a. The CYW54907 is functional across this range of voltages. Optimal RF performance specified in the data sheet, however, is guaranteed only
for 3V < VBAT < 4.8V.
b. VDD3P3RF, which is an internally generated supply, can drive this node. There is sufficient current and the appropriate state is maintained
during hibernation and sleep cycles.
c. Internally generated supply.
d. Programmable 2 mA to 16 mA drive strength. Default is 10 mA.
