GENERAL DESCRIPTION

MSM6545/6575/6545L/6575L is a 4-bit, low-power microcontroller manufactured in a CMOS

silicon gate process. The microcontroller can be initialized and operated at a low supply voltage

of 0.9 V.

This single 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, and an updown counter.

This IC is driven by one battery and is well suited to products that need to be operated under

low power consumption.

FEATURES

• The IC can be initialized and operated even at a low voltage of 0.9 V.

• Low power consumption
