AMD XC4005E-4PQ100I

Overview

XC4005E-4PQ100I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 100-pin Plastic Quad Flat Package (PQFP), and -4 speed grade (15 ns CLB propagation delay). It implements synchronous logic in digital systems requiring reconfigurable logic fabric, embedded control, and glue logic replacement in industrial controllers and communication interfaces.

For engineers reviewing the XC4005E-4PQ100I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (84 user I/Os), speed grade (-4), configuration mode (serial PROM or parallel), and compatibility with Xilinx Foundation or Alliance software tools.

Technical Context

The XC4005E-4PQ100I belongs to the Xilinx XC4000E family, built on 0.5 µm CMOS technology with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports both serial and parallel configuration modes and uses SRAM-based configuration memory.

It features dedicated carry logic for high-speed arithmetic, global clock routing networks, and three-state bus interface capability. Configuration is volatile and requires external PROM or processor-controlled loading at power-up.

Key Specifications

Pinout & Package

FAQ

What is the configuration method supported by XC4005E-4PQ100I?

XC4005E-4PQ100I supports both master serial and slave parallel configuration modes. In master serial mode, it loads configuration data from an external PROM via DIN; in slave parallel mode, a microprocessor writes the bitstream directly to the device. Configuration is volatile and must be repeated at each power-on cycle. XC4005E-4PQ100I does not support JTAG-only configuration without external initialization logic.

Does XC4005E-4PQ100I have internal voltage regulation?

No, XC4005E-4PQ100I requires a clean, regulated 5.0 V ± 5% supply applied directly to its VCC pins. It lacks on-chip regulators or voltage translators. Decoupling capacitors (0.1 µF ceramic per power pin) are mandatory near each VCC/GND pair to suppress switching noise. XC4005E-4PQ100I draws dynamic current dependent on toggle rate and configured logic density.

Can XC4005E-4PQ100I operate in industrial temperature range?

Yes, the "I" suffix in XC4005E-4PQ100I denotes industrial temperature grade (-40°C to +85°C). This rating applies to the full operating range under specified VCC and loading conditions. Thermal performance depends on PCB copper area, airflow, and adjacent heat sources. XC4005E-4PQ100I's PQFP package has a θ_JA of approximately 45°C/W under standard JEDEC conditions.

Is XC4005E-4PQ100I pin-compatible with other XC4000E devices?

XC4005E-4PQ100I is pin-compatible only with other XC4000E family members in the same PQ100 package, such as XC4003E-4PQ100I or XC4006E-4PQ100I. Pin compatibility assumes identical speed grade and configuration mode settings. XC4005E-4PQ100I is not compatible with XC4000XL or Spartan families due to differing IOB structures and configuration protocols.

What software tools support XC4005E-4PQ100I design flow?

XC4005E-4PQ100I is supported by Xilinx Foundation Series 2.x and Alliance Series 2.x software suites, including schematic capture, HDL synthesis (VHDL/Verilog), place-and-route, and bitstream generation. Timing analysis uses Xilinx Timing Analyzer with device-specific libraries. XC4005E-4PQ100I does not support newer ISE or Vivado toolchains.
