Product Summary

The MSM6575 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 MSM6575 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 MSM6575 is driven by one battery and is well suited to products that need to be operated under low power consumption.

Parametrics

MSM6575 absolute maximum ratings: (1)Power Supply Voltage, VSS1 at Ta = 25℃: –6.0 to +0.3v; (2)Input Voltage, VINat Ta = 25℃: VSS1 – 0.3 to +0.3 V; (3)Output Voltage, VOUT at Ta = 25℃: VSS1 – 0.3 to +0.3v; (4)Storage Temperature, TSTG: –55 to +125 ℃.
