The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the FRDMDUALK3664EVB board.

2.2 Board Description
The FRDMDUALK3664EVB is a hardware tool for evaluation and development and is ideal for rapid prototyping of an isolated network high-speed transceiver. It can be used to evaluate the features of the MC33664A device.
The evaluation board allows the user to connect serial peripheral interface (SPI) signals from the MCU to the device and be able to create bit pulses transmission to the bus through the transformer. The messages received by the device can be converted bit by bit and transferred to the MCU by SPI.

3. Configure Hardware
The FRDMDUALK3664EVB is configured as a shield board for the S32K3x4EVB-Q172 board. It can also be used in a standalone configuration. For other configurations, check mechanical and electrical fit or use, for example, a breadboard design.
3.1 S32K3x4EVB-Q172 Board Configuration
The FRDMDUALK3664EVB is configured for the S32K3x4EVB-Q172 board by default. Ensure that the S32K3x4EVB is configured correctly before connecting both boards together.
Table 2 lists the relevant S32K3x4EVB-Q172 configurations required with the FRDMDUALK3664EVB. All other settings should use the default settings. For further details, see S32K3x4EVB-Q172 board user manual.
| Jumper | Configuration | Description |
|---|---|---|
J18 |
1-2 | VDD_HV_A = 5 V |
J19 |
2-3 | VDD_HV_B = VDD_HV_A |
When both boards are connected, the SPI and other signals are directly connected with suitable MCU pins. Power is supplied to the FRDMDUALK3664EVB through the 5.0 V from the S32K3x4EVB.
3.2 Standalone or Other Microcontroller Platforms
When the board is used in standalone or with other microcontroller platforms, the SPI signals must be manually connected to the MCU interface connectors.
Required power supply connections are:
- VCC5 must be provided with 5.0 V
- VIO must be provided with 3.3 V or 5.0 V depending on the required communication signal levels
