3 Modular concept
The MPC5746R-176DS/252DS/144DSis part of a modular EVB hardware system that consists of:
• A common main board that provides power and access to common communication interfaces and
the MCU I/O port pins. The MPC5746R-176DS/252DS/144DSis compatible with the
MPC57XXXMB main board.
•Apackage-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.

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 1summarizes the jumper settings for the available power options.

If stand alone operation is desired, the following power supplies connections should be made on J6 (see
Table 2). If using the external supplies option, the user should reference the MPC5746R Data Sheet to
ensure that IDD requirements for each supply are met.
4.3 Clock Configuration Options
The EVB provides three clocking options that are controlled by jumpers:
• On board 20 MHz crystal oscillator
• On board oscillator
• SMA connector for external clock source
Table 3 summarizes the jumper settings for the available clock options. Note that some of these jumpers
are ‘non-populated’ by default and the clock source is configured by default for crystal oscillator
operation.

4.4 Micro Second Channel Connections
The microsecond channel signals on MSC1 are grouped at a SAMTECH ERF-8 connector on the EVB to
provide easier user access. This also allows better trace routing of the differential pair signals. The
connections of MSC1 on the connector are shown in Figure 2.

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.
Figure 2. Samtech ERF8 - MSC1 Connections (20-pin)
The following table lists the port and pins associated with each of the MSC channel signals.
4.5 ADC Channel Filters
For convenience, the EVB implements analog RC filters on one differential ADC channel pair, and two
single ended ADC channels. The single ended filter configuration is shown in Figure 3, and the differential
pair filter configuration is shown in Figure 4. The user may modify these component values for the desired
application.

4.8 I/O Connectivity and Port Routing
Most of the MCU’s I/Os are routed to the main mother board. 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 7lists the mapping from the MPC5746R device ports to the existing headers/ports on the
MPC57XXXMB motherboard, and to the FlexCAN, Ethernet, UARTand LinFlex drivers.
