LMK05028: I2C I/F and "PDN"

Hello,

We don't have this specified on the datasheet. I2C access is fairly immediate, from personal use it's never been that I couldn't communicate after powering up the device but this is all through manual testing.

The timing wouldn't be any different out of PDN, again fairly immediate, but we don't have this specified on the datasheet either.

If there's a specific number you're looking for let me know.

Thanks and regards,

Amin

Amin-san,

Thank you for your reply !

I'm very sorry that you do not have the specifications...

But do you have "about" specification number about both items?

"Rough" number is welcome and the data would be very helpful for me.

Thanks and Regards,

Hi,

Let me inform you the specific numbers about I2C and PDN as below.

Both numbers are OK for the device to work normally, right?

 -I2C : the access start time from "release Power Down" is 500mSec(min)

 -PDN : 10mSec(min) assert(=low)

Though I think both (500mSec and 10mSec) numbers are enough value, let me ask you if the numers are OK for sure.

Thank you and Regards,

Hi,

I believe those numbers should be okay, really with more than enough margin. But I will double check with the designer and confirm.
