5V Ordering Information Part Number Package IT7C4337WE Lead free and Green 8-Pin SOIC IT7C4337UE Lead free and Green 8-Pin MSOP IT7C4337ZEE Lead free and Green 8-Pin TDFN IT7C4337TE Lead free and Green 8-Pin TSSOP The IT7C4337 serial real-time clock is a low-power clock/calendar with two programmable time-of-day alarms and a programmable square-wave output.
Address and data are transferred serially via a 2-wire, bidirectional bus.
The clock/calendar provides seconds, minutes, hours, day, date, month, and year information.
The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year.
The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.
Table 1 shows the basic functions of IT7C4337.
