RTAX2000SL-1CG624PROTO 概述
What is a radiation-tolerant FPGA? An FPGA is an integrated circuit whose logic fabric can be configured after manufacture. A radiation-tolerant FPGA is designed to operate in environments with high-energy particles such as low-Earth orbit, deep space, and avionics. In the product hierarchy, RTAX-S/SL belongs to FPGA -> programmable logic device -> integrated circuit. Unlike ordinary commercial SRAM FPGAs, the RTAX2000SL family is intended for high-reliability systems that require predictable performance under ionizing-radiation exposure and a non-volatile, live-at-power-up architecture.
The RTAX2000SL-1CG624PROTO provides 2,000,000 equivalent system gates, 32,256 logic cells, and 21,504 CLBs in the RTAX2000SL variant. The device is based on advanced CMOS technology and is supplied in the high-density CG624 footprint. According to the Microchip product family page, RTAX-S radiation-tolerant FPGAs combine industry-leading space-flight design advantages including low-power consumption, true single-chip implementation, and live-at-power-up operation.
The architecture is derived from the Microsemi commercial Axcelerator family. Datasheet-level family features include embedded SRAM with built-in FIFO control logic, segmentable clocks, chip-wide highway routing, and carry logic. These resources enable complex digital system implementation without requiring an external boot PROM. The CBGA624 package provides a large number of controlled-impedance interconnects for dense space board designs.
Typical applications include spacecraft command and data handling, launch-vehicle avionics, radiation-tolerant payload processing, secure defense communication baseband processing, and remote-sensing instrument control. The 2M-gate density is large enough for moderate image processing, telemetry formatting, protocol engines, and sensor interfaces, while remaining manageable for single-chip system architectures.
Engineers using this PROTO ordering code should treat it as an engineering/prototype part for system development. When the design matures, select a production screening variant such as RTAX2000SL-1CG624V for flight hardware. Always verify package drawing, thermal management, and I/O assignments from the manufacturer datasheet before committing the layout.

典型应用
RTAX2000SL-1CG624PROTO 适用于 6 应用s: Satellite Command and Data Handling, Launch Vehicle Avionics, Space Payload Signal Processing, Satellite Communication Payload Baseband, Remote Sensing Instrument Control, High-Reliability Avionics Data Router.
Satellite Command and Data Handling
The RTAX2000SL-1CG624PROTO fits satellite command and data handling (C&DH) subsystems where 2,000,000 equivalent gates and 32,256 logic cells are needed for telemetry collection, command decoding, CCSDS framing, and low-level payload control. Its radiation-tolerant RTAX-S/SL architecture and live-at-power-up behavior simplify the single-chip spacecraft computer. The 624-terminal CBGA624 package supports many parallel control and data buses, while low-power operation reduces spacecraft thermal load. In a typical C&DH design, the FPGA monitors bus commands, formats instrument telemetry, and controls power-switching sequences; designers should budget power-supply decoupling and thermal paths from the column-grid package to the board core.
推荐
Launch Vehicle Avionics
For launch vehicle avionics, the RTAX2000SL-1CG624PROTO provides deterministic, radiation-tolerant logic in a ceramic package that is commonly used in flight electronics. Its 2M equivalent gates support sensor conditioning, valve/ordnance fire logic, and redundant telemetry processing. The device is live at power-up, so no external configuration memory is needed to initialize critical safety functions after power-on. In high-vibration launch environments, the column-grid package requires careful solder-joint and mechanical stress analysis. Designers should verify the selected screening flow because PROTO parts are intended for development, while the flight build should use a production-screened CG624 variant such as RTAX2000SL-1CG624V.
推荐
Space Payload Signal Processing
The RTAX2000SL-1CG624PROTO is suited to space payload signal processing when the application requires 32,256 logic cells and 21,504 CLBs in a radiation-tolerant part. It can implement moderate-throughput image pre-processing, packet buffering, DSP datapaths, and sensor data compression. Embedded SRAM with FIFO control logic and segmentable clock resources make payload data-path design more practical than with a simple glue-logic FPGA. Because the CBGA624 package has hundreds of shared I/O and clock pins, engineers can connect multiple high-speed ADC or DAC devices plus a host processor. The design should include adequate power filtering and thermal simulation to remove heat from the ceramic package under worst-case payload workloads.
推荐
Satellite Communication Payload Baseband
The RTAX2000SL-1CG624PROTO is well matched to satellite communication payload baseband processing such as routing, framing, forward-error-correction control, and telemetry management. Its 2,000,000 equivalent system gates allow integration of multiple protocol engines in a single radiation-tolerant FPGA. The RTAX-S/SL family's low-power design is important because communication payload thermal budgets are shared with RF amplifiers and transceivers. The CG624 package offers abundant I/O for connecting to chiplevel ADC/DAC interfaces and backplane data buses. For reliable link operation, verify jitter, temperature range, and I/O standard support from the Microchip datasheet before layout.
推荐
Remote Sensing Instrument Control
In remote sensing instruments, the RTAX2000SL-1CG624PROTO can provide command decoding, timing generation, image-frame formatting, and housekeeping data packaging for optical or radar sensors. With 32,256 logic cells, designers can implement a compact micro-controller-like state machine plus register-based instrument interfaces in one FPGA. The live-at-power-up nature ensures the instrument is responsive immediately after power-on without waiting for configuration loading. The ceramic CBGA624 package gives good thermal stability in orbital thermal cycling conditions. The PROTO ordering code is suitable for sensor breadboards; a production-screened RTAX2000SL CG624 part should be selected for the flight instrument model.
推荐
High-Reliability Avionics Data Router
The RTAX2000SL-1CG624PROTO is suitable for high-reliability avionics data routers and gateways where deterministic operation and radiation tolerance are required. The 2M gates allow multiple serial/parallel bus protocol engines, message buffers, and fault-isolation logic to be integrated on a single CBGA624 FPGA. In addition to space buses such as SpaceWire and MIL-STD-1553 controller glue logic, the FPGA can manage redundant telemetry paths and autonomous reconfiguration sequences. Engineers should carefully define clock domains using the segmentable clock resources to reduce cross-domain timing hazards. Thermal vias under the ceramic package are recommended to keep junction temperature within the datasheet limit.

关键差异点
- PROTO engineering variant enables early flight-FPGA board bring-up without committing to high-reliability production lot （对比 RTAX2000SL-1CG624V)

设计说明
The RTAX2000SL-1CG624PROTO is supplied in a 624-terminal ceramic CBGA624 package. For high-performance space systems, thermal paths rely on the column grid and printed circuit board vias. Use a dense pattern of thermal vias under the package ground pad area and connect them to an internal power/ground plane. Verify the exact thermal resistance values from the manufacturer datasheet revision v18 because they are not repeated in the distributor snippet.
A PROTO ordering code is suitable for development but is not automatically equivalent to a flight-qualified part. Before final design freeze, change to a production-screened CG624 variant such as RTAX2000SL-1CG624V or another approved Microchip flow. Never assume the PROTO part is approved for Class V or Class Y flight use without reviewing the program-approved part list and the Microchip RTAX-S/SL ordering information.
Because the CG624 package has hundreds of ceramic column terminations, the PCB footprint must exactly match the manufacturer-recommended land pattern. Use controlled impedance for differential clock and high-speed serial pins, and keep unused/no-connect pins isolated according to the Microchip package drawing. In high-radiation applications, minimize vias crossing radiation-sensitive analog areas and ensure all power rails are decoupled near the package columns.
