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 MSM6545 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 MSM6545 is driven by one battery and is well suited to products that need to be operated under low power consumption.
