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 **P87C54UFBB** from PHILIPS (now NXP Semiconductors) is an 8-bit microcontroller belonging to the **80C51** family. Designed for embedded control applications, it combines high performance with low power consumption, making it suitable for industrial, automotive, and consumer electronics.  

Built around an enhanced **8051 core**, the P87C54UFBB features **16 KB of OTP (One-Time Programmable) ROM**, **256 bytes of RAM**, and a versatile set of peripherals, including **32 I/O lines, three 16-bit timers/counters, and a full-duplex UART** for serial communication. Its **12-clock or 6-clock machine cycle option** allows flexibility in balancing speed and power efficiency.  

With an operating voltage range of **4.5V to 5.5V** and robust EMI suppression, this microcontroller ensures reliable performance in noisy environments. It also supports **in-circuit programming (ISP)**, simplifying firmware updates during development.  

The **P87C54UFBB** is housed in a **PLCC-44 package**, offering compact integration for space-constrained designs. Its compatibility with the 80C51 instruction set ensures seamless migration for legacy applications while providing modern enhancements.  

Ideal for cost-sensitive yet performance-driven projects, the P87C54UFBB remains a dependable choice for designers seeking a proven microcontroller solution.
