a. The CYW43340 is functional across this range of voltages. Optimal RF performance specified in the data sheet, however, is guaranteed only for 3.0V < VBAT
< 4.8V.
b. The maximum continuous voltage is 4.8V. Voltages up to 5.5V for up to 10 seconds, cumulative duration, over the lifetime of the device are allowed. Volt-
ages as high as 5.0V 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.
