AMD XC4005XL-1PQ208I

Overview

XC4005XL-1PQ208I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 192 I/O pins, and a 10 ns system gate delay, configured in a 208-pin Plastic Quad Flat Package (PQFP). It implements synchronous digital logic for embedded control, interface bridging, and protocol conversion in industrial PLCs and test equipment.

For engineers reviewing the XC4005XL-1PQ208I datasheet, pinout, applications, or equivalent options, key selection factors include gate count, I/O count, speed grade (-1), package thermal profile, and compatibility with Xilinx Foundation Series design tools.

Technical Context

This FPGA uses Xilinx's XC4000XL architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports 3.3 V I/O operation and includes dedicated carry logic for arithmetic functions.

The -1 speed grade indicates a 10 ns maximum propagation delay for CLB-to-CLB paths. Configuration is performed via serial mode using an external PROM or parallel mode through the JTAG boundary-scan interface compliant with IEEE 1149.1.

Manufacturer

Xilinx, now part of AMD, pioneered commercial FPGA technology and provides comprehensive design tools, IP libraries, and silicon solutions for programmable logic applications.

The XC4000XL family was engineered for cost-sensitive, low-power embedded control and interface logic, targeting applications where 3.3 V operation and predictable timing behavior were critical.

FAQ

What is the maximum operating frequency supported by XC4005XL-1PQ208I?

The XC4005XL-1PQ208I has a -1 speed grade specifying a 10 ns CLB-to-CLB propagation delay. This translates to a theoretical maximum system clock frequency of approximately 100 MHz for simple register-to-register paths. Actual achievable frequency depends on design topology, routing, and I/O timing constraints.

Does XC4005XL-1PQ208I support in-system programming via JTAG?

Yes, XC4005XL-1PQ208I fully complies with IEEE 1149.1 and supports boundary-scan testing and in-system configuration through its TMS, TDI, TDO, and TCK pins. JTAG mode enables programming without removing the device from the PCB.

Can XC4005XL-1PQ208I operate with mixed I/O voltage standards?

Yes, XC4005XL-1PQ208I features eight independent I/O banks (VCCO_0 through VCCO_7), each configurable for 3.3 V operation. While all banks require 3.3 V, they can be assigned different I/O standards (LVTTL, LVCMOS) and drive strengths per bank.

What configuration memory is required for XC4005XL-1PQ208I in serial mode?

In master serial configuration mode, XC4005XL-1PQ208I requires an external serial PROM such as Xilinx XC18V02 or compatible 2 Mbit SPI flash. The PROM stores the configuration bitstream and automatically loads it on power-up via the DIN pin.

Is XC4005XL-1PQ208I RoHS compliant?

XC4005XL-1PQ208I was manufactured prior to mandatory RoHS enforcement and is not RoHS compliant. It contains lead in the solder finish and packaging materials. For new designs, consider migration paths to RoHS-compliant alternatives or consult AMD/Xilinx for legacy compliance documentation.
