AMD XC4003E-2PG120I

Overview

XC4003E-2PG120I from Xilinx is a 3,000-gate Field-Programmable Gate Array (FPGA) in a 120-pin plastic quad flat pack (PQFP), featuring 83 user I/O pins, 3.3 V I/O compatibility, and -2 speed grade (15 ns CLB propagation delay). It targets low-complexity digital logic replacement in industrial control and legacy system upgrades.

For engineers reviewing the XC4003E-2PG120I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count, speed grade, package thermal profile, and configuration memory retention requirements.

Technical Context

The XC4003E-2PG120I implements configurable logic blocks (CLBs) with look-up table (LUT)-based combinatorial logic and flip-flop-based sequential elements. It supports SRAM-based configuration with external serial PROM or parallel programming via JTAG boundary-scan interface.

It operates within an industrial temperature range (–40°C to +85°C), uses 5 V core supply with 3.3 V tolerant I/Os, and requires external configuration circuitry for power-on initialization. No internal oscillator or configuration memory is integrated.

Manufacturer

Xilinx, now part of AMD, pioneered commercial FPGA technology and developed the XC4000E family as a cost-optimized, high-reliability solution for industrial and aerospace logic consolidation.

The XC4000E product line was designed specifically for drop-in replacement of TTL/PLD logic in long-lifecycle systems where reprogrammability, I/O flexibility, and industrial temperature operation were essential.

FAQ

What is the configuration method supported by XC4003E-2PG120I?

XC4003E-2PG120I supports serial configuration via the DIN pin using an external PROM and parallel configuration through the JTAG boundary-scan interface. It does not include on-chip configuration memory and requires external nonvolatile storage for power-up initialization. The PROGRAM pin enables synchronous reconfiguration. XC4003E-2PG120I does not support master serial or slave parallel modes without external controller logic.

Does XC4003E-2PG120I support hot-swap or live insertion?

No, XC4003E-2PG120I is not rated for hot-swap operation. Its I/O structure lacks bus-hold or precharge circuitry, and power sequencing requirements mandate that VCC be stable before applying signals to I/O pins. Applying inputs before power-up may cause latch-up or parametric failure. XC4003E-2PG120I must be powered and initialized before engaging with live system buses.

What is the maximum clock frequency achievable with XC4003E-2PG120I?

The maximum system clock frequency depends on design topology, but the -2 speed grade guarantees ≤15 ns propagation delay through a single CLB. In register-to-register paths with optimal placement, XC4003E-2PG120I achieves up to 66 MHz. Actual frequency is constrained by routing delays and fanout; timing analysis must be performed per implementation. XC4003E-2PG120I does not include dedicated PLLs or DLLs for clock multiplication.

Can XC4003E-2PG120I operate with a 3.3 V core supply?

No, XC4003E-2PG120I requires a 5 V core supply (VCC) and is not functional at 3.3 V. Its I/Os are 3.3 V tolerant, allowing connection to 3.3 V peripherals, but internal logic cells require 5 V for correct LUT and flip-flop operation. Using 3.3 V on VCC will result in undefined behavior or complete failure. XC4003E-2PG120I must be powered with regulated 5 V ±5%.

Is XC4003E-2PG120I RoHS compliant?

XC4003E-2PG120I was manufactured prior to RoHS Directive enforcement and contains leaded solder in its 120-pin PQFP package. It is classified as a legacy non-RoHS component. For new designs requiring RoHS compliance, consider migration to Spartan-3 or later families. XC4003E-2PG120I remains available for repair and legacy production under exemption clauses.
