coupled with excellent noise immunity and ESD protection ensure that reliable operation is

maintainedinhostileelectricalenvironments.

AfullchoiceofHXT,LXT,ERC,HIRCandLIRCoscillatorfunctionsareprovidedincludinga

fullyintegratedsystemoscillatorwhichrequiresnoexternalcomponentsforitsimplementation.

Theabilitytooperateandswitchdynamicallybetweenarangeofoperatingmodesusingdifferent

clocksourcesgivesuserstheabilitytooptimisemicrocontrolleroperationandminimisepower

consumption.

TheUARTmoduleiscontainedintheHT68FUx0seriesofdevices.Itcansupporttheapplications

suchasdatacommunicationnetworksbetweenmicrocontrollers,low-costdatalinksbetweenPCs

andperipheraldevices,portableandbatteryoperateddevicecommunication,etc.

TheinclusionofexibleI/Oprogrammingfeatures,Time-Basefunctionsalongwithmanyother

featuresensurethatthedeviceswillndexcellentuseinapplicationssuchaselectronicmetering,
