Part Number: AM62P-Q1

Tool/software:

Hello,

as below show, does low frequency oscillators(32.768KHz) must be have ? and what's means "clock to Timers" , if we have PWM output in our real application, does this mean this 32.768KHz oscillator needed?

thanks!

Hi liujian zhan,

Speaking about Timers, there a good variety of functional clocks to select from:

Also, the 32.768k oscillator can be replaced with 32k clock divided from HFOSC clock or 32k RC clock:

Additionally, the 32.768k oscillator is used for the RTC module especially in during low-power modes.

You can skip the 32,768k crystal if the RTC is not required.

Regards,

Stan

Hi liujian zhan,

WKUP_LFOSC0 has limited use case.

We are recommending customers to provide provision to pulldown the Xi input when not used.

Refer below FAQ. We have schematics embedded with design notes that can be referenced during custom board design.
