Overview

EM MICROELECTRONIC - MARIN SA EM3027 Real Time Clock with I2C or SPI, Crystal Temperature Compensation, Battery Switchover and Trickle Charger Description The EM3027 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.
The chip provides clock and calendar information in BCD format with alarm possibility.
