AMD XC4005E-4PQ160I

Overview

XC4005E-4PQ160I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 160-pin Plastic Quad Flat Package (PQFP), -4 speed grade (15 ns CLB propagation delay), and industrial temperature range (-40°C to +100°C). It implements synchronous logic in digital signal processing, peripheral interface bridging, and real-time control subsystems.

For engineers reviewing the XC4005E-4PQ160I datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O pin count, speed grade timing, industrial temperature rating, and legacy 5V-compatible configuration interface support.

Technical Context

The XC4005E-4PQ160I belongs to the Xilinx XC4000E FPGA family, built on 0.5 µm CMOS technology with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports in-system programmability via JTAG boundary-scan and serial PROM-based configuration.

It features 192 CLBs, 160 user I/O pins, dedicated carry logic for arithmetic functions, and global clock routing with low skew. Configuration is performed through a 5V-tolerant 4-pin serial mode using an external PROM or master processor.

FAQ

What is the maximum operating frequency supported by the XC4005E-4PQ160I?

The XC4005E-4PQ160I has a -4 speed grade specifying 15 ns CLB propagation delay, enabling reliable operation up to approximately 66 MHz in register-to-register paths under typical conditions. Actual system clock frequency depends on design topology, routing, and I/O timing constraints. The XC4005E-4PQ160I does not include internal PLLs, so clock multiplication must be implemented externally or via logic-based frequency synthesis.

Does the XC4005E-4PQ160I support in-system programming (ISP)?

Yes, the XC4005E-4PQ160I supports in-system programming via its IEEE 1149.1 JTAG TAP controller, allowing configuration bitstream loading and readback without removing the device from the PCB. This capability is integral to the XC4005E-4PQ160I architecture and requires only standard JTAG boundary-scan infrastructure.

Is the XC4005E-4PQ160I pin-compatible with earlier XC4000 series devices?

The XC4005E-4PQ160I shares the same 160-pin PQFP footprint and I/O assignment as the XC4005-4PQ160C and XC4005-4PQ160I, enabling direct PCB replacement in most cases. However, differences in configuration mode defaults and power-up behavior require verification of INIT and PROGRAM pin handling in existing schematics before substitution.

What configuration memory size is required for the XC4005E-4PQ160I?

The XC4005E-4PQ160I requires a serial PROM with at least 192 Kbits of configuration memory to store its full bitstream. Commonly used devices include Xilinx XC18V02 (2 Mbit) or compatible third-party 2-Mbit SPI PROMs. The XC4005E-4PQ160I loads configuration data serially on power-up or after PROGRAM assertion, with INIT confirming successful load completion.

Can the XC4005E-4PQ160I operate with 3.3V I/O signaling?

No, the XC4005E-4PQ160I is a 5V-only device with 5V-tolerant I/Os but no internal 3.3V or mixed-voltage I/O support. Its IOBs are designed for 5V LVTTL/LVCMOS signaling levels and require V_CC = 5.0 V ± 5%. Interfacing with 3.3V systems necessitates level-shifting circuitry or external translators, as the XC4005E-4PQ160I itself cannot drive or accept 3.3V logic levels safely.
