The ATF15XXDK3-SAJ84 is a CPLD development / programmer kit with 84 pin PLCC socket adapter board for DK3 board and an in-system programming (ISP) programmer for the ATF15xx family of industry standard pin compatible complex programmable logic devices (CPLDs) with logic doubling features. This kit provides designers a very quick and easy way to develop prototypes and evaluate new designs with an ATF15xx ISP CPLD. The ATF15xx family of ISP CPLDs includes the ATF15xxAS, ATF15xxASL, ATF15xxASV, ATF15xxASVL, and ATF15xxBE CPLDs. With the availability of the different socket adapter boards to support all the package types offered in the ATF15xx family of ISP CPLDs, this CPLD development / programmer board can be used as an ISP programmer to program the ATF15xx ISP CPLDs in all the available package types through the industry standard JTAG interface (IEEE 1149.1).
