General Description
The HT1382 is a low power real time clock device
with two serial interface: I2C or 3-wire. The interface
mode is selected by the chosen chip version. The
device provides both clock and calendar information
in BCD format and also includes alarm functions. The
calendar is accurate until the year 2099 and includes
automatic leap year correction.
An external 32768Hz crystal is used as the device
oscillator for device timing for which is provided
an integrated crystal load capacitance of 12.5pF.
The device includes a crystal oscillator temperature
compensation function and internal power control
circuitry detects power failures and automatically
switches to the battery supply when a power failure
occurs.
