MM58167B General Description
The MM58167B is a low threshold metal gate CMOS circuit that functions as a real time clock in bus oriented microprocessor systems. The device includes an addressable real time counter, 56 bits of RAM, and two interrupt outputs. A POWER DOWN input allows the chip to be disabled from the rest of the system for standby low power operation. The time base is a 32.768 kHz crystal oscillator.
