AMD XC4005E-4PQ208I

Overview

XC4005E-4PQ208I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 208-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 digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4005E-4PQ208I datasheet, pinout, applications, or equivalent options, key selection factors include gate count, I/O count (168 user I/Os), speed grade timing, PQ208 package thermal and routing constraints, and Spartan-compatible configuration interface support.

Technical Context

The XC4005E-4PQ208I belongs to the Xilinx XC4000E FPGA family, built on 0.5 µm CMOS technology. It contains 272 Configurable Logic Blocks (CLBs), each with two 3-input LUTs and flip-flops, and supports SRAM-based in-system reconfiguration via JTAG or serial PROM.

It features dedicated carry logic for high-speed arithmetic, global clock routing with low skew, and configurable I/O cells supporting TTL, CMOS, and LVTTL signaling standards. Configuration is performed through the SelectMAP or slave serial interface using external memory or host processor.

FAQ

What is the maximum operating frequency supported by XC4005E-4PQ208I?

The XC4005E-4PQ208I has a -4 speed grade specifying 15 ns CLB propagation delay. Its practical maximum system clock frequency depends on design topology, but synchronous logic paths can achieve up to 66 MHz under typical routing and loading conditions. The device does not include an on-chip PLL; clock management relies on external sources or global routing resources. XC4005E-4PQ208I timing must be verified per design using Xilinx Foundation or Alliance software tools.

Does XC4005E-4PQ208I support in-system programming (ISP)?

Yes, XC4005E-4PQ208I supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). This enables configuration bitstream loading, boundary-scan testing, and debug access without removing the device from the board. XC4005E-4PQ208I also supports master serial and SelectMAP modes using external PROM or host processor-no dedicated ISP controller IC is required.

What configuration memory technology does XC4005E-4PQ208I use?

XC4005E-4PQ208I uses volatile SRAM-based configuration memory. It requires external nonvolatile storage (e.g., serial PROM or flash) to reload the bitstream at power-up. The device includes dedicated PROGRAM and INIT pins to manage configuration sequence and status reporting. XC4005E-4PQ208I retains no configuration state after power loss and must be reloaded before functional operation.

Can XC4005E-4PQ208I operate in automotive environments?

No, XC4005E-4PQ208I is rated for industrial temperature range (-40°C to +100°C), not automotive AEC-Q100 qualification. While its operating range overlaps with some automotive under-hood zones, it lacks automotive-specific reliability testing, failure-in-time (FIT) data, and qualified supply chain controls. XC4005E-4PQ208I is intended for industrial control, test equipment, and communications infrastructure-not safety-critical automotive ECUs.

Is XC4005E-4PQ208I pin-compatible with other XC4000E family members in PQ208 package?

XC4005E-4PQ208I shares the same PQ208 pinout with other XC4000E devices in that package (e.g., XC4003E, XC4010E), including identical power, ground, I/O, clock, and configuration pin locations. However, I/O bank voltage assignments and internal CLB count differ-pin compatibility does not guarantee functional or timing equivalence. XC4005E-4PQ208I designs require full re-synthesis and place-and-route when migrating to larger or smaller variants.
