EM3027 General 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 temperat.
