AMD XC6SLX25-2FG484I

Overview

XC6SLX25-2FG484I from AMD (formerly Xilinx) is a Spartan-6 FPGA with 24,051 logic cells, 1.8 V core voltage, -2 speed grade, and 484-pin Fine-Pitch Ball Grid Array (FBGA) package. It integrates 92 DSP48E slices, 1,824 Kbits of block RAM, and supports LVDS, SSTL, and HSTL I/O standards for high-speed interface design in industrial control systems.

For engineers reviewing the XC6SLX25-2FG484I datasheet, pinout, applications, or equivalent options, key selection criteria include logic capacity, I/O bank voltage flexibility, embedded memory depth, and support for PCIe Gen1 endpoint configurations.

Technical Context

The XC6SLX25-2FG484I implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic for arithmetic functions. It includes dual-register 6-input LUTs, distributed RAM, and shift registers per CLB.

It features six CMT clock management tiles-each with two DCMs and one PLL-for multi-phase clock synthesis, jitter reduction, and frequency translation across up to 16 user clocks. I/O banks support independent voltage operation (1.2 V to 3.3 V) with programmable slew rate and drive strength.

FAQ

What is the maximum supported I/O standard voltage for XC6SLX25-2FG484I?

XC6SLX25-2FG484I supports I/O voltages from 1.2 V to 3.3 V across eight independent banks. Each bank's VCCO can be set individually, enabling concurrent LVCMOS33, LVCMOS25, and HSTL_I interfaces without external level shifters. The XC6SLX25-2FG484I datasheet specifies absolute maximum ratings and DC characteristics per IOSTANDARD parameter in UG381.

Does XC6SLX25-2FG484I include built-in configuration memory?

No, XC6SLX25-2FG484I does not include on-chip non-volatile configuration memory. It relies on external serial flash (e.g., Micron MT25QL series) or PROM for bitstream storage. Configuration occurs via Master SPI, Slave SelectMAP, or JTAG mode. The XC6SLX25-2FG484I requires external power sequencing and configuration clock sources as defined in DS162.

Can XC6SLX25-2FG484I operate in industrial temperature range?

Yes, the "I" suffix in XC6SLX25-2FG484I denotes Industrial temperature grade (-40°C to +100°C junction). Thermal performance depends on PCB layout, airflow, and power dissipation. Xilinx UG381 specifies thermal resistance values (θJA = 22.5°C/W typical) and recommends 4-layer boards with thermal vias under the FG484 package for reliable operation at max ambient.

What clock resources are available in XC6SLX25-2FG484I?

XC6SLX25-2FG484I contains six Clock Management Tiles (CMTs), each with two Digital Clock Managers (DCMs) and one Phase-Locked Loop (PLL). These support frequency synthesis, phase shifting, duty-cycle correction, and spread-spectrum clocking. The XC6SLX25-2FG484I supports up to 16 globally routed clocks and allows dynamic reconfiguration of DCM/PLL parameters via internal control registers.

Is XC6SLX25-2FG484I compatible with Vivado Design Suite?

No, XC6SLX25-2FG484I is supported exclusively by Xilinx ISE Design Suite v14.7 (final release). Vivado does not support Spartan-6 devices. Migration to newer families like Artix-7 requires redesign and toolchain transition. For ongoing maintenance, XC6SLX25-2FG484I projects must use ISE 14.7 with associated service packs and license files.
