1. Overview
This module is a serial interface real time clock that has a built-in crystal unit.
The module offers many functions such as clock & calendar circuitry with automatic leap year adjustment (from
seconds to year), alarm, and Timer interrupt. In addition, it can detect stopping of oscillation and time update.
The serial interface can be controlled by three signal lines, and it enables minimum number of ports required in the
system.
Because it is available in two small packages, SOP-14 pin and VSOJ-20 pin and SON-22 pin, in high density mounting,
it is ideally suited for applications such as mobile phones, handy terminals or other small electronic systems.
