1 General Description

Feature Integration Technology Inc.

F15353

The F15353 which is a low current consumption 2- wire CMOS real-time clock operates under 1.3V to 3.6V. The

current consumption is only 0.55uA and operation voltage is 1.1V as time keeping. In a system that operates on a

backup battery, the free register incorporated in the real-time clock can be used for the user backup

memory function. The user register can hold data on a supply voltage as low as 1.1 V (min.), so the data stored

in the register before the main power supply was removed and can be recalled any time after the power is

reconnected.

A clock adjustment function that enables wide range correction of deviation in the frequency of the crystal

oscillator at a minimum resolution of 1 PPM is integrated in the F15353. The clock adjustment value can be set in

accordance with changes in the temperature. It is possible to make the realization of clock function that retains a

high degree of accuracy regardless of temperature variation by combining with a temperature sensor.
