PA552-68Z
68 PLCC to 40 DIP Programming Adapter for 87C550/552/554

This adapter features a lidded Zero-Insertion-Force socket for programming 68-pin PLCC or CLCC packaged Philips and Dallas microcontrollers in a DIP-socketed programmer. The 40 pin DIP plug span is 0.6”.

The adapter has a three-piece modular construction, allowing you to replace the individual sub-assemblies when they wear out.

Supported devices include the following:

Philips 87C552, 87C554
Dallas 87C550
This adapter emulates the 40-pin DIP footprint of the 87C51FA (8K) and 87C52FB (16K).
