3 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 device

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

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 microprocessor and CYW43362 datasheets.

Notes:

1. VDD_3V3 and VDD_WIFI must be at the same voltage when using the Wi-Fi subsystem

2. The performance of the Wi-Fi subsystem is degraded significantly at low voltages
