AMD XC4003E-3VQ100C

Overview

XC4003E-3VQ100C from Xilinx is a Field-Programmable Gate Array (FPGA) with 3,000 usable gates, 100-pin VQFP package, 3.3 V supply voltage, and -3 speed grade (12 ns propagation delay). It implements synchronous digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4003E-3VQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (84 user I/Os), VQFP thermal and routing constraints, speed-grade timing compliance, and legacy 5 V-tolerant I/O support.

Technical Context

The XC4003E-3VQ100C belongs to Xilinx's XC4000E FPGA family, built on 0.5 µm CMOS technology. It features configurable logic blocks (CLBs), input/output blocks (IOBs), and programmable interconnect resources. Configuration is performed via serial or parallel mode using external PROM or microprocessor.

It supports IEEE Std 1149.1 (JTAG) boundary-scan testing and includes dedicated carry logic for high-speed arithmetic. The device operates over commercial temperature range (0°C to +70°C) and requires external configuration memory.

FAQ

What is the maximum operating frequency supported by XC4003E-3VQ100C?

The XC4003E-3VQ100C has a -3 speed grade specifying a 12 ns CLB-to-CLB propagation delay. Its maximum system clock frequency depends on design topology but typically supports up to 66 MHz for fully registered paths. Actual achievable frequency must be verified post-place-and-route using Xilinx Foundation or Alliance software timing analysis for the XC4003E-3VQ100C.

Does XC4003E-3VQ100C support in-system programming (ISP)?

No, the XC4003E-3VQ100C does not support true in-system programming. It requires external configuration PROM or microprocessor-controlled parallel/serial loading at power-up. While JTAG boundary-scan is present for testing, configuration bitstream cannot be rewritten in-system without full reinitialization of the XC4003E-3VQ100C.

What are the power supply requirements for XC4003E-3VQ100C?

The XC4003E-3VQ100C requires two dedicated supplies: VCCINT = 3.3 V ± 5% for core logic, and VCCO = 3.3 V for I/O banks. All VCCINT and VCCO pins must be individually decoupled with 0.1 µF ceramic capacitors placed within 1 cm. Ground connections (GND pins) must be low-inductance and distributed evenly around the XC4003E-3VQ100C perimeter.

Is XC4003E-3VQ100C RoHS compliant?

The XC4003E-3VQ100C is not RoHS compliant. It was manufactured prior to RoHS Directive enforcement and contains lead in its solder finish and die attach. For RoHS-compliant alternatives, consider later-generation Spartan or Artix families - the XC4003E-3VQ100C remains available for legacy repair and long-lifecycle industrial use under exemption clauses.

Can XC4003E-3VQ100C interface directly with 5 V logic devices?

Yes, the XC4003E-3VQ100C IOBs support 5 V-tolerant inputs, allowing direct connection to 5 V TTL or CMOS outputs without level shifters. However, its outputs swing to 3.3 V, so driving 5 V inputs requires external pull-up resistors or buffer ICs. This dual-voltage capability is explicitly specified in the XC4003E-3VQ100C datasheet for all user I/O pins.
