Description and Introduction

CMOS single-chip 8-bit microcontrollers **Introduction to the PCB80C31BH-3-16WP Microcontroller**  

The **PCB80C31BH-3-16WP** is an 8-bit microcontroller from Philips (now NXP Semiconductors), designed for embedded control applications. Based on the 80C51 architecture, it combines high performance with low power consumption, making it suitable for industrial, automotive, and consumer electronics.  

This microcontroller operates at a clock speed of **16 MHz** and features **128 bytes of RAM** and **4 KB of ROM**, providing sufficient memory for small to medium-scale applications. Its **16-pin windowed ceramic package (DIP)** allows for UV erasure, facilitating reprogramming during development.  

Key features include **two 16-bit timers/counters**, **32 I/O lines**, and a **full-duplex UART** for serial communication. The **PCB80C31BH-3-16WP** also supports external memory expansion, enhancing flexibility for complex designs. With its robust instruction set and efficient power management, it remains a reliable choice for legacy systems and new designs requiring backward compatibility.  

Engineers value this component for its durability, ease of integration, and proven performance in demanding environments. Whether used in automation, instrumentation, or communication systems, the **PCB80C31BH-3-16WP** delivers consistent functionality and long-term reliability.

Application Scenarios & Design Considerations

CMOS single-chip 8-bit microcontrollers

Alternative Part Number

  • P80C31BH --: Original 8051-family microcontroller in the same 80C31 configuration; Intel is the originator of the MCS-51 architecture and this part is functionally equivalent to the Philips device.
  • AT89C51-16PC --: Widely available 8051-compatible microcontroller with 4KB flash, 16 MHz operation, and a similar 40-pin DIP package; a common drop-in replacement for legacy 80C31 designs.
  • DS89C430-MNG --: High-speed 8051-compatible microcontroller with pin-compatible 40-pin package and 16 MHz-class operation, suitable as a modern replacement for the Philips 80C31.
  • AT89C51-24PC --: 8051-compatible microcontroller in 40-pin DIP with 4KB flash, widely available and functionally interchangeable for most 80C31 applications.
  • DS89C430-MNL --: High-speed 8051-compatible microcontroller in 40-pin DIP, offers higher performance and can replace the 80C31 in existing sockets.
