AMD XC4005XL-3PQ100I

Overview

XC4005XL-3PQ100I from Xilinx is a Spartan-XL family FPGA with 5,000 usable gates, 100-pin PQFP package, -3 speed grade (3.5 ns CLB delay), and industrial temperature range (-40°C to +100°C); used in digital logic control, interface bridging, and embedded system acceleration.

For engineers reviewing the XC4005XL-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 and routing constraints, and Spartan-XL configuration mode support (JTAG, master serial, slave parallel).

Technical Context

The XC4005XL-3PQ100I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM (up to 128 bits per CLB), and dedicated carry logic for arithmetic functions. It supports IEEE 1149.1 JTAG boundary-scan testing and in-system configuration via serial PROM or microprocessor interface.

Configuration is performed through dedicated pins (INIT, PROGRAM, DONE) and supports multiple modes including Master Serial (using on-chip oscillator), Slave Parallel, and JTAG. The device uses SRAM-based configuration memory and requires external configuration memory or controller at power-up.

The Spartan-XL family was engineered for cost-sensitive, high-volume industrial and communications applications requiring reliable non-volatile configuration alternatives and robust I/O flexibility.

FAQ

What is the configuration method supported by XC4005XL-3PQ100I?

The XC4005XL-3PQ100I supports three configuration modes: Master Serial (using internal oscillator and external PROM), Slave Parallel (via microprocessor bus), and IEEE 1149.1 JTAG. Each mode uses dedicated pins (PROGRAM, INIT, DONE, TCK/TMS/TDI/TDO) and requires specific external circuitry - no single method is default; selection depends on system architecture and production test requirements. XC4005XL-3PQ100I does not support passive serial or BPI modes.

Does XC4005XL-3PQ100I support hot-swap or live insertion?

No, XC4005XL-3PQ100I does not support hot-swap operation. Its I/O pins lack hot-swap protection circuitry such as programmable clamp diodes or slew-rate limiting in powered-down states. Applying signal or power to XC4005XL-3PQ100I while VCCINT or VCCO is unpowered may cause latch-up or permanent damage. System-level hot-swap capability must be implemented externally using buffer ICs or power sequencing controllers.

What is the maximum clock frequency achievable with XC4005XL-3PQ100I?

The XC4005XL-3PQ100I's -3 speed grade specifies a 3.5 ns CLB propagation delay, enabling synchronous designs with maximum clock frequencies up to ~125 MHz for register-to-register paths under typical conditions. Actual performance depends on logic depth, routing congestion, and I/O timing closure. XC4005XL-3PQ100I does not include dedicated PLLs or DLLs, so clock multiplication or skew management must be implemented in logic or with external components.

Can XC4005XL-3PQ100I operate with mixed I/O voltages?

Yes, XC4005XL-3PQ100I supports mixed I/O voltages: VCCO can be set independently per I/O bank to either 3.3 V or 5.0 V, allowing simultaneous interfacing with LVTTL (3.3 V) and TTL (5.0 V) devices. However, all pins within a given bank must share the same VCCO voltage. XC4005XL-3PQ100I does not support 1.8 V or 2.5 V I/O standards - those require later Spartan families.

Is XC4005XL-3PQ100I still in production or obsolete?

XC4005XL-3PQ100I is discontinued by AMD/Xilinx and no longer in active production. However, Aetrix Electronics maintains verified legacy inventory with full traceability and extended lifecycle support. Datasheets, configuration tools, and application notes remain publicly archived. XC4005XL-3PQ100I is supplied exclusively as new-old-stock (NOS) with full authenticity validation and burn-in testing where applicable.
