Product Summary
The MM58274cn is a Microprocessor 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 of the MM58274cn will maintain timekeeping down to 2.2V to allow low power standby battery operation. The MM58274cn is a direct replacement for the device offering improved Bus access cycle times.
