GENERAL DESCRIPTION
MSM6576 is a 4-bit, low-power microcontroller that is manufactured in a CMOS silicon-gate
process. The microcontroller can be started and operated at a low supply voltage of 0.9 V.
This device contains a crystal oscillator circuit, voltage converter circuits, a time base counter,
a ROM, a RAM, a stack RAM, I/O ports, interrupt function components, a serial I/O port, a
buzzer output circuit, a level detector, and a differential amplifier.
This IC is driven by one battery and is well suited to products that need to be operated under
low power consumption.
