11.1 S32K3X4EVB-S172 – Ethernet MII/RMII Interface
The S32K3X4EVB-S172 version incorporates a complete Ethernet interface providing a MII and/or RMII connectivity and LPSPI, I2Cx,
GPIOs [3] as digital signals and +3.3V and +12.0V (+5.0V as optional) to the ethernet SABRE connector.
Figure 18. S32K3X4EVB-S172 – Ethernet MII/RMII SABRE connector
Ethernet Connector - The EVB has a High-Speed Connector that is compatible with some external boards:
• ADTJA1101-RMII
