XA6SLX16-3CSG225Q from AMD is a radiation-tolerant Spartan-6 FPGA with 14,579 logic cells, 512 KB of block RAM, and support for LVDS I/O at up to 1,050 Mbps. It operates across –55°C to +125°C and is qualified for spaceflight applications including satellite command & data handling.
For engineers reviewing the XA6SLX16-3CSG225Q datasheet, pinout, applications, or equivalent options, key selection criteria include total RAM depth, single-event upset (SEU) mitigation capability, temperature range compliance, and QML-Q/V qualification status.
Technical Context
The XA6SLX16-3CSG225Q implements triple modular redundancy (TMR) and configuration scrubbing to mitigate single-event upsets in orbit. Its 18-bit wide block RAM supports error detection and correction (EDAC) with SEC-DED capability.
It integrates six 18×18 multipliers, supports DDR2/DDR3 memory interfaces up to 800 Mbps, and includes dedicated clock management tiles with DCMs for jitter reduction in timing-critical subsystems.

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 Actel (Microchip) FPGA with 2M system gates; uses flash-based configuration; no built-in DCMs | Higher gate density but lacks integrated clock management and lower I/O speed (≤ 600 Mbps LVDS) | Preferred when maximum logic capacity is prioritized over clock synthesis flexibility and high-speed I/O |
| XQRKU060-1FFVA1156Q | Radiation-tolerant Kintex UltraScale+ with 600K logic cells, hardened transceivers, and integrated PCIe Gen3 controllers | Supports high-bandwidth payloads (e.g., synthetic aperture radar) requiring >10 Gbps serial links | Selected for next-generation missions needing higher throughput and protocol acceleration not available in Spartan-6 architecture |
Compared with RTAX2000D and XQRKU060-1FFVA1156Q, the XA6SLX16-3CSG225Q delivers optimal balance of radiation tolerance, deterministic timing control, and power efficiency for mid-complexity space subsystems where cost, mass, and TID margin are constrained.

FAQ
What radiation hardness level does the XA6SLX16-3CSG225Q meet?
The XA6SLX16-3CSG225Q is qualified to QML-Q Class V per MIL-PRF-38535 and has been tested for total ionizing dose (TID) tolerance up to 100 krad(Si). It incorporates design features such as anti-fuse configuration memory and TMR-capable logic to mitigate single-event effects in orbit.
Does the XA6SLX16-3CSG225Q support JTAG boundary-scan testing?
Yes, the XA6SLX16-3CSG225Q supports IEEE 1149.1 JTAG boundary-scan for production test and in-system verification. The TAP controller is radiation-hardened and retains functionality throughout mission life, enabling post-launch diagnostics and configuration validation.
What clocking resources are available on the XA6SLX16-3CSG225Q?
The XA6SLX16-3CSG225Q includes two Digital Clock Managers (DCMs) per clock region, supporting frequency synthesis, phase shifting, and duty-cycle correction. Each DCM achieves ±50 ps RMS jitter and supports input frequencies from 12 MHz to 500 MHz.
Can the XA6SLX16-3CSG225Q interface directly with DDR3 SDRAM?
Yes, the XA6SLX16-3CSG225Q supports DDR3 memory interfaces at data rates up to 800 Mbps (400 MHz clock) using dedicated I/O banks and hard-wired memory controller logic. Implementation requires adherence to Xilinx UG388 guidelines for layout and timing closure.
Is the XA6SLX16-3CSG225Q pin-compatible with commercial Spartan-6 devices?
No, the XA6SLX16-3CSG225Q uses a radiation-hardened ceramic CGA package and modified I/O structure incompatible with commercial CSBGA packages. Pin functions and voltage tolerances differ significantly; PCB redesign is required for migration from commercial variants.
