AMD XC4005E-3PQ100I

Overview

XC4005E-3PQ100I from Xilinx is a Field-Programmable Gate Array (FPGA) with 5,000 usable gates, 100-pin PQFP package, -3 speed grade (12.5 ns CLB propagation delay), and industrial temperature range (-40°C to +100°C). It implements synchronous logic in digital signal processing, motor control interface, and embedded system glue logic.

For engineers reviewing the XC4005E-3PQ100I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (84 user I/Os), speed grade timing, PQFP thermal profile, and legacy 5V CMOS compatibility.

Technical Context

The XC4005E-3PQ100I 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 SRAM-based configuration via serial or parallel mode and includes dedicated carry logic for arithmetic functions.

It operates at 5V supply voltage, features tri-stateable I/Os with programmable slew rate control, and supports IEEE 1149.1 JTAG boundary-scan testing. Configuration data is volatile and requires external PROM or processor loading at power-up.

FAQ

What is the maximum operating frequency supported by the XC4005E-3PQ100I?

The XC4005E-3PQ100I has a -3 speed grade specifying 12.5 ns CLB propagation delay, enabling reliable operation up to approximately 80 MHz for register-to-register paths in typical designs. Actual system frequency depends on routing, logic depth, and I/O timing constraints. The XC4005E-3PQ100I does not guarantee performance beyond its characterized speed grade limits.

Does the XC4005E-3PQ100I support in-system programming?

The XC4005E-3PQ100I supports in-system programming via JTAG (IEEE 1149.1) boundary-scan interface, allowing configuration bitstream updates without removing the device from the board. However, it requires external configuration memory or host processor control for SRAM reload after power cycle. The XC4005E-3PQ100I itself retains no non-volatile configuration storage.

Can the XC4005E-3PQ100I operate at 3.3V?

No, the XC4005E-3PQ100I is specified only for 5.0 V ± 5% supply operation and is not compatible with 3.3V I/O standards. Using 3.3V may cause functional failure or damage. Level-shifting circuitry is required when interfacing with 3.3V systems. The XC4005E-3PQ100I must be powered from a regulated 5V rail.

How many configuration modes does the XC4005E-3PQ100I support?

The XC4005E-3PQ100I supports three primary configuration modes selected by M0–M2 pins: Master Serial (internal oscillator drives serial PROM), Slave Serial (external controller clocks data), and SelectMAP (8-bit parallel interface). All modes use the same XC4005E-3PQ100I pin assignments and require proper INIT and DONE signal handling.

Is the XC4005E-3PQ100I RoHS compliant?

The XC4005E-3PQ100I was manufactured prior to RoHS Directive enforcement and contains leaded solder in its PQFP package. It is not RoHS compliant. For new designs requiring compliance, consider migration paths to newer Xilinx families or consult Aetrix Electronics for legacy-compliant sourcing options. The XC4005E-3PQ100I remains available for repair and obsolescence management.
