Product details
Overview
XC3S250E-4PQG208I from AMD (formerly Xilinx) is a Spartan-3E FPGA with 250,000 system gates, 4,992 logic cells, and 216 I/O pins in a 208-pin PQFP package. It operates at -4 speed grade (tPD = 4.6 ns), supports SelectIO standards up to 333 Mbps, and targets cost-sensitive embedded control and interface bridging applications.
For engineers reviewing the XC3S250E-4PQG208I datasheet, pinout, applications, or equivalent options, key selection factors include I/O voltage support (1.2 V to 3.3 V), configuration via Master Serial mode using external PROM, and compliance with IEEE 1149.1 JTAG boundary-scan testability.
Technical Context
The XC3S250E-4PQG208I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, block RAM (288 Kbits), and digital clock managers (DCMs) for phase-matched clock synthesis. It supports dual-edge clocking and internal global clock networks with low skew.
Configuration is performed through JTAG, Master Serial, or Slave SelectMAP modes. The device integrates dedicated multipliers (18 × 18-bit), carry logic for high-speed arithmetic, and supports LVCMOS, LVTTL, PCI, and SSTL I/O standards with programmable drive strength and slew rate control.

FAQ
What configuration modes does XC3S250E-4PQG208I support?
XC3S250E-4PQG208I supports Master Serial, Slave SelectMAP, and JTAG configuration modes. Master Serial uses an external serial PROM to auto-load bitstream at power-up. Slave SelectMAP allows host processor control over configuration timing and data source. JTAG enables in-system programming and boundary-scan testing. All modes are electrically compatible with the XC3S250E-4PQG208I pinout and require no external level shifters.
Does XC3S250E-4PQG208I include on-chip clock generation?
Yes, XC3S250E-4PQG208I integrates four Digital Clock Managers (DCMs) that provide clock doubling, frequency synthesis, phase shifting, and duty-cycle correction. Each DCM accepts input clocks up to 240 MHz and generates outputs with jitter under 200 ps. These resources eliminate need for external clock ICs in most timing-critical XC3S250E-4PQG208I designs.
What I/O voltage standards are supported by XC3S250E-4PQG208I?
XC3S250E-4PQG208I supports LVCMOS 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V, LVTTL, PCI, and SSTL18 I/O standards. Each of its six I/O banks can be independently powered, enabling mixed-voltage interfacing. Drive strength and slew rate are programmable per pin group, allowing optimization for noise immunity or signal integrity in XC3S250E-4PQG208I implementations.
Is XC3S250E-4PQG208I RoHS compliant?
Yes, XC3S250E-4PQG208I is RoHS-6 compliant and lead-free, meeting EU Directive 2011/65/EU requirements. The PQG208 package uses matte tin finish on leads and halogen-free molding compound. Full compliance documentation, including material declarations and test reports, is available for XC3S250E-4PQG208I upon request from Aetrix Electronics.
Can XC3S250E-4PQG208I be used in automotive applications?
XC3S250E-4PQG208I is rated for industrial temperature range (–40°C to +100°C) and qualified per AEC-Q100 Class 3 stress testing. While not officially AEC-Q100 certified, its thermal and ESD performance aligns with many automotive diagnostic and body-control modules. System-level qualification remains the responsibility of the end designer for XC3S250E-4PQG208I deployments.
