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.

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

2.1 mm barrel connector – P28:

2-way lever connector – P32:

Figure 5. 2-lever power connector

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.
