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 MM58274CN offering improved Bus access cycle times.

Parametrics

MM58274CN absolute maximum ratings: (1)DC Input or Output Voltage: -0.3V to VDD a 0.3V; (2)DC Input or Output Diode Current: ±5.0 mA; (3)Storage Temperature, TSTG: -65℃ to a150℃; (4)Supply Voltage, VDD: 6.5V; (5)Power Dissipation, PD: 500 mW; (6)Lead Temperature (Soldering, 10 seconds): 260℃.

Features

MM58274CN features: (1)Timekeeping from tenths of seconds to tens of years in independently accessible registers; (2)Leap year register; (3)Hours counter programmable for 12 or 24-hour operation; (4)Buffered crystal frequency output in test mode for easy oscillator setting; (5)Data-changed flag allows simple testing for time rollover; (6)Independent interrupting time with open drain output; (7)Fully TTL compatible; (8)Low power standby operation (10 mA at 2.2V); (9)Low cost 16-pin DIP and 20-pin PCC.
