RTAX4000SL-1CQ352E 概述
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the heavy-ion and proton environments of space flight, where commercial devices would suffer latch-up, gate rupture, or accumulated single-event effect (SEE) failures. Within the programmable logic hierarchy, the RTAX-SL family sits in the space-grade FPGA tier above commercial-temperature ProASIC/AX lines, using antifuse one-time-programmable technology for live-at-power-up operation and inherently SEU-immune configuration storage.
Key features include 0.15 um CMOS process geometry for a balance of density and radiation hardness, a 1.5V core supply for low power consumption critical to orbital missions, and the ceramic CQFP package providing hermetic sealing and high lead-count I/O suitable for socketed or soldered flight assemblies.
Architecturally, the RTAX4000SL combines Sea-of-Modules logic tiles with embedded SRAM blocks and clock-conditioning resources, letting designers implement high-throughput signal processing, bus interfaces, and telemetry control on a single-chip platform. Because configuration is stored in antifuse elements rather than SRAM cells, the device is immune to configuration upsets, reducing external mitigation overhead.
Typical applications include satellite payload data processing, spacecraft command and data handling, launch-vehicle avionics, and radiation-exposed instrumentation where MIL-STD-883-class screening and extended temperature operation are mandatory.
A key design consideration: antifuse FPGAs are one-time programmable, so design freeze, sign-off simulation, and programming-yield management are part of the flow, and prototype programming must be performed via Microchip (Actel/Microsemi) certified programming hardware.

典型应用
RTAX4000SL-1CQ352E 适用于 6 应用s: Satellite Payload Data Processing, Spacecraft Command and Data Handling, Launch Vehicle Avionics, Radiation-Hardened Instrumentation and Sensing, Prototyping and Pre-Flight Design Verification, Military and Aerospace Embedded Computing.
Satellite Payload Data Processing
The RTAX4000SL-1CQ352E fits payload data processing because its 4,000,000 equivalent gates and 60,480 logic cells provide enough capacity for wide parallel DSP datapaths, FEC coding, and compression engines, while the 1.5V core keeps dynamic power within typical orbital power budgets. In the processing chain it sits between the payload sensor or transceiver interface and the spacecraft formatter, implementing high-throughput pipelines that would overwhelm a smaller RTAX1000SL. Because configuration is stored in antifuse elements, the fabric is live at power-up and immune to configuration upsets, reducing reliance on external watch-dog reconfiguration in orbit. The trade-off is one-time programmability: every payload firmware change requires a new programmed unit, so design freeze and exhaustive simulation are essential before flight-lot programming.
推荐
Spacecraft Command and Data Handling
For command and data handling (CDH), the RTAX4000SL-1CQ352E implements telemetry formatting, MIL-STD-1553 and SpaceWire-class interfaces, memory controllers, and watchdog logic on a single 352-pin CQFP chip. Its -55C to +125C operating range covers launch environments and unheated equipment bays, and the hermetic ceramic package protects the die through vacuum and thermal cycling. The 0.15 um antifuse process offers TID tolerance suited to LEO and MEO missions, and live-at-power-up behavior means the CDH FPGA is functional before any boot sequence, a safety property SRAM FPGAs cannot offer without external configuration storage. Designers should budget pin assignments for redundancy rings and cross-strapping early, since the fixed CQFP pinout limits late IO changes.
推荐
Launch Vehicle Avionics
Launch-vehicle avionics demand logic that is immediately functional at power application and tolerant of high vibration and broad temperature swings; the RTAX4000SL-1CQ352E addresses both with antifuse live-at-power-up configuration and a rugged 352-terminal ceramic CQFP rated -55C to +125C. Typical flight-logic roles include stage sequencing, safe-and-arm interface control, telemetry acquisition, and GPS receiver front-end processing, where the 4M-gate capacity absorbs multiple functional blocks in one screened device, reducing part count and board area. Because flight units are one-time programmable, avionics teams normally program prototype quantities via Microchip-certified programmers and reserve flight lots from the same wafer lot for traceability. Power rails at 1.5V core simplify integration with rad-hard point-of-load converters.
推荐
Radiation-Hardened Instrumentation and Sensing
Science instruments on orbital and deep-space platforms use the RTAX4000SL-1CQ352E to perform on-board data reduction, detector timing, and control-loop processing close to the sensor head. The 0.15 um CMOS antifuse technology provides cumulative-dose tolerance appropriate for multi-year missions, while 60,480 logic cells accommodate parallel ADC front-end processing, histogramming, and packetization. The hermetic CQFP package with 0.500 mm pitch supports the high lead counts instrument boards need for differential analog interfaces without giving up solderability on standard SMD assemblies. Compared with reprogramming SRAM devices, the fixed antifuse configuration simplifies radiation assurance documentation because configuration upsets are excluded by construction - reviewers only need TID and SEL lot data for sign-off.
推荐
Prototyping and Pre-Flight Design Verification
Because RTAX-SL antifuse devices are one-time programmable, design teams prototype in the RTAX-SL ecosystem using programming adapters such as the Aldec ACT-H3Ki-CQ352, which provides power and JTAG programming compatibility with the CQ352 footprint, before committing flight units like RTAX4000SL-1CQ352E. The 4M-gate part lets the full gate-level netlist be exercised in the target package, catching pin-assignment, timing, and power-distribution errors that small prototypes miss. Microchip's Libero SoC flow supports timing sign-off at the -1 speed grade and I 0.5V supply corners. A disciplined flow programs multiple prototype units per iteration, since each programming is permanent and programming-yield is a budgeted variable in the development schedule.
推荐
Military and Aerospace Embedded Computing
Beyond pure space flight, defense embedded computing boards - radar signal processors, secure communications, and bus controllers - use RTAX4000SL-1CQ352E where the extended -55C to +125C range, hermetic CQFP package, and QML-style screening heritage fit program requirements. The 4,000,000-gate capacity implements fabric-level signal processing and cryptographic offload alongside interface bridging, while the single-chip antifuse form factor removes configuration FLASH from the bill of materials, a security benefit since no bitstream exists to intercept or corrupt. The 1.5V core integrates with standard military power architectures through rad-tolerant or hi-rel DC-DC converters. Boards designed around the CQ352 footprint can be re-scaled across RTAX-SL densities, protecting investment as processing requirements grow.

设计说明
The RTAX4000SL-1CQ352E requires a 1.5V core supply with monotonic ramp behavior; because antifuse FPGAs are live at power-up, core integrity during the first milliseconds determines reliable initialization. Generate rails with rad-tolerant point-of-load converters, place bulk capacitance plus 0.1 uF ceramic decoupling at each power/ground pin pair of the CQFP, and follow the DS2169 datasheet power-supply table for I/O bank and auxiliary rails. Sequence I/O after core where the board design allows.
This is a one-time-programmable antifuse device - there is no rework path. Complete timing sign-off at the -1 speed grade across temperature in Libero SoC, run gate-level simulation of the final netlist, and confirm pin assignments against the CQ352 pinout file before submitting to programming. Budget for programming yield by ordering spare units per lot, and reserve flight units from the same wafer lot as prototypes for traceability in radiation assurance documentation.
The 0.500 mm terminal pitch of the 352-pin CQFP allows standard SMD assembly but demands careful pad geometry: use the package land-pattern file from Microchip, keep fan-out symmetric to avoid solder-wicking skew, and define the footprint so all RTAX-SL CQ352 densities (RTAX250SL through RTAX4000SL) can be substituted without re-layout. Provide generous ground vias adjacent to ground leads and isolate sensitive clock leads from switching I/O to preserve signal integrity in vacuum thermal cycling.
