The MPC5746R-176DS/252DS/144DS is compatible with the MPC57XXXMB main board. • A package-specific EVB to support all available production package types of the MPC5746R1. NOTE The MPC57XXXMB User Guide should be obtained to provide additional configuration information when used with the MPC5746-xxxDS. See Figure 1., “MPC5746R EVB and main board system” for an illustration of the modular EVB hardware system concept. 1.The MPC5746R Emulation Device (ED) requires separate hardware that may be ordered through your Freescale Salesperson or Representative. Qorivva MPC5746R-176DS/252DS Evaluation Board (EVB) User’s Guide, Rev. 1.6 2 Freescale Semiconductor EVB configuration MPC5746R-176DS/252DS MPC57XXXMB Figure 1. MPC5746R EVB and main board system 4 EVB configuration This section provides information on how to configure the jumper settings on the EVB. Default settings are marked as such. 4.1 Methods of operation Power to the EVB is supplied by one of two options: 1. The MPC57XXXMB main board generates the 5 V/3.3 V/1.25 V supplies and provides these to the EVB via the interface connectors. 2. In standalone configuration, external 5 V/3.3 V/1.25 V supplies are provided to the EVB via the terminal block. (This option provides minimal access to I/O) 4.2 Power source The default jumper settings are configured for using the EVB with the MPC57XXXMB main board. Power is supplied from the main board to the EVB via the two interface connectors. The EVB can also operate as a standalone device, where power can be supplied from an external power source. Table 1 summarizes the jumper settings for the available power options. Table 1.

Note that some of these jumpers are ‘non-populated’ by default and the clock source is configured by default for crystal oscillator operation. Table 3.

This also allows better trace routing of the differential pair signals. The connections of MSC1 on the connector are shown in Figure 2. Qorivva MPC5746R-176DS/252DS Evaluation Board (EVB) User’s Guide, Rev. 1.6 Freescale Semiconductor 5 EVB configuration Note that by default these signals are not routed to the motherboard via the motherboard interface connectors. However, zero ohm resistors may be installed at the reference designators listed in Figure 2 if the signals need to be routed to the motherboard for use as GPIO or other purposes. 1 VSS 2 VSS MSC1_SOUTN PA[7] VSS MSC1_SOUTP PA[8] VSS VSS MSC1_CLKN PA[9] 19 MSC1_CLKP PA[10] 20 MSC1_RX PA[11] MSC1_CS1 PA[12] MSC1_CS0 PA[13] Not populated 0 0 R2 R3 0 R4 0 R5 0 R14 0 0 R16 R15 Motherboard Connector Figure 2.

These include the pins associated with the FlexCAN, Ethernet, and LinFlex interfaces and other normal GPIO pins. The MPC57XXXMB provides physical layer drivers for these communication protocols. See the MPC57XXXMB User Guide for the correct jumper settings to enable and configure these drivers and associated circuits. Table 7 lists the mapping from the MPC5746R device ports to the existing headers/ports on the MPC57XXXMB motherboard, and to the FlexCAN, Ethernet, UART and LinFlex drivers.

To access the schematic open the bookmark window and click on the paper clip icon on the left side of the page. 9 EVB Errata EVB errata are listed in the following table. Errata List Affected Errata Description Workaround 176DS 1 Port pin PG[9] (CAN3RX) on the MPC5746R was routed to motherboard port pin PA[13] instead of PA[11]. PA[11] is also routed on the motherboard to J38, which is a selectable RX pin for the CAN transceiver. This prevents the CAN RX signal from being connected directly via motherboard trace to the PG[9] pin on the MPC5746R for the CAN3RX function. Yes 252DS No 144DS No To connect the RX signal from the CAN bus interface (J6) to the CAN3RX signal on the MPC5746R device at pin PG[9], place a wire jumper from PA[13] on the motherboard to pin 3 on J38.
