Product details
Overview
XC4VLX15-10FF668I from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA featuring 15,856 logic cells, 1.2 Mb of block RAM, and 128 DSP48 slices. It uses a 668-pin Fine-Pitch Flip-Chip BGA (FF668) package with 3.3 V/2.5 V/1.2 V I/O and core voltage support, deployed in high-speed communication line cards and reconfigurable computing platforms.
For engineers reviewing the XC4VLX15-10FF668I datasheet, pinout, applications, or equivalent options, key selection factors include speed grade (-10), I/O count (448 user I/Os), differential signaling support (LVDS, RSDS), embedded memory depth, and DSP slice count for algorithm acceleration.
Technical Context
The XC4VLX15-10FF668I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated carry chains, and distributed RAM. It integrates SelectIO technology supporting single-ended (LVTTL, LVCMOS) and differential (LVDS, RSDS, BLVDS) standards up to 840 Mbps per differential pair.
It includes 128 hard-wired 18×18-bit signed multipliers in DSP48 slices, each capable of 18-bit multiplication or accumulation. The device supports partial reconfiguration and features dedicated clock management tiles with DCMs (Digital Clock Managers) for phase alignment, frequency synthesis, and duty-cycle correction.
