MSM6351/6351L
Built-in 8 or 5 bit Serial Port and LCD Driver 4-Bit Microcontroller
GENERAL DESCRIPTION
The MSM6351/6351L is a low-power microcontroller manufactured in silicon gate CMOS
technology. Integrated into a single chip are ROM, RAM, five I/O ports, serial I/O port, time-
base counter, LCD driver, three interrupts, crystal oscillator, and voltage tripler.
The MSM6351/6351L, which can drive LCD display with higher-count segments, is best suited
to battery powered applications, such as watches and game machines.
The built-in 8-bit or 5-bit serial port provides a data communication capability with external
machines.
