Adapter for specific MCU devices in the QFP-44 package to be used with the GALEP programmer (40 pin DIL). It can also be used with most other programmers.

For the different devices in the DIL-40 package an appropriate pin configuration at the GALEP socket will be selected. The same pin configuration is used for the QFP-44 devices. Because there are different pinouts for the QFP-44 devices, the plug position of the upper board at the lower bord must be correctly selected:

Pos. 1: e.g. P87C591 (Philips)
Pos. 2: e.g. T89C51AC2, T89C51CC01 (Atmel)
