Overview of Xilinx JTAG Programming Cables and Reference Schematics for Legacy
R Overview of Xilinx JTAG Programming Cables and Reference Schematics for Legacy XTP029 (v1.0) March 28, 2008 Parallel Cable III (PC3) Summary This technical publication provides an overview of Xilinx JTAG Cables and a reference schematic for the legacy Xilinx Parallel Cable III product (PC3) for educational use. Description Xilinx offers the Hi-Speed Platform Cable USB (PCUSB) and the Parallel Cable IV (PC4) cables. The PC4 cable supports both the IEEE 1284 parallel port interface and IEEE STD 1149.1 (JTAG) standards for in-system programming or embedded debug. These cables are more thoroughly described in the “Overview of Xilinx JTAG Solutions.” For reference purposes, the PC3 product schematic is also provided in this document. Note: The PC3 cable product has been discontinued and replaced by PCUSB and PC4. Both the PCUSB and PC4 cables have expanded capabilities, superior download performance, and robust immunity to system interface sensitivities when compared to the legacy PC3 cable. The PC3 product was first introduced in 1998 and then discontinued in 2002. Software support for PC3 was removed starting in March 2008 with the 10.1 release of Xilinx iMPACT software. Versions of iMPACT software after 10.1 release do not support the PC3 cable. See “Notice of Disclaimer” regarding warranty and support of the PC3 schematic information. Overview of Xilinx recommends the Platform Cable USB (PCUSB) or Parallel Cable IV (PC4) for new Xilinx JTAG designs. The PCUSB and PC4 offer reliable operation, higher speed download, voltage support down to 1.5V, keyed ribbon cable connector for error-free insertion, and improved ground/signal Solutions integrity. -

Printers and other devices attached to parallel ports should be capable of high- speed, bidirectional data transfers. The design criteria for parallel devices follow those for parallel ports described in the “Serial, Parallel, and Wireless Support” chapter. The PC 97 requirements for printers and parallel ports seek to ensure the following: • Ensure maximum speed for transfer of parallel data between the system and the peripheral. • Ensure a true Plug and Play experience for users. Basic Printer Features This section summarizes the basic hardware requirements for printers for PC 97. Basic Features for IEEE 1394 Printers This section defines requirements for printers that use IEEE 1394. 1. Compliance with PC 97 requirements for IEEE 1394 Required This bus is recommended in PC 97 for support of fast, high-density data transfer. For information about implementing IEEE 1394 for PC 97, see the “IEEE 1394” chapter in Part 3 of this guide.
