Getting to Know the Hardware

3.1

Board Overview

The KITVALVECNTLEVM Evaluation Board facilitates the development of hydraulic and pneumatic systems that use either the SB0800

Octal Valves Controller SoC or the SB0410 Quad Valves Controller SoC. The EVB allows designers to evaluate the MC34SB0800 and

the MC34SB0410 separately or in unison. Designers monitor and control, through the MCU, the Valve Controller SoC functions using a

downloadable Windows-based Graphical User Interface (GUI.) The KITVALVECNTLEVM communicates with the PC through an on-board

FTDI to USB port. The board comes preloaded with firmware, but users can download their own firmware using a program connector

provided on the board. (Use the S12 Multilink Programmer/Debugger to perform the programming.) The board also contains an SPI

connector that allows direct access to the MC34SB0800 and MC34SB0410 SPI pins.

Board Features

The board features are as follows:

• Support for both MC34SB0800 and MC34SB0410 (either separately or in unison)

• SPI port providing direct access to MCU SPI pins

• CAN and LIN bus connectors
