Description and Introduction

CMOS single-chip 8-bit microcontrollers The **PCB80C51BH-3P** is a high-performance, 8-bit microcontroller based on the widely recognized 80C51 architecture. Designed for embedded applications, this component combines efficiency with versatility, making it suitable for industrial control, automation, and consumer electronics.  

Built with a robust CMOS process, the PCB80C51BH-3P operates at a clock frequency of up to 12 MHz, ensuring reliable performance in demanding environments. It features 4 KB of on-chip ROM, 128 bytes of RAM, and multiple I/O ports, providing ample resources for small to medium-scale projects. Additionally, its low-power consumption and integrated peripherals, including timers and serial communication interfaces, enhance its usability in battery-operated and space-constrained designs.  

The microcontroller supports in-system programming (ISP), allowing for flexible firmware updates without removing the chip from the circuit. Its 40-pin DIP package ensures easy integration into prototyping and production boards.  

With its proven architecture and dependable operation, the PCB80C51BH-3P remains a practical choice for engineers seeking a cost-effective yet powerful solution for embedded systems. Its compatibility with legacy 80C51 code further simplifies development, making it a reliable option for both new and existing projects.

Alternative Part Number

  • AT89C51-24PC --: Pin-compatible 8051 microcontroller with 4KB flash, direct drop-in replacement for the 80C51 in most DIP-40 sockets.
  • P89V51RD2BN --: NXP 8051-family MCU in DIP-40, same architecture and pinout as the original Philips device, with enhanced flash memory.
  • W78E516B40PL --: 8051-compatible microcontroller in DIP-40 with similar electrical characteristics, suitable as a functional substitute.
  • P80C51BH --: Original Intel 8051-family microcontroller in the same 80C51 core and DIP-40 package; functionally equivalent to the Hitachi part.
  • AT89C51-24PC --: Widely available 8051-compatible microcontroller with matching pinout and DIP-40 package, suitable as a drop-in replacement in most designs.
  • DS89C450-MNL --: 8051-compatible high-speed microcontroller in DIP-40 with similar pinout and enhanced performance, usable as an alternative when timing margins allow.
