2-WIRE REAL-TIME CLOCK
Rev.3.1_02
The S-35399A03 is a CMOS 2-wire real-time clock IC which operates with the very low current consumption in the wide range
of operation voltage. The operation voltage is 1.3 V to 5.5 V so that the S-35399A03 can be used for various power supplies
from main supply to backup battery. Due to the 0.34 μA current consumption and wide range of power supply voltage at time
keeping, The S-35399A03 makes the battery life longer. In the system which operates with a backup battery, the included free
registers can be used as the function for user's backup memory. Users always can take back the information in the registers
which is stored before power-off the main power supply, after the voltage is restored.
The S-35399A03 has the function to correct advance / delay of the clock data speed, in the wide range, which is caused by the
crystal oscillation circuit's frequency deviation. Correcting according to the temperature change by combining this function and
a temperature sensor, it is possible to make a high precise clock function which is not affected by the ambient temperature.
Moreover, the S-35399A03 has a 24-bit binary up counter. This counter counts up every 60 seconds from power-on so that
users are able to grasp the elapsed time from power-on up to 30 years.
