MPC5777C EVB User Guide, Rev. 1
The EVB system consists of a motherboard and a daughter card, both with distinct features.
The Mother Board provides the following key features:
• Support provided for different MPC57xx MCUs by utilizing MCU daughter cards
• Single 12 V external power supply input with four on-board regulators providing all of the
necessary EVB and MCU voltages; power supplied to the EVB via a 2.1mm barrel style power jack
or a 2-way level connector; 12 V operation allows in-car use if desired
• Master power switch and regulator status LEDs
• Two 240-way high-density daughter card expansion connectors allowing connection of the MCU
daughter card or a custom board for additional application specific circuitry
• All MCU signals readily accessible at a port-ordered group of 0.1inch pitch headers
• RS232/SCI physical interface and standard DB9 connector
• LINFlexD interface , Ethernet interface
• 2 CAN interfaces, one configurable to be connected to one out of two CAN modules, and one
connected to a dedicated third CAN module
• Variable resistor, driving between 5 V and ground
• 4 user switches and 4 user LEDs, freely connectable
• Liberal scattering of GND test points (surface mount loops) placed throughout the EVB
**Mother Board has FlexRAY connector, but this feature is not used on MPC5777C
The daughter cards provide the following features:
•
MCU (soldered or through a socket)
• 40MHz onboard clock oscillator circuit in EVB for MCU Clocking
• User reset switch with reset status LEDs and Power Indication LEDs
• Standard 14-pin JTAG debug connector and 50-pin SAMTEC Nexus connector
• USB (Type B) / UART transceiver to interface with MCU
• Liberal scattering of ground and test points (surface mount loops) placed throughout the EVB
• Power SBC for standalone function of Daughter Card
• 1 CAN and 1 LIN connector supported by Power SBC
NOTE
To alleviate confusion between jumpers and headers, all EVB jumpers are
implemented as 2 mm pitch whereas headers are 0.1in. (2.54 mm). This
prevents inadvertently fitting a jumper to a header.
CAUTION
Before the EVB is used or power is applied, please fully read the following
sections on how to correctly configure the board. Failure to correctly
configure the board may cause irreparable component, MCU or EVB
damage.
