Power dissipation at

TA = 85 °C (suffix 6 version)

UFQFPN32

See Section 6.3 for appropriate thermal

resistance and package. Power

dissipation is calculated according to

ambient temperature (TA), maximum

junction temperature (TJ), and selected

thermal resistance.

1. When RESET is released functionality is guaranteed down to VBORx min.

2. When the 2.4 GHz RADIO is active, when inactive supply can go down to 0 V.
