Description and Introduction

CMOS single-chip 8-bit microcontrollers The **PCB80C31BH-316WP** is an advanced microcontroller unit (MCU) from Philips, designed for embedded control applications requiring high performance and reliability. As part of the 80C51 family, this component features an 8-bit architecture with enhanced processing capabilities, making it suitable for industrial automation, automotive systems, and consumer electronics.  

Key specifications of the PCB80C31BH-316WP include a **16 KB OTP (One-Time Programmable) ROM**, **256 bytes of RAM**, and a **16-bit timer/counter** for precise timing operations. Its **low-power CMOS technology** ensures efficient energy consumption, while the **extended temperature range** (-40°C to +85°C) allows operation in harsh environments. The microcontroller supports **UART communication**, enabling seamless serial data transfer, and features **32 I/O lines** for versatile interfacing with peripherals.  

Packaged in a **PLCC-44** form factor, the PCB80C31BH-316WP offers compact integration for space-constrained designs. Its robust architecture, combined with Philips' legacy in semiconductor innovation, makes it a dependable choice for developers seeking a balance of performance and durability.  

Engineers and designers favor this MCU for its backward compatibility with the 80C51 instruction set, simplifying migration from earlier designs while leveraging modern enhancements. Whether used in motor control, instrumentation, or smart devices, the PCB80C31BH-316WP delivers consistent performance in demanding applications.

Application Scenarios & Design Considerations

CMOS single-chip 8-bit microcontrollers

Alternative Part Number

  • AT89C51-24PC --: Pin-compatible 8051 microcontroller with 4KB flash, direct functional replacement for the 80C31 in most embedded designs.
  • P89C51RB2HFA --: NXP 8051-family MCU with compatible core and pinout, suitable drop-in substitute for legacy 80C31 applications.
  • W78E516B40PL --: 8051-compatible microcontroller with similar architecture and package options, widely used as a replacement for older 80C31 parts.
  • P80C31BH --: Intel 80C31 is the original CMOS 8051-family microcontroller that Philips second-sourced; same 8031 core, 128 bytes RAM, 4K external program memory, DIP-40 pinout, so it is a direct functional drop-in.
  • AT89C51 --: Atmel AT89C51 is a widely available 8051-compatible MCU with 4K flash, 128 bytes RAM and DIP-40 pinout; it can replace the ROMless 80C31 in most designs and is easier to source.
  • W78E51B --: Nuvoton W78E51B is an 8051-compatible microcontroller with 4K flash and DIP-40 package, offering a modern, in-production alternative to the obsolete Philips 80C31.
