GENERAL DESCRIPTION
This version: Sep. 1998 MSM6576 Previous version: Mar. 1996
Operatable at 0.9 V and 7-level Detector 4-Bit Microcontroller
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.
