Descriptions:

The Intel S87C51FC is a member of the MCS-51 microcontroller family, designed for embedded control applications. It features an 8-bit CPU, 8 KB of mask-programmable ROM, and 256 bytes of RAM. It supports standard 8051 instruction set and peripherals, including timers, UART, and multiple I/O ports.

Key Features:

• High-performance 8051 core with 12 MHz clock speed
• 8 KB on-chip ROM (factory-programmed, not erasable)
• 256 bytes of internal RAM
• 32 programmable I/O lines (4 ports)
• Full-duplex UART for serial communication
• Two 16-bit timer/counters
• Power-saving idle and power-down modes
• Boolean processor for bit manipulation
• Wide operating voltage range (4.5V–5.5V)

This microcontroller is commonly used in industrial control, automation, and embedded systems where a mask ROM version is preferred for high-volume production.

*(Note: The S87C51FC is a mask ROM variant and does not support in-system reprogramming.)*
