PCA21125 RTC Code

AshBirari — Tue, 12 Dec 2023 09:00:36 GMT

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

Does this Super Capacitor / back up battery connected externally to RTC chip ?

Hello Ashwini,

Yes, externally only.
