Atmel-ISP Cable
Figure 4-4. Correct Orientation of Daughter Board on ISP Board
The Atmel-ISP cable connects between the parallel port of your PC and the 10-pin
JTAG header on your circuit board or the Atmel-ISP board. The power-on LED on the
25-pin male connector housing indicates that the cable is connected properly. Make
sure this LED is turned on before using the Atmel-ISP software.
The Atmel-ISP cable consists of a 25-pin male connector, which connects from the par-
allel port to a 10-pin female header connector. The female header connector connects
to the male 10-pin JTAG header on the ISP circuit board. The color stripe indicates the
orientation of Pin 1 on the header connector. Since the cable is not polarized, use the
color stripe as a guide to assure that the female header connector is properly oriented
when it is attached to either board. See Figure 4-5 for the correct orientation.
If you are attempting to program the ATF1500ASV low-voltage devices, you need to use
Rev. 4 or later of the Atmel-ISP cable. This and later revisions will support both the
ATF1500ASV and AS devices (3V and 5V, respectively). Earlier revisions of the cable
only support the ATF15xx (5V) devices.
The new revisions (Rev. 4 or later) of the cable have built-in circuitry that automatically
detects the supply voltage from your JTAG header and is able to adjust its programming
voltage levels accordingly to handle either AS or the ASV device programming.
