MC81F4204April 24, 2012 Ver.1.41 9MC81F42048 bit MCU with 12-bit A/D Converter1. OVERVIEW1.1 DescriptionMC81F4204 is a CMOS 8 bit MCU which provides a 4K bytes FLASH-ROM and 192 bytes RAM.It has following major features,12 bit ADC : It has 10 ch A/D Converter which can be used to measure minute electronic voltage andcurrents.810 Core : Same with ABOV’s 800 Core but twice faster. 800 Core use a divided system clock but810 Core use a system clock directly1.2 FeaturesROM (FLASH) : 4K Bytes(Endurance: 100 cycle)SRAM :192 BytesMinimum instruction execution time166n sec at 12MHz (NOP instruction)12-bit A/D converter : 10 chGeneral Purpose I/O (GPIO)20-pin PKG: 1816-pin PKG: 14Timer/counter8Bit x 3chSIO : 1chPWM8Bit x 2ch10Bit x 2ch (High Speed PWM)Basic Interval Timer (BIT) : 8Bit x 1chOne Watchdog timer (WDT) : 8Bit x 1chBuzzer : 1ch244 ~ 250kHz @8MHzPower On Reset(POR)Low Voltage Reset (LVR)4 level detector (2.4/2.7/3.0/4.0V)Interrupt sources : 21chExternal Interrupt : 12chTimer : 8chSIO : 1chPower Down ModeStop modeSleep modeOperating Voltage & Frequency2.2V – 5.5V (at 1.0 – 4.2MHz)2.7V – 5.5V (at 1.0 – 8.0MHz)4.0V – 5.5V (at 1.0 – 12.0MHz)Operating Temperature- 40°C ~ 85°COscillator TypeCrystal, Ceramic, RC for main clockInternal Oscillator(8MHz/4MHz/2MHz/1MHz)Package20PDIP, 20SOP, 20TSSOP16PDIP, 16SOP, 16TSSOPAvailable Pb free package
