Introduction

3 Introduction

This evaluation board allows the user to implement the functionality of the MC33903 product System

Basis Chip (SBC).

This EVB includes one I/O test point that can be configured to be pulled up to VSUP or pulled down to

GND through a resistor and indicator LED. It is easily configured via jumper settings. The SBC can also

be exercised in debug mode (watchdog re-fresh/monitoring not needed) by simply populating a jumper.

Specified resistor pull-downs can be implemented on the DBG and MUX pins via simple jumper

configurations. The status of I/O0, 5V_CAN, SAFE, and VDD can be visually monitored via on-board

LEDs. The CAN and LIN Bus signals are provided through terminal block connectors.

An isolated terminal block connector is implemented to provide power to the evaluation board with an

external DC power supply.

The evaluation boards are operated through the graphical user interface (GUI) paired up with the SPI

dongle board (KITUSBSPIDGLEVME) through the 2x8 pin ribbon cable. Additionally, for added flexibility,

the user can implement a custom board with a microcontroller to talk to the SBC via the 16 pin header.

Hardware Configuration

6 Hardware Configuration

The KIT33903BD5EVBE/KIT33903BD3EVBE operates with a single 5.5 V minimum power supply and

can be driven with the KITUSBSPIDGLEVME along with its GUI. For added flexibility, it is also possible

to develop a custom board to drive this evaluation board via the 16 pin standard header.

6.1 Board Implementation

For Standard EVB configuration, set up the jumpers as shown on Figure 3. If the jumper configuration is

in accordance with Jumper Connections, on page 8, the VDD (D3) and the 5V_CAN (D4) LEDs must be

ON at startup. If CAN communication will be exercised, populate the CAN termination socket (J13) with

the necessary components to implement the chosen CAN Termination as shown on Figure 4.
