Recommended Operating Conditions and DC Characteristics
Caution! Functional operation is not guaranteed outside of the limits shown in Table 27. Operation
outside these limits for extended periods can adversely affect long-term reliability of the device.
Note: For DC absolute maximum rating (AMR), see Table 24 on page 97.

pF
a. The BCM43455 is functional across this range of voltages. Optimal RF performance specified in the data sheet,
however, is guaranteed only for 3.2V < VBAT < 4.8V.
b. The maximum continuous voltage is 5.25V.
c. Programmable 2 mA to 16 mA drive strength. Default is 10 mA.
