Hello,

My customer is searching CPU for their DCDC system in Automotive Application and considering TMS320F280039C by TI, because customer needs the switching frequency to be high ~100KHz. Does S32K310 have that capability?

Hi,

Thank you so much for your interest in our products and for using our community.

Yes! 100kHz can be archived with S32K310, for example with eMIOS:

For generate a PWM signal of 100 kHz with eMIOS clock frequency of 120MHz:
1s -> 120MHz (120,000,000 ticks)
100kHz = (1/100,000)s
->120,000,000 *(1/100,000) = 1,200 ticks
Max ticks for eMIOS are 65,534 (16 bits).

Hope it helps you.

Have a nice day!
