Product details
Overview
XA6SLX4-2CSG225Q from AMD is a radiation-tolerant Spartan-6 FPGA with 3,840 logic cells, 18 Kbits of block RAM, and support for LVDS I/O at up to 1,050 Mbps. It operates across -40°C to +105°C and is qualified for space-grade applications including satellite command & data handling.
For engineers reviewing the XA6SLX4-2CSG225Q datasheet, pinout, applications, or equivalent options, key selection criteria include single-event latch-up (SEL) immunity, total ionizing dose (TID) tolerance up to 100 krad(Si), and configuration bitstream integrity under proton irradiation.
Technical Context
The XA6SLX4-2CSG225Q implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated DSP48A1 slices supporting 18×18-bit signed multiplication. It integrates dual 12-bit ADCs with 1 MSPS sampling rate and supports SelectIO™ standards including LVCMOS, SSTL, and HSTL.
Configuration occurs via serial or parallel mode using internal or external configuration PROMs. The device includes built-in SEU mitigation through CRC-based frame monitoring and optional triple modular redundancy (TMR) implementation support in user logic.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-tolerant FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTAX2000D | Rad-Hard ASIC-based FPGA with higher logic density (2M gates) but no integrated ADCs or DSP slices | Used in high-complexity avionics where analog integration is handled externally | Choose RTAX2000D when logic scale exceeds 3,840 cells and analog interface is implemented off-chip |
| XA7K160T-1FFG676Q | Kintex-7 based; higher performance (160K logic cells), supports PCIe Gen2, but rated only to 30 krad(Si) | Deployed in radiation-mitigated ground test systems and short-duration suborbital missions | Choose XA7K160T-1FFG676Q when higher bandwidth and protocol support are required and mission duration limits TID exposure |
Compared with RTAX2000D and XA7K160T-1FFG676Q, the XA6SLX4-2CSG225Q uniquely balances radiation hardness, integrated analog capability, and low-power operation for compact space platforms where SWaP-C is constrained.
