Page 11: Power Supply
S32K344 NXP Semiconductors White Board Power supply The White Board requires an external power supply of 12V/1A, which is fed to the following devices on the board. • SBC FS26 – it powers the MCU with 5V (MCU VDD_HV_A domain), 3.3V (MCU VDD_HV_B domain) and 1.5V (MCU core). - Page 12 S32K344 NXP Semiconductors White Board Figure 6. Power supply topology The MCU has two power domains - VDD_HV_A and VDD_HV_B. On the white board, VDD_HV_A is supplied with 5V and VDD_HV_B is supplied with 3.3V and this configuration is fixed on the board. All 5V signals on the MCU are powered by VDD_HV_A and all 3.3V signals on MCU are powered by VDD_HV_B, so that the use of...

Page 15: General Functional Description
8.1 MCU HW configuration 8.1.1 MCU power supply configuration S32K344 has two power domains – VDD_HV_A and VDD_HV_B. They can be supplied with either 5V or 3.3V. See below figure for PINs distribution for the two domains. The white board optimizes the PINs assignment to minimize the usage of voltage level shifters. -
Page 16: Mcu Reset Control
S32K344 NXP Semiconductors White Board Figure 9. External crystals for MCU 8.1.3 MCU reset control The MCU RESET pin is bidirectional. When acting as input, MCU can be reset either by push button “SW1” on the board or SBC RESET signal. When acting as output, some MCU internal failures (such as watchdog timeout) will pull RESET pin low and SBC can sense the MCU reset event and react accordingly. -
