The microcontollercore is an optimized 8051 core that executes up to three times faster than the standard 8051core, given the same clock source. This makes it possible to run the device at a lower externalclock frequency and achieve the same performance at lower power than the standard 8051core. The MSC1201Yx/MSC1202Yx are designed for high-resolution measurement applications.AIN0AIN1AIN2AIN3AIN4AIN5AINCOMIDACAVDDAVDD AGNDMUXAGNDBurnoutDetectBUFBurnoutDetectTemperatureSensor8-Bit IDACMSC1201 functional block diagram.PGAREFOUT/REFIN+ REFIN– DVDD DGNDV REF8-BitOffset DACModulator4kB or 8kBFLASH256 BytesSRAMPORALVDDBORDigitalFilterACC8051SFRSystemClockDividerMSC1201Timers/CountersWDTPORT1PORT3On-ChipOscillatorXINPLLXOUTALTERNATEFUNCTIONSDINDOUTSSEXTPROGRSTUSARTEXTT0T1SCK/SCL/CLKS8051-Based Intelligent ∆Σ MicroSystems Selection GuideADC Sample Number of Input Program DACRes.
