General Description
MM58274C General Description
The MM58274C is fabricated using low threshold metal gate CMOS technology and is designed to operate in bus oriented microprocessor systems where a real time clock and calendar function are required. The on-chip 32.768 kHz crystal controlled oscillator will maintain timekeeping down to 2.2V to allow low power standby battery operation. This device is pin compatible with the MM58174A but continues timekeeping up to tens of years. The MM58274C is a direct replacement for the MM58274 offering improved Bus access cycle times.
