PA40-44-33-DP-PP – 40-Pin DIP Socket to 44-Pin PLCC Emulator Adapter (Atmel AT90(L)S4434 / 8535)

Overview

PA40-44-33-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 lab 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 1:1 pin mapping. Instead, it aligns the DIP device signals to the PLCC footprint and applies defined skips and shorts. The Adapter Wiring tables list the exact connections.

Adapter Wiring

The following chart shows the connections from the DIP device to the adapter’s PLCC plug. The wiring is shown in two parallel tables for readability.

The left table lists Device pins and signals mapped to corresponding PLCC Plug pins. In parallel, the right table lists additional PLCC Plug pins mapped back to their associated Device pins and signals.

Skip short notation: 1, 12, 23, 34 (1–2), (23–24) PLCC rotated CCW (+11).

Package Includes

• One PA40-44-33-DP-PP DIP-40 socket to PLCC-44 emulator adapter

Compatibility Note

This adapter does not use 1:1 wiring. Instead, it applies AVR-specific pin mapping and defined skip/short behavior as listed in the Adapter Wiring section. Therefore, verify target and emulator requirements before use.

Why Choose This Adapter

PA40-44-33-DP-PP provides documented wiring for AVR emulation in PLCC-based systems. Moreover, it reduces setup time during firmware development.

Because it uses controlled routing, it minimizes pinout mistakes. As a result, engineers can focus on test results instead of connection debugging.

Streamline Your Workflow

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