K60 - Can I Leave Reset Pin Floating?

[hworrall]

We are designing a product that uses the K60 MPU. We are not planning to use the RESET_b pin (except for programming the MPU). Can this pin be left floating (it has internal pull up resistor) or should it be pulled high with an external resistor and or have a capacitor to 0V to protect it from EMC etc.

Hi Hugh Worrall,

    We highly recommend you add the 4.7K to 10K external pull up resistor in the RESET pin, and add 0.1uf capacitor to the ground, even you don't want to use it.

Wish it helps you!

Have a great day,
Kerry
