Product Description

Xilinx Parallel Cable III – JTAG Programming/Debug Cable

The Xilinx Parallel Cable III is a legacy JTAG programming and debugging cable used to configure and test Xilinx FPGAs, CPLDs, and PROMs from a desktop computer’s parallel (printer) port. It was a standard tool for engineers and technicians working with older Xilinx-based designs.

Key Features & Specifications:

• Interface: DB25 male to 14-pin JTAG header (often with an adapter)

• Target Devices: Xilinx FPGAs (Spartan, Virtex families), CPLDs, and platform flash PROMs

• Host Connection: PC Parallel Port (IEEE 1284)

• Compatibility: Works with legacy Xilinx ISE software tools (e.g., iMPACT)

• Function: In-system programming, configuration, and boundary-scan testing

Applications:

• Programming and debugging legacy Xilinx FPGA/CPLD designs in existing equipment

• Educational use for historical digital design courses

• Maintaining or repairing older industrial, military, or telecom hardware with Xilinx chips
