Product details
Overview
XC6SLX25-3FT256C from AMD (formerly Xilinx) is a Spartan-6 FPGA with 24,051 logic cells, 18 Kbits of block RAM, and 186 user I/Os in a 256-pin FTBGA package. It operates at -3 speed grade (1.2 V core, industrial temperature range) and supports LVCMOS/LVDS interfaces for embedded control and digital signal processing.
For engineers reviewing the XC6SLX25-3FT256C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count, speed grade timing closure, and compatibility with Spartan-6 design toolchains and reference clocking schemes.
Technical Context
The XC6SLX25-3FT256C implements a hierarchical FPGA architecture with six-input LUTs, distributed RAM, and dedicated DSP48A1 slices supporting 18×18-bit multiply-accumulate operations. It integrates dual-clock DDR memory controllers and supports configuration via SPI, BPI, or JTAG.
It features SelectIO technology with programmable drive strength, slew rate, and on-chip termination for 1.2–3.3 V I/O standards. The device includes internal clock management using DCMs (Digital Clock Managers) with phase shifting and frequency synthesis capabilities.
