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.

EM MICROELECTRONIC - MARIN SA EM3027 Real Time Clock with I2C or SPI, Crystal Temperature Compensation, Battery Switchover and Trickle.

 Fully operational from 2.1 to 5.5V  Supply current typically 600 nA at 1.4V  Thermal compensated crystal frequency  Oscillator stability 0.5 ppm / Volt  Counter for seconds, minutes, hours, day of week, date months, years in BCD format and alarm  Leap year compensation  16-bits timer with 2 working modes  Two low voltage detection levels VLow1, VLow2  Automatic supply switchover  Serial communication via I2C (I2C-bus specification Rev. 03 compatible.
