Hello Fred,
thank you for your question, I'm glad to help you.
I would suggest you to use our S9S12ZVL32F0MLC controller:
https://www.nxp.com/products/processors-and-microcontrollers/additional-mpu-mcus-architectures/s12-m...
This product can fulfill all required functions with small 32-pin package. It not comprises the dedicated RTC internal module, but the RTC functionality can be implemented by using external crystal and internal RTI functionality in clock generation module.
If you need more information you are welcome to ask me.
Best Regards,
Stano.
