Real-Time Clock with I2C or SPI Interface, Crystal Temperature Compensation, Battery Switchover and Trickle Charger

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 ·Fully operational from 2.1 to 5.5V\n·Supply current typically 600 nA at 1.4V\n·Thermal compensated crystal frequency\n·Oscillator stability 0.5 ppm / Volt\n·Counter for seconds, minutes, hours, day of week, date months, years in BCD format and alarm\n·Leap year compensation\n·16-bits timer with 2 w;
