Product Summary

The IDX110M00-LC is an Ultra Low Power CMOS real-time clock IC with two serial interface modes: I2C or SPI. The interface mode is selected by the chip version (see §12). The basic clock is obtained from the 32.768 kHz crystal oscillator. A thermal compensation of the frequency is based on the temperature measurement and calculation of the correction value. The temperature can be measured internally or be input by an external application to the register. It is ideal for: (1)Utility meters; (2)Battery operated and portable equipment; (3)Consumer electronics; (4)White/brown goods; (5)Pay phones; (6)Cash registers; (7)Personal computers; (8)Programmable controller systems; (9)Data loggers.
