Description

The MM58174A is a low-threshold metal-gate CMOS circuit that functions as a real-time clock and calendar in bus-oriented microprocessor systems. The MM58174A includes an interrupt timer which may be programmed to one of three times. Timekeeping is maintained down to 2.2V to allow low power standby battery operation. The timebase is generated from a 32768 Hz crystal-controlled oscillator.
