ATF1502-EVB

ATF1502-EVB is a simple and low-cost evaluation board for the Microchip ATF1502AS CPLD. It may also be used with ATF1504AS in the TQFP-44 package. It breaks out every I/O pin on a DIP-style package, exposes JTAG on a 6-pin connector, and optionally (with a solder jumper) allows two LEDs to be connected to pins 22 and 23 of the CPLD.

PCBWay has sponsored a prototype batch of these boards, and I'm very happy with how they turned out. (Thanks!) See this Twitter thread for details.

ATF1502AS-EVB-PLCC44-COBBLER

The ATF1502AS-EVB-PLCC44-COBBLER board features the same ATF1502AS CPLD, but the variant that comes in a PLCC44 package. The style of the board is a 'cobbler', designed to be easily inserted into a breadboard. It also features a secondary jtag port designed to be compatible with Olimex ARM-USB-TINY adapters.

ATF1502-EVB-PLCC

The ATF1502-EVB-PLCC board, is a variant for the PLCC-44 package, socketed. It routes the same signals to the headers in the same order and includes the same pin numbers on the silkscreen. These numbers reflect the TQFP-44 pin numbers, but everything is connected correctly to the PLCC-44 package, which has the same 44 signals but in a slightly different order.
