Synplify/Libero flows and map them onto the RTAX-S macro library.
Typical applications include satellite payload data processing, telemetry and telecommand (TM/TC) controllers, spacecraft bus avionics, and instrument interface bridging on orbital platforms where SEU mitigation and hermetic packaging are mandatory.
A critical design consideration: the device is one-time programmable, so design freeze and extensive qualification (including SEU rate analysis with Microsemi tools) must precede flight-lot programming.

主な用途
RTAX2000S-1CQ352V の用途: 6 件s: Satellite Payload Data Processing, Spacecraft Bus Avionics / TM-TC Controller, Instrument Interface Bridging, Deep-Space Probe Logic, Prototype / Engineering Model Development, Constellation / SmallSat Digital Platforms.
Satellite Payload Data Processing
The RTAX2000S-1CQ352V provides 2,000,000 equivalent gates and 32,256 logic cells, enough capacity for payload DSP chains, frame formatters, and high-speed interface bridges on imaging or communications satellites. Its embedded SRAM blocks with built-in FIFO control logic let designers implement乒乓 buffering and data-path FIFOs without external memory parts, reducing board area and failure modes in orbit. Because the device operates live at power-up from its one-time-programmable fabric, no configuration device is needed, eliminating a common cold-start failure point. The hermetic ceramic CQ352 package withstands launch vibration and vacuum, and the '-1' speed grade timing models in the Libero flow allow deterministic timing closure for payload clock domains.

Spacecraft Bus Avionics / TM-TC Controller
For spacecraft bus control, telemetry and telecommand handling demands deterministic, low-power logic that survives radiation. The RTAX2000S-1CQ352V fits this role with its radiation-tolerant RTAX-S fabric, low static power consumption, and single-chip form factor highlighted by Microchip as key advantages for space-flight systems. The 21,504 CLBs implement bus controllers, CCSDS framing logic, and watchdog/health-monitoring functions, while segmentable clocks support redundant timing domains. Designers typically implement triple-modular redundancy on control state machines; the fabric's SEU behavior is characterized by Microsemi tools to support that analysis. The CQ352 ceramic package provides 352 I/O-capable pins for redundant MIL-STD-1553, UART, and discrete interfaces common in avionics.
おすすめ
Instrument Interface Bridging
Science instruments on orbital platforms generate sensor data that must be bridged to spacecraft data-handling systems with clean timing and low noise. The RTAX2000S-1CQ352V serves as the bridge FPGA, using its 32,256 logic cells to implement protocol conversion between instrument custom links and spacecraft SpaceWire or LVDS backplanes. Embedded SRAM with FIFO control logic absorbs rate mismatch between instrument bursts and downlink streams. Microchip's datasheet emphasizes segmentable clocks and chip-wide routing resources, which help isolate noisy instrument timing from the spacecraft domain. The hermetic CQ352 ceramic package and rad-tolerant 'V' qualification suit instruments in high-radiation orbits such as MEO and polar LEO missions.
おすすめ
Deep-Space Probe Logic
Deep-space missions face severe total ionizing dose and galactic cosmic ray environments where commercial FPGAs fail. The RTAX2000S-1CQ352V, from the RTAX-S radiation-tolerant family, is built on CMOS technology screened for such environments, with the 'V' ordering suffix denoting radiation-tolerant qualification. Its 2M-gate capacity handles autonomy logic, fault-management engines, and communication codecs needed when round-trip communication delays prohibit ground intervention. Live-at-power-up operation guarantees logic availability after safe-mode power cycles without a boot device, a property Microchip explicitly cites for space designers. The CQ352 hermetic ceramic package also tolerates the wide thermal cycling of interplanetary trajectories better than plastic-encapsulated alternatives.
おすすめ
Prototype / Engineering Model Development
Before committing expensive flight lots, space programs validate designs on prototype hardware. The RTAX2000S-1CQ352PROTO variant shares the '-1' speed grade and identical 352-pin CQ352 footprint, so engineering-model boards can be built on the exact flight land pattern while using reduced screening. Aldec's ACT-H3Ki-CQ352 adaptor board, designed for RTAX2000S-class devices, further accelerates validation by providing a footprint-compatible emulation platform with JTAG programming and independent power connectors. Because RTAX-S devices are one-time programmable, teams typically burn design iterations on PROTO units before freezing the flight-lot programming file, making the same-package PROTO pairing an essential part of the RTAX2000S-1CQ352V development flow.
おすすめ
Constellation / SmallSat Digital Platforms
LEO constellations and SmallSats need rad-tolerant logic at moderate cost and schedule. The RTAX2000S-1CQ352V gives a 2M-gate programmable platform in a single hermetic package, replacing multi-chip glue logic and reducing assembly steps. Its low-power CMOS fabric suits power-limited small buses, and the single-chip live-at-power-up configuration removes the configuration flash that adds mass and failure points on compact platforms. Designers can scale within the footprint: the RTAX1000SL-CQ352V and RTAX250SL-CQ352V occupy the same 352-pin CQFP board layout, allowing a common PCBA to be populated with the density each block needs. XAIPART stocks all three densities for quote-based constellation procurement.

設計ノート
RTAX-S devices are one-time programmable: once the flight unit is programmed, the configuration cannot be changed. Freeze the design only after full functional, timing, and SEU-mitigation verification using the Libero/Synplify flow. Burn design iterations on RTAX2000S-1CQ352PROTO or Aldec ACT-H3Ki-CQ352 adaptor hardware before committing the 'V' flight part, and maintain strict configuration-file version control across flight lots.
The CQ352 ceramic CQFP requires careful land-pattern design per the RTAX-S/SL datasheet package section and generous thermal relief because the hermetic ceramic body does not dissipate heat as well as plastic packages. Use symmetric via fan-out under the package to equalize solder-joint stress during thermal cycling, which matters for LEO orbital temperature swings. Because RTAX2000S-class devices offer several package options (CQ352, CG624, LG624, CG1152), designing the board to the family footprint rules enables density migrations without redesign.
Estimated: RTAX-S FPGAs are chosen partly for low static power, but core current still scales with clock activity and resource utilization; budget I/O termination power separately since 352 pins driving LVDS-style loads can dominate total consumption in payload applications. Verify exact core and I/O rail voltages and worst-case current from the official Microchip RTAX-S/SL datasheet power tables and the Microsemi power estimator for your utilization profile before finalizing the power tree.
