DESCRIPTION
This version: Sep. 1998 MSM6051 Previous version: Mar. 1996
Built-in Melody Circuit and LCD Driver 4-Bit Microcontroller
The MSM6051 is a low-power microcontroller manufactured in plementary metal-oxide semiconductor technology. Integrated into a single chip are ROM, RAM, crystal oscillator, voltage doubler, timer, melody circuit, LCD driver, input port, and output port. Using the on-chip ROM for application code reduces power consumption. The MSM6051 is widely used in electronic products requiring low-power operation, such as stopwatches with lap time memory, calculator watches, and handy terminals.
