Getting to know the hardware

6.1 Kit overview
The FRDMDUALK3664EVB is a hardware tool for evaluation and development and is ideal for the 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.

6.1.1 FRDMDUALK3664EVB features

  • Two MC33664ATL1EG isolated communication transceivers in an SO16 package
  • Isolated communication by transformers with connector
  • Single TPL chain interface (requires two SPIs)
  • Dual TPL chain interface (requires three SPIs)
  • Compatible to S32K3x4EVB-Q172
  • Connector for FTDI USB-to-serial cable (TTL-232R-5V)
    Note: The FRDMDUALK3664EVB does not support the fault line feature.

6.2 Kit featured components
Figure 2 identifies important components on the board and Table 2 provides additional details on these components.

6.2.1 MC33664: Isolated network high-speed transceiver
6.2.1.1 General description
The MC33664 is a SMARTMOS transceiver physical layer transformer driver designed to interface a microcontroller conveniently to a high-speed isolated communication network. MCU SPI data bits are directly converted to pulse bit information and transferred to the bus network.
Slave response messages use the same structure to send pulse bit information to the MC33664, which is converted and sent back to the MCU as an SPI bit stream.

6.2.1.3 Features

  • 2.0 Mbit/s isolated network communication rate
  • Dual SPI architecture for message confirmation
  • Robust conducted and radiated immunity with wake-up
  • 3.3 V and 5.0 V compatible logic thresholds
  • Low Sleep mode current with automatic bus wake-up
  • Ultra-low radiated emissions
  • Option to access UART of S32K344 via J6

6.2.1.4 Modes of operation
The modes of operation followed by MC33664 for the VIO and EN pins are shown in Table 3.

Table 3. Modes of operation

Device mode EN pin VIO pin Comment
Normal 1 1 The MC33664 operates as a full transceiver. MCU messages

transmitted on the SPI_TX emerge on the SPI_RX for the MCU to read.
Sleep| 0| 1| In Sleep mode, the transceiver activates the INTB pin when a valid wake‑up sequence is detected. The INTB pin remains LOW until the rising edge of the EN pin places the device in Normal mode.

Configuring the 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.

7.1 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 12 lists the relevant S32K3x4EVB-Q172 configurations required with the FRDMDUALK3664EVB. All other settings should use the default settings. For further details, consult the S32K3x4EVB-Q172 board user manual [3].

Table 12. S32K3x4EVB-Q172 recommended setting

Jumper Configuration Description
J18 2-Jan VDD_HV_A = 5 V
J19 3-Feb 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.

Note: The S32K3x4EVB-Q172 requires an external 12 V 2 A power supply.

7.2 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 according to Table 7.
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
