PLCC-44 to DIP-40 Programming Adapter — Microchip PIC17C42 — Clamshell Socket

Overview

The PA17C42-PDZ is a device-specific programming adapter designed for Microchip PIC17C42, PIC17C43, and PIC17C44 devices. This adapter supports PLCC packages conforming to JEDEC MO-047-AC and converts the interface to a 40-pin DIP footprint for programming and test applications. It features a clamshell socket for secure device retention and consistent electrical contact during repeated programming cycles.

Interface

This adapter converts a 44-pin PLCC device to a 40-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.
