        ATF1502-EVB

===========

*ATF1502-EVB* is a simple and low-cost evaluation board for the [Microchip ATF1502AS](https://www.microchip.com/wwwproducts/en/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](https://www.pcbway.com/) has sponsored a prototype batch of these boards, and I'm very happy with how they turned out.  (Thanks!) See [this Twitter thread](https://twitter.com/whitequark/status/1238286231433330688) 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.

ATF1508AS-EVB-PLCC84

====================

The *ATF1508AS-EVB-PLCC84* board features the bigger ATF1508AS CPLD, this board supports the variant that comes in a PLCC84 package.

It 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.
