KE04 RESET pin handling

jun1 — Tue, 16 Jun 2020 03:24:37 GMT

I am always indebted.
As for the title, the KE04(MKE04Z128VLD4) reset pin, is it okay if it is left open if only power-on reset is used?
If opening is not desirable, do you need to connect something like CR to the terminals? Please tell us the recommended constants in that case.

Thank you.

Hi jun yamada

To boot normally, please add 4.7K to 10K external pull up in the reset pin, and 0.1uf capacitor to ground.

Normally, use the above setting, will has no issue, but if you just leave it open, your boot may be failed.

To work stably, please add the external component.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Kerry
