REAL TIME CLOCK/CALENDAR MSM5832MPU Real-Time Clock/Calendar

The MSM5832 is a monolithic, metal-gate CMOS integrated circuit that functions as a real-time Clock calendar for use in bus-oriented Microprocessor applications. The on-chip 32,768 Hz crystal controlled Oscillator time base is counted down to provide addressable 4-bit I/O data of seconds, minutes, hours, day-of-week, date, month, and year. Data access is controlled by 4-bit address, chip select, read, write and hold inputs. Other functions include 12H/24H format selection, leap year identification and manual 30 second correction. The MSM5832 normally operates from a 5 volt 5% supply. Battery back-up operation down to 2.2 volts allows continuation of time keeping when main power is off. One test input facilitates rapid testing of the time-keeping operations. The MSM5832 is offered in a 18-lead dual-in-line plastic (RS suffix) package.
