AMD XC4005XL-3PQ160I

Overview

XC4005XL-3PQ160I from Xilinx is a Spartan-XL family FPGA with 5,000 usable gates, 160-pin PQFP package, -3 speed grade (10 ns CLB delay), and industrial temperature range (-40°C to +85°C); used in digital logic control, interface bridging, and embedded system acceleration.

For engineers reviewing the XC4005XL-3PQ160I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (120 user I/Os), configuration mode (serial or parallel PROM), internal RAM (16 kbits), and IEEE 1149.1 JTAG boundary-scan support.

Technical Context

The XC4005XL-3PQ160I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM per CLB, and dedicated carry logic for arithmetic functions. It supports in-system reconfiguration via JTAG and accepts configuration data from external serial PROM or parallel master mode.

It features programmable I/O standards including LVTTL, TTL, and CMOS-compatible levels, with individual output slew-rate control and pull-up resistors. Configuration is volatile and requires external PROM at power-up.

Key Specifications

Pinout & Package

XC4005XL-3PQ160I is housed in a 160-pin Plastic Quad Flat Pack (PQFP) with 40 pins per side, 0.65 mm pitch, and exposed thermal pad not present. Pin functions include dedicated configuration inputs (INIT, PROGRAM, CCLK), JTAG TAP controller signals (TCK, TMS, TDI, TDO), and dual-purpose I/O banks supporting multiple voltage standards.

FAQ

What is the configuration method supported by XC4005XL-3PQ160I?

The XC4005XL-3PQ160I supports multiple configuration methods: Master Serial (using on-chip oscillator), Slave Serial, Slave Parallel, and JTAG boundary-scan. It requires external non-volatile PROM for automatic configuration at power-up due to its volatile SRAM-based logic cells. The XC4005XL-3PQ160I does not include on-chip flash memory.

Does XC4005XL-3PQ160I support hot-swap or live-insertion?

No, the XC4005XL-3PQ160I is not rated for hot-swap operation. Its I/O structures lack bus-hold or hot-swap protection circuitry, and configuration integrity cannot be guaranteed during partial power sequencing. Safe operation requires full power stabilization before configuration begins. This applies specifically to the XC4005XL-3PQ160I in its standard industrial-grade PQFP package.

What is the maximum operating frequency achievable with XC4005XL-3PQ160I?

The XC4005XL-3PQ160I has a -3 speed grade specifying 10 ns CLB propagation delay, enabling synchronous logic paths up to approximately 100 MHz under typical conditions. Actual maximum frequency depends on design topology, routing congestion, and I/O timing constraints. The XC4005XL-3PQ160I does not guarantee 100 MHz across all paths without timing closure verification.

Can XC4005XL-3PQ160I replace older XC4000 series devices in existing PCBs?

The XC4005XL-3PQ160I shares the same 160-pin PQFP package and pinout as earlier XC4005 devices, enabling direct PCB replacement where configuration PROM and power delivery match. However, differences in INIT/PROGRAM timing and voltage tolerance require validation. The XC4005XL-3PQ160I is not a drop-in replacement for XC4005-PC84 or other package variants.

Is JTAG debugging supported on XC4005XL-3PQ160I?

Yes, the XC4005XL-3PQ160I fully supports IEEE 1149.1 JTAG boundary-scan for device programming, interconnect testing, and in-circuit debugging. TCK, TMS, TDI, and TDO pins are dedicated and electrically compliant. JTAG functionality is active immediately after power-up, independent of configuration status - a key capability of the XC4005XL-3PQ160I.
