Notes:

1.

Typical values in the data sheet apply at VDD = 3.3 V and 25 °C unless otherwise stated.

2.

All minimum and maximum specifications in the data sheet apply across the recommended operating conditions for

minimum VDD =2.7 V.

3.

Operation at minimum VDD is guaranteed by characterization when VDD voltage is ramped down to 2.0 V. Part

initialization may become unresponsive below 2.3 V.
