Overview

S-35390A www.sii-ic.com © SII Semiconductor Corporation, 2004-2016 2-WIRE REAL-TIME CLOCK Rev.4.2_02 The S-35390A 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-35390A can be used for various power supplies from main supply to backup battery.

Due to the 0.25 μA current consumption and wide range of power supply voltage at time keeping, the S-35390A makes the battery life longer.

Key Features

Low current consumption: 0.25 μA typ. (VDD = 3.0 V, Ta = +25°C).
Wide range of operating voltage: 1.3 V to 5.5 V.
Built-in clock correction function.
Built-in free user register.
2-wire (I2C-bus) CPU interface.
Built-in alarm interrupter.
Built-in flag generator during detection of low power voltage or at power-on.
Auto calendar up to the year 2099, automatic leap year calculation function.
Built-in const.
