Introduction

The Atmel® ATF15xx Complex Programmable Logic Device (CPLD) USB-based JTAG ISP Download

Cable [Atmel PN: ATDH1150USB] connects to a standard USB port on a host computer on one side

and to a JTAG header of a programming circuit board on the other side. It transfers the JTAG

instructions and data generated by the ATMISP software running on the host PC to the Atmel ATF15xx

series CPLDs on the programming circuit board. The ATMISP software can be downloaded from the

Atmel website at http://www.atmel.com/tools/ATMISP.aspx. With this In-System Programming (ISP)

download cable and the ATMISP software, design changes can easily be downloaded directly to the

ATF15xx JTAG devices, resulting in easy prototyping of designs.

The ATDH1150USB cables are made by two vendors and have identical circuit design. The cables

labeled with “ATDH1150USB-K” are built by Kanda (www.kanda.com) and can also be purchased

directly from Kanda. When purchasing this cable from Atmel or an Atmel distributor, the Atmel ordering

code is “ATDH1150USB”.

Features



Allows Users to Perform JTAG ISP of Atmel ATF15xx CPLDs





Supported by the ATMISP Software (Version 6.6, 6.7, and 7.x)



Interfaces with a Standard USB 2.0/3.0 Port on a PC



Supports 10-pin and 14-pin JTAG Interface Headers (JTAG-A and JTAG-X)

Supports

The ATDH1150USB ISP Download Cable supports all ATF15xx CPLDs with the JTAG feature enabled.

By default, the ATF15xx CPLDs are shipped with the non-volatile memory in the erased state, which

would enable the JTAG feature. Once the JTAG feature of an ATF15xx is disabled by programming it

with a JEDEC file that disables the JTAG feature, its memory contents can no longer be accessed via

the JTAG port. To re-enable the JTAG feature, the ATF15xx CPLD will need to be erased on a stand-

alone device programmer.
