hi I am using S32K344NHT1MPBST nxp controller. If i used 3.3V and 1.5V from different power supplies is it required power sequence. I am unable to find the this power sequence info from data sheet and Reference manual. pls advice for power sequence.
Take a look at the Hardware Design Guidelines for S32K3xx Microcontrollers.
Download the S32K3 MCUs for General Purpose – Hardware Design Package. You will find the S32K3xx - Hardware Design Guidelines.pdf in it (S32K3_HW-DesignPackage.zip\01 - S32K3 - Hardware Design Guidelines).
