PA40-44-30-DP-PP – 40-Pin DIP Socket to 44-Pin PLCC Emulator Adapter (Atmel AT90(L)S4434 / 8535)

Overview

PA40-44-30-DP-PP is a PLCC emulator adapter designed for Atmel AT90(L)S4434 and AT90(L)S8535 microcontrollers. As a result, engineers can evaluate 40-pin DIP AVR devices using systems that require a 44-pin PLCC emulator interface.

On the top side, the adapter provides a 40-pin DIP socket on 0.100″ (2.54 mm) pitch. Therefore, it accepts DIP-packaged AVR devices used in firmware development and validation workflows.

On the bottom side, the adapter presents a 44-pin PLCC plug. Consequently, it inserts directly into PLCC emulator sockets without additional cabling.

This adapter uses device-specific wiring rather than full 1:1 pin mapping. Instead, it aligns the AVR DIP pinout to the PLCC footprint while implementing defined skips and shorts required by the target devices.

Package Includes

• One PA40-44-30-DP-PP DIP-40 socket to PLCC-44 emulator adapter

Compatibility Note

This adapter does not use 1:1 wiring. Instead, it applies Atmel AVR-specific pin mapping with defined skips and shorts as listed above. Therefore, verify target and emulator requirements before use.

Why Choose This Adapter

PA40-44-30-DP-PP provides a documented and repeatable solution for AVR emulation in PLCC-based systems. Moreover, it reduces setup complexity during development.

Because the adapter uses controlled routing, it minimizes wiring errors. As a result, engineers can focus on firmware rather than hardware setup.

Streamline Your Workflow

Use this adapter to integrate DIP-based AVR devices into PLCC emulator environments efficiently. Consequently, development and validation cycles move faster.
