CC2640R2F: RESET_N low duration is 1us

Amelie Zheng

Part Number: CC2640R2F

Hi Team,

In 5.27 Timing Requirements, it said that the RESET_N low duration is 1us.

Does it mean when power-up, the RESET_N need to keep low level voltage at least 1us, after 1us we could let RESET_N high?

Thanks!

Hi Team，

cc2640r2f needs to be kept at least 1us low when it is powered on,Is it the same with the midway reset after power on? Is there any requirement for down time sequence?

Thanks！

The requirement is the same regardless of when the reset is issued.
