PA705C8-DP-PP – DIP Socket to PLCC Emulator Adapter (Motorola MC68HC705C8)

Overview

PA705C8-DP-PP is a PLCC emulator adapter designed for the Motorola MC68HC705C8 microcontroller. As a result, engineers can evaluate and emulate DIP-packaged HC705 devices in systems that require a PLCC emulator interface.

On the top side, the adapter provides a DIP socket suitable for MC68HC705C8 devices and emulator cable connections. Therefore, it supports both direct device insertion and lab emulation workflows.

On the bottom side, the adapter presents a PLCC plug interface. Consequently, it inserts directly into PLCC emulator sockets without additional interposers or cabling.

This adapter uses device-specific wiring rather than 1:1 pin mapping. Instead, it aligns HC705 port, reset, interrupt, oscillator, and programming signals between DIP and PLCC formats. The Adapter Wiring table documents the exact connections.
