a. The BCM4390 is functional across this range of voltages. Optimal RF performance specified in the data sheet,
however, is guaranteed only for 3.13V < VBAT < 4.8V.
b. The maximum continuous voltage is 5.25V. Voltages up to 6.0V for up to 10 seconds, cumulative duration over
the lifetime of the device are allowed. Voltages as high as 5.5V for up to 250 seconds, cumulative duration
over the lifetime of the device are allowed.
c. Programmable 2 mA to 16 mA drive strength. Default is 10 mA.
