This document describes the features and characteristics of Xilinx's programmable PROMs products, including low-power advanced CMOS NOR Flash process, high endurance, and operation over the full industrial temperature range.
The Xilinx Platform Flash series provides in‑system programmable NOR flash devices for FPGA configuration, available in densities from 1 Mb to 32 Mb. The family includes 3.3 V XCFxxS parts (1‑4 Mb) and 1.8 V XCFxxP parts (8‑32 Mb) with serial, parallel, and SelectMAP interfaces.
The devices support IEEE 1149.1/1532 boundary‑scan, JTAG‑based in‑system programming, design revisioning, built‑in data decompression, and optional security features such as read‑protect and write‑protect bits. Electrical characteristics, timing parameters, and TAP specifications are detailed for reliable integration.
