DESCRIPTION
The 87L51FA and 87L51FB Single-Chip 3.0V 8-Bit Microcontrollers
are manufactured in an advanced CMOS process and are
derivatives of the 80C51 microcontroller family. The 87L51FA/B has
the same instruction set as the 80C51.
This device provides architectural enhancements that make it
applicable in a variety of applications for general control systems.
The 87L51FA contains 8k
×
8 memory and the 87L51FB contains
16K
×
8 memory, a volatile 256
×
8 read/write data memory, four
8-bit I/O ports, three 16-bit timer/event counters, a Programmable
Counter Array (PCA), a multi-source, two-priority-level, nested
interrupt structure, an enhanced UART and on-chip oscillator and
timing circuits. For systems that require extra capability, the
87L51FA/B can be expanded using standard 3.3V 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.
