I have checked that there is no separate RTC power supply pin on the chip hardware. Can we only adopt the solution of using an external RTC clock chip?</P> Fri, 14 Mar 2025 09:30:04 GMT https://community.nxp.com/t5/S32K/S32k144-maintains-normal-operation-of-RTC-in-case-of-powerdown/m-p/2061974#M46784 kane123Hu 2025-03-14T09:30:04Z Re: S32k144 maintains normal operation of RTC in case of powerdown https://community.nxp.com/t5/S32K/S32k144-maintains-normal-operation-of-RTC-in-case-of-powerdown/m-p/2063905#M46917 <P>Yes, it will be needed to use external RTC device.</P> Tue, 18 Mar 2025 15:09:20 GMT https://community.nxp.com/t5/S32K/S32k144-maintains-normal-operation-of-RTC-in-case-of-powerdown/m-p/2063905#M46917 davidtosenovjan 2025-03-18T15:09:20Z
