SM320F28335-EP: Power Sequencing

gene glick

I did not see a power sequencing spec in the data sheet. Is there any requirement as to power sequencing? Does 3.3V IO need to be applied before/after core 1.8V? Is there a requirement for the rise-rate on the supplies?

thanks

I must have made a type when searching....I see section 6.8 in the data sheet discusses power sequencing. There is a preferred turn on, 1.9V first, 3.3V 2nd.

Hi Gene,

Glad to hear you were able to find this on your own and share your findings. Closing the thread.
