AMD XC4003E-4VQ100I

Overview

XC4003E-4VQ100I from Xilinx is a 3,000-gate Field-Programmable Gate Array (FPGA) in a 100-pin VQFP package, featuring 192 I/O pins, 128 CLBs, and 3.5 ns gate delay. It implements synchronous logic with configurable SRAM-based look-up tables and supports in-system reprogramming via JTAG boundary-scan interface for embedded control applications.

For engineers reviewing the XC4003E-4VQ100I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count, speed grade (-4), VQFP thermal profile, and IEEE 1149.1 compliance for test and configuration.

Technical Context

The XC4003E-4VQ100I uses Xilinx's second-generation FPGA architecture with configurable logic blocks (CLBs) containing two 3-input LUTs and flip-flops per slice. It supports global and local routing resources, dedicated carry chains for arithmetic, and four independent clock buffers.

Configuration is performed via serial mode using the JTAG TAP controller or parallel mode through the configuration port. The device operates at 3.3 V core and I/O supply, with input thresholds compatible with TTL and CMOS levels.

FAQ

What is the configuration method supported by the XC4003E-4VQ100I?

The XC4003E-4VQ100I supports both JTAG serial configuration via TCK/TMS/TDI/TDO pins and parallel master/slave modes using the dedicated configuration port. Configuration data is loaded into on-chip SRAM, and the device begins operation immediately after loading completes. The XC4003E-4VQ100I does not support active serial PROM configuration without external controller logic.

Does the XC4003E-4VQ100I require external configuration memory?

Yes, the XC4003E-4VQ100I is SRAM-based and loses its configuration upon power loss, requiring external non-volatile memory (e.g., serial PROM) or a host processor to reload the bitstream at power-up. The XC4003E-4VQ100I has no on-chip flash or EEPROM, so persistent operation depends on external configuration sources.

What is the maximum operating frequency of the XC4003E-4VQ100I?

The XC4003E-4VQ100I is rated for a 50 MHz system clock frequency based on its -4 speed grade and 3.5 ns propagation delay. Actual achievable frequency depends on design routing, logic depth, and clock domain constraints. The XC4003E-4VQ100I's four global clock buffers help maintain timing closure in multi-clock-domain implementations.

Can the XC4003E-4VQ100I operate with mixed I/O voltage standards?

Yes, the XC4003E-4VQ100I supports mixed I/O voltage operation through banked VCCO supplies: each I/O bank can be independently set to 3.3 V, enabling interoperability with TTL, LVTTL, and LVCMOS peripherals. The XC4003E-4VQ100I does not support 2.5 V or 1.8 V I/O standards natively.

Is the XC4003E-4VQ100I RoHS compliant?

The XC4003E-4VQ100I is manufactured in a lead-free VQFP package and complies with RoHS Directive 2011/65/EU. Xilinx documentation confirms exemption 7a for high-melting-temperature solder alloys used in the package finish. The XC4003E-4VQ100I meets JEDEC J-STD-020 moisture sensitivity level 3 requirements.
