Electrical Specifications

3.1 Absolute Maximum Ratings

CAUTION! The absolute maximum ratings in Table 1 and Table 2 indicate levels where permanent damage to the de-

vice can occur, even if these limits are exceeded for only a brief duration. Functional operation is not guaranteed un-

der these conditions. Operation at absolute maximum conditions for extended periods can adversely affect long-

term reliability of the device.

The values in Table 1 reflect absolute maximum ratings from the respective MCU and BCM43362 datasheets.
