Product details
Overview
XC3S250E-5PQG208C from AMD (formerly Xilinx) is a Spartan-3E FPGA with 250,000 system gates, 4,992 logic cells, 228 I/O pins, and embedded block RAM totaling 256 Kbits. It operates at 500 MHz system clock speed and targets low-cost, high-volume embedded control and interface bridging applications.
For engineers reviewing the XC3S250E-5PQG208C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count, embedded RAM depth, LVCMOS33/LVDS I/O support, and -5 speed grade timing compliance for real-time logic implementation.
Technical Context
The XC3S250E-5PQG208C implements a configurable logic fabric based on 4-input LUTs and distributed RAM, with dedicated carry chains for arithmetic. It integrates twelve 18×18 multipliers and supports SelectIO standards including LVCMOS, LVTTL, PCI, and LVDS.
Configuration is performed via master serial mode using external PROM or JTAG, and the device supports full IEEE 1149.1 boundary-scan testing. Internal global clock networks distribute up to eight user-defined clocks with low skew.

Yes, the XC3S250E-5PQG208C fully supports IEEE 1149.1 JTAG boundary-scan for configuration, debugging, and board-level test. Pins TCK, TMS, TDI, and TDO are dedicated to this interface and remain functional regardless of configuration mode selected via M0–M2 pins.
What I/O standards are supported by the XC3S250E-5PQG208C?
The XC3S250E-5PQG208C supports LVCMOS33, LVCMOS25, LVTTL, PCI, and LVDS I/O standards across its 228 configurable pins. Each I/O bank operates independently with selectable VCCO and optional VREF, enabling mixed-voltage interface designs without level shifters.
How much embedded memory does the XC3S250E-5PQG208C provide?
The XC3S250E-5PQG208C contains 256 Kbits of total embedded block RAM, organized as thirty-two 8 Kbit blocks. These support synchronous read/write, true dual-port access, and byte-write enable-ideal for FIFOs, frame buffers, and coefficient storage in signal processing pipelines.
Is the XC3S250E-5PQG208C still in active production?
XC3S250E-5PQG208C is currently available through AMD's legacy product support program and authorized distributors. While not part of AMD's newest FPGA roadmap, it remains actively stocked and supported for long-lifecycle industrial and medical applications with documented obsolescence timelines.
