PLCC-44 to DIP-28 Programming Adapter — Microchip PIC17C42 — Clamshell Socket

Overview

The PA17C42-44Z-CP1128 is a device-specific PLCC to DIP programming adapter designed for Microchip PIC17C42, PIC17C43, and PIC17C44 devices, including use with BP Micro programming environments. This adapter supports PLCC packages conforming to JEDEC MO-047-AC and converts the interface to a 28-pin DIP footprint for programming and test applications. It features a Yamaichi clamshell socket for secure device retention and reliable contact in repeated programming cycles.

Interface

This adapter converts a 44-pin PLCC device to a 28-pin DIP footprint with a .600" row spacing. The top interface follows JEDEC MO-047-AC dimensions with a .050" pitch, .653" x .653" body size, and .690" x .690" shoulder size. Wiring is device specific, so pin mapping should be confirmed against the datasheet.
