INTRODUCTION

TheHoltHI‐3593ARINC429EvaluationBoardcanbeusedtoevaluatemostofthefeaturesoftheHI‐
3593ARINCDualReceiverandSingleTransmitterIC.TheHI‐3593featuresanon‐chipDC‐DCconverter
whichgeneratesboth+5Vand‐5Vtosupplythebipolardifferentialvoltagelevelsneededtomeetthe
ARINC429Buslevelsfromasingle3.3Vsupplyvoltage.Themainboard“GeneralPurposeSPI
EvaluationBoard”includesswitches,pushbuttonswitchesandLEDstohelpnavigatetheoperating
modesandconfirmdataandstatusinformation.AFreescaleMC9S12XDT512microcontrolleronthe
mainboardcommunicateswiththeHI‐3593throughtheSPIinterface.ASerialUARTportisprovided
whichenablesviewingmessagesandstatusinformationorenteringofoptionalcommandsusingany
terminalprogramsuchasHyper‐Terminal.TheHI‐3593EvaluationBoardisadaughtercardthatplugson
