AMD XC4005E-1PQ100C

Overview

XC4005E-1PQ100C from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 100-pin Plastic Quad Flat Package (PQFP), -1 speed grade (10 ns CLB propagation delay), and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control, protocol bridging, and glue-logic replacement applications.

For engineers reviewing the XC4005E-1PQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (84 user I/Os), speed grade timing, PQFP thermal and routing constraints, and legacy 5 V CMOS compatibility.

Technical Context

The XC4005E-1PQ100C belongs to Xilinx's XC4000E FPGA family, built on 0.5 µm CMOS technology. It contains 192 Configurable Logic Blocks (CLBs), each with two 3-input LUTs and flip-flops, and supports SRAM-based configuration via JTAG or serial PROM.

It features dedicated carry logic for high-speed arithmetic, global clock buffers, and three-state bus interface support. Configuration is volatile and requires external PROM loading at power-up.

Key Specifications

Pinout & Package

XC4005E-1PQ100C uses a 100-lead Plastic Quad Flat Package (PQFP) with 24 pins per side, 0.65 mm lead pitch, and 20.0 mm × 20.0 mm body size. Thermal dissipation is managed via PCB copper area under the exposed pad (if present) and perimeter leads.

FAQ

What is the configuration method supported by the XC4005E-1PQ100C?

The XC4005E-1PQ100C supports master serial, slave serial, and JTAG configuration modes. It loads configuration bitstream from external PROM via DIN pin in master serial mode, or accepts data from a controller in slave serial mode. JTAG enables boundary-scan testing and in-system programming without dedicated configuration hardware. The XC4005E-1PQ100C does not support configuration from processor memory-mapped writes.

Does the XC4005E-1PQ100C support mixed-voltage I/O operation?

No, the XC4005E-1PQ100C operates exclusively at 5.0 V and does not support mixed-voltage I/O banks. All I/O pins share the same VCCIO supply, which is tied to the core VCC. Level translation for interfacing with 3.3 V or lower devices must be implemented externally using discrete buffers or translators. This constraint applies uniformly across all XC4005E-1PQ100C units.

What is the maximum operating frequency achievable with the XC4005E-1PQ100C?

The XC4005E-1PQ100C has a -1 speed grade specifying 10 ns CLB propagation delay, enabling reliable operation up to approximately 66 MHz for fully registered designs with balanced routing. Actual maximum frequency depends on design topology, placement, and routing; Xilinx Foundation software reports timing analysis results based on the implemented netlist. The XC4005E-1PQ100C does not guarantee performance beyond its characterized speed grade.

Is the XC4005E-1PQ100C RoHS compliant?

The XC4005E-1PQ100C is not RoHS compliant. It contains lead in the solder finish and packaging materials, consistent with pre-RoHS manufacturing standards for the XC4000E family. Devices shipped prior to July 2006 fall outside EU RoHS Directive 2002/95/EC scope. For RoHS-compliant alternatives, consult AMD/Xilinx documentation for later-generation Spartan or Artix families.

Can the XC4005E-1PQ100C be reconfigured in-system without power cycling?

Yes, the XC4005E-1PQ100C supports in-system reconfiguration via its PROGRAM pin and serial configuration interface. Asserting PROGRAM low followed by reloading the bitstream through DIN allows full logic redefinition while powered. This capability is used for field upgrades and multi-function mode switching. The XC4005E-1PQ100C retains no configuration state during PROGRAM assertion and requires complete bitstream reload.
