Notes:
  1. Current for sleep mode is only for VDDAU. All other power pins are assumed to be unpowered.
  2. Maximum sleep power calculated for VDDAU = 3.465V
  3. Continuous transmission.
  4. Typical VDDP current when receiving data. Current is lower in other modes.
  5. Maximum power occurs during continuous transmission with VDDC = 1.89V and all power supplies = 3.465V
