3. Plug It In

The FRDM-A-S32K358 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 UM12541, FRDM-A-S32K358 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: +20 V / 3 A Note: Actual current depends on the capabilities of the connected USB Type-C power source.	By default, the FRDM-A-S32K358 is powered via the `J11` USB Type-C connector. It is recommended to use the USB Type-C cable included in the box, or any cable that supports USB Power 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-S32K358 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 level requires proper negotiation between the USB PD source and the PD PHY (PTN5110). For guidance on implementing this negotiation with the S32K358, consult local NXP field application engineer (FAE) or available code 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 S32K358’s power domains. Note: If a USB-A to USB Type-C cable is used to power the board, the integrated switch will not power off the board due to lack of control lines for power delivery. Always use the cable provided.
Normal Operation with Barrel Connector	+12 V / 2 A	The second power supply method for the FRDM-A-S32K358 involves connecting an external +12 V / 2 A power source to the barrel jack connector (J10). 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 Once these components are populated, the board can be powered through `J10` as an alternative to USB Type-C PD.
