Hi @christophe_menard ,

In the checklist, we should add a check on the external watchdog, note that if the customer uses the OTA function, when upgrading the firmware, the time required after reset may reach a few seconds, which requires special attention from the external watchdog.

Does anyone help me to about the value of power consumption for KW54 in three modes( PMIC, DCDC, Bypass) ?

Hi Suleymansekerci,

Could you precise your request about the three modes( PMIC, DCDC, Bypass), please?

For your help, you could refer to the AN13230 Kinetis KW45 & K32W1 Bluetooth LE Power Consumption Analysis available in NXP site and playing with the KW45_BLE_power_profile_calculator_v1.5.xlsx file.

 

For your guidance, the most safe power is the buck mode (DCDC inside the Kinetis product)  for sure without any extra BoM cost.

Hi Marko,

The added components are not the same on the 3 use cases.

Hi Marko,

The valus are correct. The added components are not the same on the 3 use cases.

Hi, I am looking the "minimum BOM" document. At the end, there is a table with con-cell operation recommendation:

marko_pavlin_1-1680760460835.png

Is this OK? 10dBm <1mA, ... 0dBm : 4,5mA ?
