Description and Introduction

CMOS single-chip 8-bit microcontrollers The **PCB80C31BH-3-16P** is an 8-bit microcontroller from Philips (now NXP Semiconductors), designed for embedded control applications. As part of the 80C51 family, it combines high performance with low power consumption, making it suitable for industrial, automotive, and consumer electronics.  

This 16-pin DIP (Dual In-line Package) variant operates at a clock speed of up to 16 MHz, delivering efficient processing for real-time tasks. It features 128 bytes of on-chip RAM and 4 KB of ROM, providing sufficient memory for small to medium-scale applications. The microcontroller supports standard 80C51 instruction set compatibility, ensuring ease of integration with existing designs.  

Key peripherals include two 16-bit timers/counters, a full-duplex UART for serial communication, and 32 I/O lines for interfacing with external components. Its low-power idle and power-down modes enhance energy efficiency in battery-operated systems.  

The **PCB80C31BH-3-16P** is well-suited for applications requiring reliable control, such as sensor interfaces, motor control, and automation systems. Its robust architecture and legacy compatibility make it a practical choice for engineers working with 8-bit microcontroller platforms.  

For detailed specifications, refer to the official datasheet to ensure proper implementation in your design.

Application Scenarios & Design Considerations

CMOS single-chip 8-bit microcontrollers

Alternative Part Number

  • AT89C51-24PC --: Pin-compatible 8051 microcontroller with 4KB flash, widely available and a common drop-in replacement for the 80C31 in many legacy designs.
  • P89C51RD2HBP --: Direct 8051-family successor from the same Philips/NXP lineage with compatible pinout and instruction set, easing migration.
  • W78E516B40PL --: 8051-compatible MCU with similar 40-pin DIP footprint and timing, suitable as a functional substitute for older 80C31 designs.
  • P80C31BH --: Original 8051-family microcontroller in the same 80C31 ROM-less configuration, widely available and functionally compatible with the PCB80C31BH.
  • AT89C51 --: Popular 8051-compatible microcontroller with on-chip Flash, can replace the ROM-less 80C31 in most designs with minor pin/software considerations.
  • DS80C310 --: High-speed 8051-compatible microcontroller from a different series, offering drop-in style compatibility for many 80C31 applications.
  • P80C31BH --: Original 8051-family microcontroller in the same 80C31 ROMless configuration; Intel is the originator of the MCS-51 architecture and this part is functionally equivalent at 16 MHz.
  • AT89C51 --: Widely available 8051-compatible microcontroller with 4 KB flash, pin-compatible with the 80C31 in most 40-pin DIP designs and easy to source.
  • DS80C310 --: Fast 8051-compatible ROMless microcontroller with similar pinout and higher throughput, suitable as a drop-in upgrade for 80C31-based designs.
