AMD XC4003E-2VQ100C

Overview

XC4003E-2VQ100C from Xilinx is a Field-Programmable Gate Array (FPGA) with 3,000 usable gates, 100-pin VQFP package, -2 speed grade (12.5 ns propagation delay), and embedded SRAM-based configuration memory. It serves as a reconfigurable logic fabric in digital control systems for industrial motion controllers.

For engineers reviewing the XC4003E-2VQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (84 user I/Os), speed grade timing compliance, VQFP thermal and routing constraints, and legacy 5 V tolerant I/O support.

Technical Context

The XC4003E-2VQ100C implements a hierarchical CLB (Configurable Logic Block) architecture with four-input LUTs and flip-flops per CLB, supporting synchronous sequential logic design. It uses SRAM-based configuration cells loaded at power-up via external PROM or microcontroller interface.

It supports 5 V TTL-compatible I/O standards with programmable slew rate and drive strength, and includes dedicated global clock and reset routing networks. Configuration is performed through JTAG boundary-scan or master serial mode using Xilinx's XC1700-series PROMs.

FAQ

What is the maximum operating frequency supported by XC4003E-2VQ100C?

The XC4003E-2VQ100C has a -2 speed grade specifying a 12.5 ns CLB propagation delay, enabling reliable synchronous operation up to 40 MHz for register-to-register paths. Actual system frequency depends on design topology, placement, and routing; timing analysis must be performed using Xilinx Foundation or Alliance software targeting the XC4003E-2VQ100C device model.

Does XC4003E-2VQ100C support in-system programming?

Yes, XC4003E-2VQ100C supports in-system programming via its JTAG port (IEEE 1149.1 compliant) or serial configuration mode using an external PROM. The device retains no configuration state on power loss and requires reconfiguration at startup, which can be automated using microcontroller-driven serial loading sequences targeting the XC4003E-2VQ100C.

What power supply voltages does XC4003E-2VQ100C require?

XC4003E-2VQ100C requires a single 5.0 V ±10% supply for both core logic (VCCINT) and I/O banks (VCCIO). All 84 user I/Os are 5 V tolerant, eliminating need for separate I/O voltage rails. Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum per VCC/GND pair) are mandatory per Xilinx XC4000E design guidelines for stable XC4003E-2VQ100C operation.

Is XC4003E-2VQ100C RoHS compliant?

No, XC4003E-2VQ100C is a legacy device manufactured prior to RoHS Directive 2002/95/EC enforcement and contains leaded solder in its VQFP package. It is exempt under RoHS Annex III for industrial monitoring and control equipment under specific application conditions, but formal exemption documentation must be obtained from AMD/Xilinx for compliance validation in regulated deployments of XC4003E-2VQ100C.

Can XC4003E-2VQ100C replace discrete 74-series logic in existing designs?

Yes, XC4003E-2VQ100C is frequently used to consolidate multiple 74HC/74LS ICs into a single reprogrammable device. Its 5 V I/O compatibility, predictable timing, and pin-per-pin routability in VQFP-100 allow direct substitution in legacy schematics - provided the original design fits within 3,000 gates and 84 I/Os, and configuration memory (e.g., XC1736) is added for XC4003E-2VQ100C startup.
