Product De
The PT7C4337 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 PT7C4337. More
details are shown in section: overview of functions.
• Oscillator Stop Flag
• Operating range: 1.8V to 5.5V
