PA51-DP-PP – 40-Pin DIP to PLCC Emulator Adapter (8051 Family)

Overview

PA51-DP-PP is a 40-pin DIP to PLCC emulator adapter designed for Intel 8051-family microcontrollers and compatible devices.

It interfaces 40-pin DIP 8051 devices to PLCC-based emulator systems used in development and validation environments.

The top interface is a 40-pin DIP socket on 0.100″ (2.54 mm) pitch.
The bottom interface is a PLCC emulator plug designed to mate with standard PLCC emulator sockets.

This adapter does not use 1:1 wiring. Signal routing follows the 8051 DIP-to-PLCC pin relationship as defined in the wiring table above.

Technical Specifications

• Part Number: PA51-DP-PP
• Top Interface: DIP-40 socket, 0.100″ (2.54 mm) pitch
• Bottom Interface: PLCC emulator plug
• Wiring: 8051-family specific pin mapping
• Pitch: DIP side 0.100″ (2.54 mm); PLCC side 0.050″ (1.27 mm)
• Applications: Emulation, firmware development, lab validation

Compatibility

Verify that the target device is a 40-pin DIP 8051-family microcontroller and that the emulator socket supports the required PLCC configuration. This adapter implements device-specific routing and is not 1:1 mapped.
