Cheap & simple evaluation boards for Microchip ATF15xx CPLDs
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.
