Introduction
MPC5777C EVB User Guide, Rev. 1
1.1 Modular Concept
For maximum flexibility and simplicity, the EVB has been designed as a modular development platform.
The EVB main board does not contain an MCU. Instead, the MCU is fitted to an MCU daughter card
(occasionally referred to as an adapter board). This approach means that the same EVB platform can be
used for multiple packages and MCU derivatives within the MPC57xx family. High density connectors
provide the interface between the EVB and MCU daughter cards as shown Figure 1 See Section 4&5, “
Configuration —MPC5777C-516DS Daughter card”for more details on the daughter cards and Section
6, “Board Interface Connector”for more details on the interface connectors.
Figure 1: Modular concept –Mother Board (MB) and MCU daughter card
Please consult the MPC57xx website at www.nxp.com or speak to your NXP representative for more
details on the availability of MCU daughter cards.
The EVB is designed to be used with the motherboard and standalone configurations
NOTE
For details on your specific daughter card, please consult the instructions
included with the daughter card.
1.2 Daughter Card Availability
A number of compatible daughter cards are available for the motherboard across a number of devices.

EVB Features
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.
3. Configuration —Motherboard
This section details the configuration of each of the Mother Board functional blocks.

The Mother Board has been designed with ease of use in mind and has been segmented into functional
blocks as shown in Figure 2 Detailed silkscreen legend has been used throughout the board to identify
all switches, jumpers and user connectors.
Figure 2: Mother Board - Functional Blocks
3.1 Power Supply Configuration
The EVB requires an external power supply voltage of 12 V DC, minimum 1 A. This allows the EVB
to be easily used in a vehicle if required. The single input voltage is regulated on-board using three
switching regulators to provide the necessary EVB and MCU operating voltages of 5.0 V, 3.3 V, 1.25 V
and one 5 V linear regulator for the ADC supplies and references.
For flexibility there are two different power supply input connectors on the motherboard as detailed
below. There is also a power supply option on the daughter card to use the daughter card in standalone
mode. Please refer to Section 4.1.2, 4.1.3 “Daughter Card Standalone Power Input -External &
Daughter Card Standalone Power Input –Power SBC” for details on the daughter card power input.

This can be used to connect a bare wire lead to the EVB, typically from a laboratory power supply.
The polarization of the connectors is clearly marked on the EVB. Care must be taken to ensure correct
connection.

3.1.2Regulator Power Jumpers
There are four power regulator circuits on the MPC57xx motherboard that supply the required voltages
to operate the MCUs:
• 5V_SR: 5 V switching regulator to supply the power management controller, I/O and peripherals
• 3.3V_SR: 3.3 V switching regulator for Ethernet, debug and I/O
• 5V_LR: 5 V linear regulator for ADC supply and reference
All of the regulators have the option of being disabled/ enabled if they are not required. By default
(jumpers are off), all of the switching regulators are enabled and the 5 V linear regulator is disabled. The
regulators can be enabled individually by the following jumper settings:
• Connecting J57 enables the 5 V linear regulator
• Disconnecting J58 enables the 5 V switching regulator
• Disconnecting J59 enables the 3.3 V switching regulator
• Disconnecting J60 enables the 1.25 V switching regulator
The regulators supply power to the daughter cards through the board connector. The individual
selection and configuration of the MCU supplies are done on the daughter cards.

NOTE
Not all the supported daughter card MCUs require all the supplies to be
switchedon.Pleaserefer toSection 4 “Configuration — MPC5777C-
416DS Daughter card” for details.
3.1.3Power Switch, Status LEDs and Fuse
The main power switch (slide switch SW5) can be used to isolate the power supply input from the EVB
Voltage regulators if required.
• Moving the slide switch to the right (away from connector P33) will turn the EVB on
• Moving the slide switch to the left (towards connector P33) will turn the EVB off
When power is applied to the EVB, four green power LEDs adjacent to the voltage regulators show
the presence of the supply voltages as follows:
• LED D9 –Indicates that the 5.0 V linear regulator is enabled and working correctly
• LED D11 –Indicates that the 5.0 V switching regulator is enabled and working correctly
• LED D12 –Indicates that the 3.3 V switching regulator is enabled and working correctly
• LED D13 –Indicates that the 1.25 V switching regulator is enabled and working correctly
If no LED is illuminated when power is applied to the EVB and the regulators are correctly enabled
using the appropriate jumpers, it is possible that either power switch SW5 is in the “OFF” position or
that the fuse F1 has blown. The fuse will blow if power is applied to the EVB in reverse-bias, where a
protection diode ensures that the main fuse blows rather than causing damage to the EVB circuitry. If
the fuse has blown, check the bias of your power supply connection then replace fuse F1 with a 20mm
1.5A fast blow fuse.
3.2 CAN Configuration
The EVB has two NXP TJA1041T high speed CAN transceivers and two standard DB9 connectors
to provide physical CAN interfaces for the MCU.
The pinout of the DB9 connectors (J5/J6) is shown in Figure 5.

3.4 LIN Configuration
The EVB is fitted with a NXP MC33662LEF LIN transceiver (U50) and two different style connectors:
A standard LIN Molex connector (J4) at the edge of the board and a standard 0.1 in. connector (P3).
The pin-out of the Molex connector J4 is shown in Figure 8.

Figure 8: LIN Molex connector
For flexibility, the LIN transceiver is also connected to a standard 0.1 in. connector (P3) at the top side
of the PCB as shown in Figure 9. For ease of use, the 12 V EVB supply is fed to pin1 of P3 and the
LIN transceiver power input to pin2. This allows the LIN transceiver to be powered directly from the
EVB supply by simply linking pins 1 and 2 of connector P3 using a 0.1 in. jumper shunt.

3.6 User Area
There is a rectangular prototype area on the EVB top right corner, consisting of a 0.1in. pitch array of
through-hole plated pads. Power from all the three switching regulators is readily accessible along
with GND through JP1 –JP16 next to the prototyping area. This area is ideal for the addition of any
custom circuitry.
