AMD XC3S200-4VQ100C

Overview

XC3S200-4VQ100C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 200,000 system gates, 4,320 logic cells, 173 I/O pins, and configured in a 100-pin VQFP package. It operates at -4 speed grade (5 ns CLB delay), supports SelectIO standards including LVCMOS, LVTTL, and PCI, and is used in industrial control logic and embedded interface bridging.

For engineers reviewing the XC3S200-4VQ100C datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count, speed grade timing closure, and VQFP thermal and routing constraints for cost-sensitive reprogrammable logic designs.

Technical Context

The XC3S200-4VQ100C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, block RAM (48 Kbits), and dedicated multipliers. It integrates Digital Clock Managers (DCMs) for clock synthesis, phase shifting, and jitter reduction across up to four independent clock domains.

Configuration is performed via Master Serial mode using external PROM or JTAG boundary-scan. The device supports IEEE 1149.1 compliance and includes internal pull-up resistors on configuration pins, programmable I/O drive strength (2–24 mA), and slew rate control per bank.

Key Specifications

Pinout & Package

VQFP-100 (Very Thin Quad Flat Pack) is a 100-lead, 14 mm × 14 mm, 0.5 mm pitch surface-mount package with gull-wing leads. Thermal performance relies on PCB copper area under the body; no thermal pad is integrated.

FAQ

What is the maximum operating frequency supported by the XC3S200-4VQ100C?

The XC3S200-4VQ100C supports a maximum system clock frequency of 280 MHz when using its Digital Clock Managers (DCMs) for internal clock multiplication. Its -4 speed grade guarantees 5 ns CLB propagation delay, enabling reliable operation in synchronous designs with critical paths meeting this timing constraint. Actual achievable frequency depends on design topology, placement, and routing.

Does the XC3S200-4VQ100C support JTAG boundary-scan testing?

Yes, the XC3S200-4VQ100C fully complies with IEEE 1149.1 (JTAG) standards. It supports boundary-scan testing, in-system programming, and debug access via TCK, TMS, TDI, and TDO pins. This capability enables verification of PCB interconnects and facilitates configuration debugging without requiring external programming hardware.

Can the XC3S200-4VQ100C be reconfigured in-system after power-up?

Yes, the XC3S200-4VQ100C supports in-system reconfiguration through its PROGRAM_B and INIT_B pins. Using Master Serial mode with an external PROM or JTAG interface, the device can reload its configuration bitstream dynamically. This enables field-upgradable logic functionality without physical replacement of the XC3S200-4VQ100C.

What I/O standards are supported by the XC3S200-4VQ100C?

The XC3S200-4VQ100C supports multiple I/O standards per bank, including LVCMOS (3.3 V, 2.5 V, 1.8 V), LVTTL, PCI, and SSTL-2. Each I/O bank is independently configurable for voltage level and drive strength (2–24 mA), allowing mixed-voltage interfacing on a single XC3S200-4VQ100C device.

Is the XC3S200-4VQ100C RoHS compliant?

Yes, the XC3S200-4VQ100C is RoHS compliant and lead-free. It meets EU Directive 2011/65/EU requirements, with all homogeneous materials containing ≤0.1 wt% lead (except exempted categories). Full compliance documentation is available in AMD's official product change notifications for the Spartan-3 family.
