    1. Introduction This user guide details the setup and configuration of the NXP MPC5748G Low Cost Evaluation Board (hereafter referred to as the LCEVB). The LCEVB is intended to provide a mechanism for easy evaluation of the MPC5748G family of microcontrollers, and to facilitate basic hardware and software development.

    For flexibility, the CAN transceiver I/O is connected to a 0.1” header (P2 for CAN0 / P3 for CAN1) rather than using non-standard DB9 connectors. The pinout of these headers is shown below.

    5.2. LIN Interfaces (P6, P7) The LCEVB incorporates two LIN transceiver circuits connected to MCU LIN0 and LIN1, using an NXP MC33662 transceiver. The MPC5748G LIN0 supports both master and slave modes whereas LIN1 only supports master mode. On the LCEVB, the LIN0 transceiver is configured as slave mode by default. Master mode operation is possible by either populating a zero ohm resistor (R143) or buy fitting a jumper header (J2) –...

  • Page 13: Ethernet Interface (P5)

    The transceiver is connected to a pulse J1011F21PNL RJ45 connector which includes a built-in isolation transformer. There is no hardware configuration needed. If you require RMII mode or access to both Ethernet ports on the MPC5748G, please purchase the MPC5748G customer EVB and appropriate daughter cards.

  • Page 15: User Switches (Sw4, Sw5)

    Note that POSN 0 will ensure that no voltage is applied to the pads. This allows the pads to be used as normal GPIO (with 10K pulldown) and accessed at the respective pads on the GPIO matrix area. MPC5748G Low Cost EVB User Guide, User Guide, Rev. 1, 08/2016 NXP Semiconductors Arrow.com.

    Note that this circuit provides a very rough way to evaluate the ADC. There is a small current limiting series resistor network to limit the injection current to around 4.4 mA. MPC5748G Low Cost EVB User Guide, Rev. 1, 08/2016 NXP Semiconductors Arrow.com.
