Product details
Overview
XC5VLX85-1FFG676I from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 85,200 logic cells, 4.25 Mb of block RAM, and 240 DSP48E slices. It supports PCIe Gen1 x8, RocketIO GTP transceivers up to 3.75 Gbps, and operates at -1 speed grade with industrial temperature range (-40°C to +100°C). It is used in high-performance digital signal processing and reconfigurable computing systems.
For engineers reviewing the XC5VLX85-1FFG676I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (448 user I/Os), transceiver capability (GTP), thermal rating (industrial), and configuration interface (SelectMAP, JTAG, SPI).
Technical Context
The XC5VLX85-1FFG676I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, and dedicated routing for high-speed interconnect. It integrates dual-register 6-input LUTs, carry chains for arithmetic, and clock management tiles with DCMs and PLLs.
Its RocketIO GTP transceivers support serial protocols including SATA, Serial RapidIO, and CPRI. Configuration is performed via Master SelectMAP mode using external flash or through JTAG boundary-scan, with bitstream encryption optional via AES-256.
