MSM5832RS

The MSM5832RS is designed as one kind of metal-gate CMOS real time clock / calender for use in bus-oriented microprocessor applications. The on-chip 32.768 Hz crystal controlled osciliator time base is divided 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 of MSM5832RS include 12H / 24H format selection, leap year identification and manual +/- 30 second correction.

Features of the MSM5832RS are:(1)7 function - SECONDS, MINUTES, HOURS, DAY_OF_WEEK, DATE, MONTH and YEAR;(2)automatic leap year calendar;(3)12 or 24 hour format;(4)+/-30 second error correction;(5)4-bit data bus;(6)4-bit address;(7)read, write, hold and chip select inputs;(8)reference signal outputs - 1024, 1, 1/60, 1/3600 Hz;(9)single 5 V power supply;(10)back-up battery operation to VDD = 2.2 V.

The absolute maximum ratings of the MSM5832RS can be summarized as:(1)supply voltage: -0.3 to 7.0 V;(2)input voltage: -0.3 to VDD+0.3 V;(3)data I/O voltage: -0.3 to VDD+0.3 V;(4)storage temperature: -55 to +150 .
