4 Conclusion

This technical brief provides an overview of the RTCC module and the integrated VBAT capabilities that it offers. The Real Time Clock Calendar (RTCC) module allows users to maintain accurate time tracking in applications for extended periods while reducing software overhead. Some advantages to the RTCC module in the PIC16(L)F19197 family of devices are the low power consumption, versatility, and the minimal software requirements needed to implement it. The RTCC module has built-in auto adjust functionality to calibrate the clock source, to help maintain accurate time keeping for longer periods. For more details about this module, refer to the RTCC chapter of the device data sheet, utilize the MPLAB® Code Configurator plug-in available in MPLAB X IDE, or browse the MPLAB Xpress example library.

Tip: Complete working demo code for the RTCC module with VBAT functionality can be found on the MPLAB Xpress Cloud-Based IDE platform. See the example section here.
