ATF15xx CPLD JTAG ISP Download Cable
USER GUIDE
Introduction
The Atmel® ATF15xx Complex Programmable Logic Device (CPLD) LPT-based JTAG ISP Download
Cable [Atmel PN: ATDH1150VPC] connects to a standard parallel port of a PC on one side and to a
10-pin 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 a PC to the Atmel ATF15xx series CPLDs on
the target 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,
design changes can easily be downloaded directly to the ATF15xx JTAG devices, resulting in easy
prototyping of designs.

The ISP circuit board must supply VCC and GND to the ATDH1150VPC ISP Download Cable
through the 10-pin JTAG male header. A regulated VCC voltage between 1.7V to 5.5V is
recommended, and it should be the same VCC supply used by the JTAG devices.

The Power LED on the 10-pin male connector can be used to show the cable is connected properly.
The user must make sure this LED is turned on before using the ATMISP software to program the
JTAG devices. The color stripe on ATDH1150VPC ISP Download Cable indicates the orientation of Pin
1 of the JTAG connector. The color stripe or the polarized connector can be used as a guide to assure
that the female connector is properly oriented when it is attached to the board. This cable has built-in
circuitry to adjust its programming voltage level according to the VCC applied to the cable via Pin 4 of
the 10-pin JTAG connector. The following figure illustrates the correct orientation of ATDH1150VPC
ISP Download Cable on the programming circuit side.

Frequently Asked Questions
For a multiple device JTAG hardware chain, which device is considered the first
device (Device #1) when setting up the Atmel CPLD ISP (ATMISP) software?
The device with its TDI pin connected to the TDI pin of the 10-pin JTAG header is the first
device (Device #1) of a JTAG chain. The device with its TDO pin connected to the TDO pin
of the 10-pin JTAG header is the last device of the chain.
For devices with different VCCINT and VCCIO supplies, which VCC (VCCIO or VCCINT)
should be used to supply the ATDH1150VPC ISP Download Cable's VCC?
VCCIO should be used to supply the VCC of the ATDH1150VPC ISP Download Cable.
Can a JEDEC file with the JTAG port feature disabled be programmed into the
ATF15xx through JTAG ISP?
Since all ATF15xx devices are shipped in a blank (erased) state, the JTAG port is enabled by
default. Therefore, they can be programmed with a JEDEC file with the JTAG port feature
disabled ONLY ONCE via JTAG ISP. However, this is not recommended since the pins used
for the JTAG port can become outputs immediately after programming is completed and they
can content with the output drivers in the ATDH1150VPC ISP Download Cable. Furthermore,
please note that once the JTAG port is disabled, the device can no longer be accessed
through the JTAG port. To re-enable the JTAG port, you must erase the device or reprogram the device with a JEDEC file with the JTAG port feature enabled using a standalone 3rd-party device programmer from vendors such as BPM Microsystems, Data I/O, HiLo Systems,. etc.
In the Port Setting dialog box of the ATMISP v6.x software window, what LPT port
addresses are associated to the LPT1, LPT2 and LPT3 settings?
LPT1 - 378 (hex), LPT2 - 278 (hex), LPT3 - 3BC (hex).
The LPT port address of my PC is 1AFF (hex). How do I specify this address in the
ATMISP software?
From the main ATMISP window, select Other in the Port Setting dialog box. In the Port
Setting window, enter 1AFF and click OK. Any 3 or 4-digit hex values can be entered into this
window.
