Socket Adapter Board
The ATF15xx-DK3 CPLD Development/Programmer Socket Adapter Boards (ATF15xxDK3-XXXXX)
are circuit boards that interface with the ATF15xx-DK3 CPLD Development/Programmer Board. They
are used in conjunction with the ATF15xx-DK3 CPLD Development/Programmer Board to evaluate or
program ATF15xx ISP CPLD devices in different package types. There are four Socket Adapter
Boards available for the ATF15xx-DK3 covering the 44-TQFP, 44-PLCC, 84-PLCC, and 100-TQFP
package types in the ATF15xx family of CPLDs.
Each socket adapter board contains a socket for the ATF15xx device and has male headers on the
bottom side, labeled JP1 and JP2. The headers on the bottom side mate with the female headers on
the ATF15xx-DK3 board, labeled JP4 and JP3. The four 7-segment displays, push-button switches,
JTAG port signals, oscillator, V
CC
INT, V
CC
IO, and GND on the CPLD Development/Programmer Board
are connected to the ATF15xx device on the Socket Adapter Board through these two sets of
connectors.
On the top of the 44-TQFP socket adapter, there are four 10-pin connectors with the same dimensions
as the JTAG ISP connector. The pins of these four connectors are connected to the input and I/O pins
(except the four JTAG pins) of the target CPLD device. They can be used to connect to an oscilloscope
or logic analyzer to capture the activities of the input and I/O pins of the CPLD. They also can be used
to connect the input and I/O pins of the CPLD to other external boards or devices for system level
evaluation or testing.
Atmel ATF15xx ISP Download Cable
The ATF15xx USB ISP Download Cable connects the USB port of the PC to the 10-pin JTAG header
on the CPLD Development/Programmer Board or a custom circuit board. This ISP cable also acts as a
buffer to buffer the JTAG signals for the JTAG devices on the target circuit board. The status LED on
the ATF15xx USB ISP Download Cable indicates whether the communication between the PC and the
target JTAG devices and the JTAG operation are successful or not.
This ISP cable contains a standard B USB connector, which is connected to the USB port of a PC. The
10-pin female plug connects to the 10-pin male JTAG header on the ISP circuit board. The red color
stripe on the ribbon cable indicates the orientation of pin 1 of the female plug. The 10-pin male JTAG
header on the CPLD Development/Programmer Board is polarized to prevent users from inserting the
female plug in the wrong orientation.
The CPLD Development/Programmer kits includes the ATF15xx USB ISP Download Cable
(ATDH1150USB or ATDH1150USB-K); however, other supported ISP cables can also be used. The
ATDH1150VPC, ATDH1150USB, ByteBlasterMV, and ByteBlasterII cables can be used for the
ATF15xx/ASL (5V) and ATF15xxASV/ASVL (3.3V) devices, while the older ATDH1150PC and the
ByteBlaster cables can be used for the ATF15xxAS/ASL (5V) only.
Figure 10
illustrates the 10-pin female header pinout for the ATF15xx ISP Download Cable. The
10-pin male header pinout on the PC board (if used for ISP) must match this pinout.

Note:
The circuit board must supply V
CC
and GND to the CPLD ISP Cable through the 10-pin male header.
