Hello NXP ,
Can you provide me a PCA21125 RTC sample code/project for SPI communication ?
Does PCA21125 has Super capacitor for battery backup or any inbuilt battery is given ?

Hello Ashwini,
1. As far as I know, there is currently no sample code/project available for PCA21125 RTC from NXP.
2. No. For more information on backup power supply, please refer to the UM10301, Chapter 13.
BR, Tomas
