SW1 |
Reset button |
Resets the target MCU. This causes peripherals to reset to their default state. After this, MCU ROM bootloader will be executed. LED D1 turns on at SW1 press. |
|
SW2 |
User PB |
General purpose input. This pin supports low-power wakeup capabilities through Wake-Up Unit (WUU). |

User indicator, indicates system activity |
Power Configurations (KW47-M2)
- Populate J9 PWR connector. To run KW47 M2 as standalone, supply 3.3V to P3V3_DUT power rail
Figure 1 J9 M10
Configuration (KW47-M2)
To get the KW47 M2 up and running, you need to select a power configuration through JP5 jumper. For more information on KW47 power configurations, refer to RM:

Part Identifier |
pin |
Description |
|
JP5 |
1-2 |
1-2 shorted (default setting): Sets target MCU to DCDC mode. This mode is the recommended configuration. |
|
JP5 |
3-4 |
3-4 shorted: Sets target MCU to LDO mode. |
External power configuration (KW47-M2)
Enable KW47-M2 by supplying power through J9 connector:
Note: When using DCDC or LDO mode, it is recommended to supply P3V3_DUT power rail only.

Part Identifier |
pin |
Description |
|
J9 |
5 |
Use this pin to supply P3V3_DUT power rail with 3.3V. To get KW47-M2 up and running, it is recommended to set KW47 to DCDC mode and supply P3V3_DUT only. |
|
J9 |
3 |
Use this pin to supply P1V8_LDO power rail with 1.8V. This power rail is intended for an accurate control of VDD_RF power domain, but it is not necessary. |
|
J9 |
1 |
Use this pin to supply P1V1_EXT power rail with 1.1V. This power rail is intended for an accurate control of VDD_CORE power domain, but it is not necessary. |
Programming the NBU in the KW47-M2 board
The following steps guide you to program the NBU software for the KW47-M2
- Place a jumper on the JP4 header while holding down the reset button (SW) on the module board. Then, connect the USB cable to the J8 connector (USB-to-serial bridge) and plug it into your computer. After the USB cable is connected, release the reset button.
- Verify what COM Port was assigned to your KW47-M2 board. You can check the COM Port assigned in the Windows “Device Manager” program. Search for “Ports (COM & LPT)” and save the COM Port number. In this example the COM Port assigned was “COM19”
- Navigate to your computer to the MCU-Link installation folder. The default installation path is located at “C:\nxp\LinkServer_25.3.31\MCU-LINK_installer
- Locate the “bin” folder and open it. Run the script “blhost” within a windows command prompt.
Type “blhost.exe -p COMX write-memory 0x48800000”, drag and drop the NBU binary file. When the process is ready you will see the response status "success"
