Description
The MM58274C-12 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 all
Features
- Y Same pin-out as MM58174A MM58274B MM58274C and MM58274
Y Timekeeping from tenths of seconds to tens of years in independently accessible registers
Y Leap year register Y 12 hour operation only Y Buffered crystal frequency output in test mode for easy
oscillator setting Y Data-changed flag.
