The P87C51FB-4A,512 is a single-chip 8-bit Microcontroller manufactured in advanced CMOS process and is derivative of the 80C51 microcontroller family. The device have the instruction set as the 80C51. The device have four 8-bit I/O ports, three 16-bit timer/event counters, a multi-source, four-priority-level, nested interrupt structure, an enhanced UART and on-chip oscillator and timing circuits. For systems that require extra memory capability up to 64k bytes, each can be expanded using standard TTL-compatible memories and logic. Its added features make it an even more powerful microcontroller for applications that require pulse width modulation, high-speed I/O and up/down counting capabilities such as motor control. It also has a more versatile serial channel that facilitates multiprocessor communications.
