AMD XC4005E-2PC84I

Overview

XC4005E-2PC84I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, -2 speed grade (12.5 ns maximum input-to-output delay), and industrial temperature range (-40°C to +85°C). It implements synchronous digital logic for embedded control and interface bridging in legacy industrial systems.

For engineers reviewing the XC4005E-2PC84I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (69 user I/Os), speed grade timing, PLCC-84 mechanical compatibility, and Xilinx 4000E family configuration architecture using external PROM.

Technical Context

The XC4005E-2PC84I belongs to the Xilinx 4000E FPGA family, based on SRAM-based configurable logic blocks (CLBs), dedicated carry logic, and programmable interconnect. It supports in-system reconfiguration via JTAG boundary-scan (IEEE 1149.1) and serial mode configuration using a 18-pin PROM.

Configuration is performed through a master serial or slave serial interface, with support for multiple configuration modes including SelectMAP and JTAG. The device requires external configuration memory and does not include on-chip nonvolatile storage.

FAQ

What is the maximum operating frequency supported by XC4005E-2PC84I?

The XC4005E-2PC84I has a -2 speed grade with 12.5 ns maximum input-to-output delay (T_IO). Its practical maximum system clock frequency depends on design topology, but synchronous logic paths can achieve up to 60–70 MHz in well-constrained implementations. The XC4005E-2PC84I does not specify a guaranteed maximum clock frequency in its datasheet; timing analysis must be performed per design using Xilinx Foundation or Alliance software tools.

Does XC4005E-2PC84I include on-chip configuration memory?

No, the XC4005E-2PC84I is an SRAM-based FPGA and requires external configuration memory. It supports serial PROM (18-pin) or JTAG configuration at power-up. The XC4005E-2PC84I retains no configuration state after power loss and must be reloaded each time the system powers on or resets.

Is XC4005E-2PC84I RoHS compliant?

The XC4005E-2PC84I was introduced prior to RoHS Directive 2002/95/EC and is not RoHS compliant. It contains lead in the PLCC package solder finish and die attach. For RoHS-compliant alternatives, consider newer Xilinx Spartan or Artix families - the XC4005E-2PC84I remains available for legacy repair under exemption clauses.

Can XC4005E-2PC84I be programmed via JTAG in-system?

Yes, the XC4005E-2PC84I supports IEEE 1149.1 JTAG boundary-scan for in-system programming and debugging. Pins TDI, TDO, TCK, and TMS are assigned to PLCC pins 43, 44, 45, and 46 respectively. JTAG mode enables configuration without removing the XC4005E-2PC84I from the board, provided the JTAG chain is properly terminated and isolated during configuration.

What development tools support XC4005E-2PC84I design entry and place-and-route?

Xilinx Foundation Series and Alliance Series software versions up to 3.1i fully support the XC4005E-2PC84I. These tools provide schematic capture, VHDL/Verilog synthesis, timing-driven place-and-route, and bitstream generation. The XC4005E-2PC84I is not supported in modern Vivado or ISE 14.x+ toolchains due to architectural deprecation.
