4.2 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 SPC58xx family and the SPC57xx family. High density connectors provide the
interface between the EVB and MCU daughter cards as shown in the figure below. See Section 4.3 Daughter
card availability for more details on the daughter cards and Section 4.17 Board interface connectors for more
details on the interface connectors.
Figure 2. Modular concept - motherboard and MCU daughter card
For details on your specific daughter card, please consult the instructions included with the daughter card.
The EVB is designed to use the motherboard and the daughter in conjunction. However, it is possible to use the
daughter cards standalone.

4.4 EVB features
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 SPC58xx MCUs and SPC57xx MCUs by utilizing MCU daughter cards
• Single 12 V external power supply input with four on-board regulators providing all the necessary EVB and
MCU voltages; power supplied to the EVB via a 2.1 mm barrel style power jack or a 2-way level connector
• 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 0.1” pitch headers
• RS232/SCI physical interface and standard DB9 female connector
• FlexRAY interface
• LINFlexD interface
• CAN FD interfaces (data rates up to 5 Mbit/s), one configurable to be connected to one out of two CAN
modules, and one connected to a dedicated third CAN module
• 10/100 Mbps ethernet interface
• Variable resistor, driving between 5 V and ground
• user switches and 4 user LEDs, freely connectable
• Liberal scattering of GND test points (surface mount loops) placed throughout the EVB
The daughter cards provide the following features:
• MCU (soldered or through a socket)
• Flexible MCU clocking options allow provision of an external clock via SMA connector or 40 MHz EVB
clock oscillator circuit. Jumpers on the daughter card allow selection between these external clocks. SMA
connector on MCU-CLKOUT signal for easy access.
• User reset switch with reset status LEDs
• Standard 14-pin JTAG debug connector and 34-pin Samtec Nexus3+ connector
• 10-pin Serial Interprocessor Interface (SIPI) connector
• Liberal scattering of ground and test points (surface mount loops) placed throughout the EVB
Note: To avoid confusion between jumpers and headers, all EVB jumpers are implemented as 2 mm pitch whereas
headers are 0.1 inch (2.54 mm). This prevents inadvertently fitting a jumper to a header.
4.5 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.

4.6 Configuration
This section details the configuration of each of the EVB functional blocks.
The EVB has been designed keeping in mind the ease of use, and has been segmented into functional blocks
as shown in the figure below. A detailed silkscreen legend has been used throughout the board to identify all
switches, jumpers and user connectors.
Figure 3. EVB functional blocks
UM2740
Configuration
UM2740 - Rev 1 page 9/45

4.7 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 and 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
daughter card documents for details on power input.
4.8 Motherboard power supply connectors

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. A special care must be taken to ensure correct
connection.

UM2740 - Rev 1 page 10/45

4.9 Regulator power jumpers
There are four power regulator circuits on the SPC58xx motherboard that supply the required voltages to operate
the MCUs:
• 1.25V_SR: 1.25 V switching regulator to supply the core voltage
• 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, FlexRAY, debug and I/O
• 5V_LR: 5 V linear regulator for ADC supply and reference
All regulators have the option of being disabled/enabled if they are not required. By default (jumpers are off),
all 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 5.0 V linear regulator
• Disconnecting J58 enables the 5.0 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.
Not all the supported daughter card MCUs require all the supplies to be switched on. Please refer to the individual
daughter card user guide for details.
4.10 Power switch, status LEDs and use
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 20 mm 1.5 A fast blow fuse.

Figure 9. LIN molex connector
For flexibility, the LIN transceiver is also connected to a standard 0.1” connector (P3) at the top side of the PCB
as shown in Figure 10. LIN 4pin header interface connector. 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" jumper shunt.
