2 FRDM-MCXN947 functional description
This section describes the features and functions of the FRDM-MCXN947 board. You can use the functionality
described in this section as a reference while designing your own target board.
Note: For more details on the MCXN947 MCU, see MCX N94x, N54x Product Family Data Sheet and MCX
Nx4x Reference Manual.
2.1 Power supplies
The FRDM-MCXN947 board is powered with a P5V0 (5 V) power supply using one of the following source
options:
• P5V_USB_HS supply from high-speed (HS) USB2.0 Type-C connector (J11)
• P5V_HDR_IN supply from 5 V regulator populated at 3-pin jumper (J15) (Not populated by default)
• P5V0 supply from Arduino Shield compatible header, J3 (pin 10)
• P5V_MCU_LINK_USB supply from MCU-Link USB2.0 Type-C connector (J17)
The P5V0 supply is an input power supply on the board and is a source for secondary power supplies.
Other power supplies in the FRDM-MCXN947 board are through voltage regulators or are connected through
jumpers, which can be used to enable/disable a power supply.
Section 2.1 shows the system power circuit on the FRDM-MCXN947 board.
