SERIAL RTC MODULE WITH ALARM AND TIMER FUNCTIONS
Built-in crystal unit allows adjustment-free efficient operation.
Serial interface which can be controlled by three signal lines.
Alarm interrupt function for day of week, day, hour, and minute.
Regular cycle interrupt function which can be set up between 1/4096 second
and 255 minutes .
Dedicated interrupt output of the two systems (alarm and regular cycle) which
allows software masking.
Ability to detect stopping of oscillation and time update.
Automatic adjustment for leap year.
Wide range of interface voltage between 1.6 and 5.5V.
Wide range of clock voltage between 1.6 and 5.5V.
Low power consumption at 0.5μA/3V. (Typ.)
Available in two small packages:SOP14-pin and VSOJ20-pin. This is
mostly suited for high density mounting.
