مقدمة المنتج:XCF04SVOG20C مقدمة المنتج

The XCF04SVOG20C is a member of the Xilinx Platform Flash PROM family, providing 4Mbit of in-system programmable non-volatile storage for Xilinx FPGA configuration bitstreams. Built on a low-power CMOS NOR Flash process, it supports Master Serial and Slave Serial configuration modes at clock rates up to 33MHz, with direct connection to the FPGA configuration pins (CCLK, DIN, PROGRAM_B, INIT_B, DONE). Programming is performed via the JTAG interface (IEEE 1149.1) using Xilinx iMPACT or Vivado tools. The dedicated VCCJ supply allows JTAG I/O compatibility with voltage levels from 2.5V to 3.3V, while VCCO supports 1.8V to 3.3V for configuration interface compatibility with different FPGA voltage standards.

مبدأ العمل:XCF04SVOG20C مبدأ العمل

The XCF04SVOG20C operates through two primary modes. (1) In configuration mode, upon FPGA power-up, the FPGA asserts PROGRAM_B to clear its configuration memory, then releases it and signals readiness via INIT_B. The PROM detects the configuration start, asserts its internal address counter, and begins clocking data out on the D0 pin synchronized to CCLK from the FPGA. In Master Serial mode, the FPGA generates CCLK; in Slave Serial mode, an external clock drives both devices. (2) In JTAG programming mode, the TAP (Test Access Port) controller processes TCK, TMS, TDI, and TDO signals according to IEEE 1149.1, loading the Flash memory array with the FPGA bitstream. The JTAG interface also supports daisy-chaining multiple PROMs for larger bitstream storage and verification readback.
