Description and Introduction

CMOS single-chip 8-bit microcontrollers The **PCB80C31BH-4-24P** is a high-performance microcontroller from the MCS-51 family, designed for embedded control applications. Built with a robust 8-bit architecture, this component operates at a clock speed of 24 MHz, delivering efficient processing power for real-time tasks. Its 4 KB of on-chip ROM and 128 bytes of RAM make it suitable for small to medium-scale projects requiring reliable data handling and program execution.  

Featuring a 24-pin DIP (Dual In-line Package), the PCB80C31BH-4-24P offers a compact footprint while maintaining versatility. It includes essential peripherals such as timers, serial communication interfaces, and multiple I/O ports, enabling seamless integration into industrial, automotive, and consumer electronics. The extended temperature range ensures stable operation in demanding environments.  

As a derivative of the Intel 8051 microcontroller, this component retains backward compatibility while offering enhanced performance. Its low-power consumption and durable design make it a preferred choice for cost-sensitive yet high-reliability applications. Engineers and developers appreciate its ease of programming and debugging, supported by a well-established ecosystem of development tools.  

The PCB80C31BH-4-24P remains a dependable solution for embedded systems requiring precise control, efficient processing, and long-term durability.

Application Scenarios & Design Considerations

CMOS single-chip 8-bit microcontrollers

Alternative Part Number

  • AT89C51-24PC --: Pin-compatible 8051 microcontroller with 4KB flash, 24 MHz rating, and DIP-40 package; widely available and a common drop-in replacement for the 80C31.
  • P89C51RB2HFA --: Direct successor from the same Philips/NXP 80C51 family with 24 MHz support and DIP-40 footprint, offering a smooth migration path.
  • W78E516B40PL --: 8051-compatible MCU in DIP-40 with 40 MHz capability and flash memory, suitable as a functional substitute when the original ROMless part is unavailable.
  • P80C31BH --: Same 80C31 8-bit microcontroller core in 40-pin DIP, pin-compatible and functionally equivalent to the original.
  • W78E51B-24 --: 8051-compatible MCU in 40-pin DIP rated to 24 MHz, suitable substitute when the original Philips part is unavailable.
