For engineers reviewing the XA7A25T-2CSG325I datasheet, pinout, applications, or equivalent options, key selection factors include single-event upset (SEU) mitigation architecture, TID rating of 100 krad(Si), and QML-V qualification per MIL-PRF-38535 Class V.
Technical Context
This FPGA implements triple modular redundancy (TMR) in configuration memory and supports scrubbing via dedicated ICAP interface. It integrates 12 GTX transceivers with built-in PRBS generators and error detectors for high-integrity serial links.
The device uses 28 nm HPL process technology and includes hardened PCIe Gen2 endpoint logic, AXI-4 interconnect fabric, and clock management tiles with MMCM/PLL support for deterministic timing closure in radiation environments.
