HT66F0175/HT66F0185
A/D Flash MCU with EEPROM
General Description
TheseriesofdevicesareFlashMemoryA/Dtype8-bithighperformanceRISCarchitecture
microcontroller.OfferinguserstheconvenienceofFlashMemorymulti-programmingfeatures,
thesedevicesalsoincludeawiderangeoffunctionsandfeatures.Othermemoryincludesanarea
ofRAMDataMemoryaswellasanareaoftrueEEPROMmemoryforstorageofnon-volatiledata
suchasserialnumbers,calibratuibdata,etc.
Analogfeaturesincludeamulti-channel12-bitA/Dconverterandacomparatorfunctions.Multiple
andextremelyflexibleTimerModulesprovidetiming,pulsegenerationandPWMgeneration
functions.ProtectivefeaturessuchasaninternalWatchdogTimer,LowVoltageResetandLow
VoltageDetectorcoupledwithexcellentnoiseimmunityandESDprotectionensurethatreliable
operationismaintainedinhostileelectricalenvironments.AfullchoiceofHXT,LXT,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minimizepowerconsumption.
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,
environmentalmonitoring,handheldinstruments,householdappliances,electronicallycontrolled
tools,motordrivinginadditiontomanyothers.
