Description and Introduction

80C51 8-bit microcontroller family 16KB OTP/ROM, 512B RAM low voltage (2.7 to 5.5 V), low power, high speed (30/33 MHZ), two 400KB I2C interfaces The **P87C660X2FA** from **PHILIPS** is an advanced 8-bit microcontroller designed for embedded control applications. Built on a high-performance CMOS architecture, it integrates a powerful 80C51 CPU core with enhanced features, making it suitable for industrial, automotive, and consumer electronics.  

This microcontroller operates at frequencies up to **16 MHz**, offering efficient processing capabilities while maintaining low power consumption. It includes **32 KB of on-chip flash memory** for program storage and **1 KB of RAM** for data handling, providing ample resources for complex applications. Additional features include **three 16-bit timers/counters**, a **programmable watchdog timer**, and a **multi-source interrupt system**, ensuring robust real-time performance.  

The P87C660X2FA supports **full-duplex UART communication**, along with an **I²C-bus interface**, enabling seamless connectivity with peripheral devices. Its **low EMI emission** and **wide operating voltage range (2.7V to 5.5V)** enhance reliability in diverse environments.  

With its compact **PLCC-44 package**, the P87C660X2FA is ideal for space-constrained designs. Its combination of performance, flexibility, and durability makes it a preferred choice for engineers developing sophisticated embedded systems. Whether for automation, instrumentation, or smart devices, this microcontroller delivers precision and efficiency.

Alternative Part Number

  • AT89C51CC03CA-IM --: 8051-compatible microcontroller with CAN controller and 64KB flash, similar to the P87C660X2 in function and package, widely available and well documented.
  • W78E516DDG --: Classic 8051-core MCU with 64KB flash in a similar PLCC/QFP package, drop-in style replacement for legacy Philips 80C51 devices.
  • STC89C52RC-40I-PDIP --: Low-cost 8051-compatible MCU with 8KB flash, suitable for designs where the CAN feature is not required and a simpler 8051 core is acceptable.
  • AT89C51RC2-IM --: 8051-compatible microcontroller with similar on-chip Flash and I/O, widely available and pin/function compatible for most 87C660X2 applications.
  • W78E516B-40PL --: 8051-core MCU with embedded Flash, comparable peripheral set and 40-pin package, suitable drop-in replacement for legacy Philips 87C660 designs.
  • DS89C450-MNL --: High-speed 8051-compatible microcontroller with Flash program memory and similar I/O resources, usable as a functional substitute where timing is not critical.
