Notes:
1. Typical values in the data sheet apply at V_DD = 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 V_DD = 2.7 V.
3. Operation at minimum V_DD is guaranteed by characterization when VDD voltage is ramped down to 2.0 V. Part
initialization may become unresponsive below 2.3 V.
