MSM6546L Overview
MSM6546/6546L is a 4-bit, low-power microcontroller manufactured in a CMOS silicon gate process. The microcontroller can be initialized and operated at the 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 ponents, a serial I/O port, a buzzer output circuit, an up/down counter, and LCD drivers. .. This IC can be driven by one battery and is well suited to products that need to be operated with low power consumption.
