Description and Introduction

80C51 8-bit microcontroller family 8K.64K/256.1K OTP/ROM/ROMless, low voltage 2.7V.5.5V, low power, high speed 33 MHz The **P87C58SBAA** from **PHILIPS** is an advanced 80C51-based microcontroller designed for embedded applications requiring high performance and reliability. Built on a robust CMOS architecture, it features an 8-bit CPU with enhanced processing capabilities, making it suitable for industrial control, automation, and communication systems.  

This microcontroller integrates **16 KB of OTP (One-Time Programmable) ROM**, ensuring secure firmware storage, along with **256 bytes of RAM** for efficient data handling. It supports a wide operating voltage range (2.7V to 5.5V), enhancing its adaptability in low-power and battery-operated devices.  

Key features include three **16-bit timer/counters**, a **programmable serial UART**, and **32 I/O lines**, providing flexibility for interfacing with peripherals. Additionally, the P87C58SBAA incorporates **watchdog timer** and **power-saving idle/power-down modes**, improving system stability and energy efficiency.  

With a **24 MHz maximum clock frequency**, it delivers fast execution speeds while maintaining low EMI emissions. Its compatibility with the 80C51 instruction set ensures seamless migration for legacy designs.  

The **P87C58SBAA** is an ideal choice for developers seeking a dependable, high-performance microcontroller with extended memory and versatile I/O capabilities, making it well-suited for demanding embedded applications.
