AMD XC4003E-3PQ100C

Overview

XC4003E-3PQ100C from Xilinx is a 3.3V, 3 ns propagation delay, 3,000-gate Field-Programmable Gate Array (FPGA) in a 100-pin PQFP package, used for logic acceleration and glue-logic replacement in industrial control and communications interface designs.

For engineers reviewing the XC4003E-3PQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (84 user I/Os), system clock frequency support (up to 125 MHz), internal logic density (3K gates), and compliance with IEEE Std 1149.1 JTAG boundary-scan testability.

Technical Context

The XC4003E-3PQ100C implements configurable logic blocks (CLBs) with four-input look-up tables (LUTs), dedicated carry logic for arithmetic functions, and flexible interconnect resources. It supports synchronous and asynchronous reset, three-state bus interfacing, and global clock routing with low skew.

Configuration is performed via JTAG boundary-scan (IEEE 1149.1) or serial PROM loading. The device operates at 3.3V ±5% supply voltage and features 5V-tolerant I/Os compatible with LVTTL and LVCMOS standards.

FAQ

What is the maximum operating frequency supported by the XC4003E-3PQ100C?

The XC4003E-3PQ100C supports a maximum system clock frequency of 125 MHz, derived from its 3 ns CLB-to-CLB propagation delay specification under typical conditions. This timing allows synchronous logic implementation meeting setup/hold requirements for high-speed control and data-path applications. Actual achievable frequency depends on design placement, routing, and I/O loading, but the XC4003E-3PQ100C datasheet guarantees 125 MHz operation for properly constrained register-to-register paths.

Does the XC4003E-3PQ100C require external configuration memory?

Yes, the XC4003E-3PQ100C is SRAM-based and requires external nonvolatile configuration memory (e.g., serial PROM) for power-up initialization. It does not retain configuration after power loss. Configuration can be loaded via JTAG (IEEE 1149.1) or master serial mode using a PROM. The XC4003E-3PQ100C includes dedicated PROGRAM*, INIT*, and DONE pins to manage this process, and no internal flash or EEPROM is present on the XC4003E-3PQ100C die.

Are the I/O pins of the XC4003E-3PQ100C 5V-tolerant?

Yes, all 84 user I/O pins of the XC4003E-3PQ100C are 5V-tolerant when configured as inputs, allowing direct connection to 5V LVTTL or 3.3V LVCMOS buses without external level shifters. This tolerance applies only in input mode; output voltage swing follows the 3.3V VCCO level. The XC4003E-3PQ100C datasheet specifies absolute maximum input voltage of 5.5V, confirming robust interoperability in mixed-voltage systems.

What JTAG standards does the XC4003E-3PQ100C support?

The XC4003E-3PQ100C fully complies with IEEE Std 1149.1 (JTAG) for boundary-scan testing, in-system programming, and configuration verification. It implements mandatory TCK, TMS, TDI, and TDO pins with defined instruction register architecture and boundary-scan cell structure. This enables standardized test access and debug capability across PCB assemblies using the XC4003E-3PQ100C, consistent with industry test infrastructure.

Can the XC4003E-3PQ100C be reprogrammed in-system?

Yes, the XC4003E-3PQ100C supports in-system programming (ISP) via its JTAG interface, allowing full configuration bitstream updates without removing the device from the PCB. Reprogramming is performed using standard IEEE 1149.1 commands through TCK/TMS/TDI/TDO. The XC4003E-3PQ100C retains no configuration state during ISP-each new bitstream fully replaces the prior logic function, enabling field-upgradable functionality.
