3.1 Plug It In

The FRDM-A-S32K356 is a rapid prototyping board based on the S32K3X8EVB-Q289. As it is not intended for final production use, the board includes a primary power-supply option through USB PD connected to the FS26 SBC. Details of this configuration are provided in Table 1. See UM12542, FRDM-A-S32K356 Development Board User Manual for further details.

Table 1. Battery Voltage Input (VBAT) Supply

Mode	Max Voltage / Current Supported	Description
PD with USB Type-C Connector	Typical Input: +5 V/3 A Maximum Supported: Up to +20 V/3 A Note: Actual current depends on the capabilities of the connected USB Type-C power source	By default, the FRDM-A-S32K356 is powered via the `J11` USB Type-C connector. It is recommended to use the USB Type-C cable included in the box, or another cable that supports USB PD, to ensure full functionality of the board. Using an alternative cable may result in limited current supply and reduced performance. To power the board properly, a USB-C PD–compatible power source is needed, such as a USB-C PD charger or a laptop with PD support. While most modern laptops support USB PD, verify your device’s capabilities before use. Using an alternative cable may result in limited current supply and reduced performance. The FRDM-A-S32K356 supports input voltages up to 20 V. However, based on FS26 SBC recommendations, it is ideal to operate within 9 V, 12 V or 15 V ranges with at least 1 A. Achieving these voltages and current levels requires proper negotiation/communication between the USB PD source and the PD PHY (PTN5110). For guidance on implementing this negotiation with the S32K356, consult your local NXP field application engineer (FAE) or the code available in the NXP Application Code Hub (ACH) website. The FS26 manages power regulation by converting the VBAT input into stable voltage rails required by the S32K356’s power domains.
		Note: If a USB Type-A-to-USB Type-C cable is used to power the board, the integrated switch will not power off the board due to the lack of the cable control lines for power delivery. To avoid this issue, always use the cable provided.
		The second power supply method for the FRDM-A-S32K356 involves connecting an external +12 V/2 A power source to the barrel jack connector (`J10`).
Operation with Barrel Connector	+12 V/2 A	This option is disabled by default and requires manual soldering of the following components to enable it: `J10`: Barrel connector C1, C9: Input capacitors D1: Protection diode
Operation with Barrel Connector	+12 V/2 A	Once these components are populated, the board can be powered through `J10` as an alternative to USB Type-C PD.

Table 2. FRDM-A-S32K356 - Supply board method

Step sequence	Description
1.	Connect the USB Type-C cable to the `J11` connector to supply power to the board
2.	To power on the board, change the position of switch `SW5` to setting 2–3
3.	Verify that all power indicator LEDs on the board are illuminated

Supply Peripheral Jumpers	●	`JP5`	1 - 2	Selects the peripherals input supply
MCU Power Supply	●	VDD_HV_A	+3.3 V	The reference voltage of +3.3 V is supplied by the FS26 low-dropout 1 (`LDO1`) regulator and routed to the VDD_HV_A power domain of the S32K356 (5 V can be supplied on VDD_HV_A with R806 [FS26_VTRK1])
	●	VDD_HV_B	+3.3 V	The reference voltage of +3.3 V is supplied by the FS26 LDO2 regulator and routed to the VDD_HV_B power domain of the S32K356.
	●	V15	+1.5 V	The reference voltage of +1.5 V is supplied by the FS26 Core voltage (VCORE) regulator and routed to the V15 core power domain of the S32K356. (Optionally, the V15 rail can be powered through an external transistor controlled by the S32K358, so to enable this configuration, transistor Q5 and circuitry must be populated and solder jumper SJ4 must be properly routed)
