MSM6545/6575/6545L/6575L
Operatable at 0.9 V and Built-in Buzzer Circuit 4-Bit Microcontroller
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.
