Description
The Real-Time Clock and Calendar (RTCC) module was designed to allow users to maintain accurate tracking for extended periods of time without the need for extensive CPU intervention. The module is optimized for battery powered LCD applications and is capable of providing extended battery life when applicable. The RTCC can be configured to run from multiple clock sources, including the option to use an external 32.768 kHz crystal oscillator attached to the Secondary Oscillator (SOSC) pins. It is capable of operating from a battery backup in the event of a VDD supply voltage power failure, which allows the RTCC and SOSC modules to continue running and prevents data loss. This technical brief will give an overview of the RTCC module and the integrated VBAT functionality.
