IZ1325 Datasheet PDF

Integral IZ1325

The IZ1325 high-precision real-time clock circuit with thermal compensation and built-in quartz resonator, provides high accuracy counting the current time of the, generation of 6 system interruptions and two independent event signals. The device provides both 24/12-hour operation modes and contains the built-in supply control circuit, frequency adjustment circuit for high accuracy of the system generator. The IZ1325 support data and command exchange by means of standard 2-wire interface (I2C-bus).
