9 / 198 page  MC81F4x32 October 19, 2009 Ver.1.35 9 MC81F4x32 8 bit MCU with 12-bit A/D Converter 1. OVERVIEW 1.1 Description MC81F4x32 is a CMOS 8 bit MCU which provides a 32K bytes FLASH-ROM and 512 bytes RAM. It has following major features, 12 bit ADC : It has 15 ch A/D Converter which can be used to measure minute electronic voltage and currents. 810 Core : Same with ABOV ‟s 800 Core but twice faster. 800 Core use a divided system clock but 810 Core use a system clock directly Power Consumption – Sub Active Mode : To decrease the power consumption, It can be operated with sub clock( 32.768KHz ). 1.2 Features ROM (FLASH) : 32K Bytes (Endurance: 100 cycle) SRAM : 1K Bytes Minimum Instruction Execution Time 166nsec (@12MHz 2 Cycle NOP Instruction) Power down mode IDLE, STOP, SLEEP mode Sub-Active mode (Operates at 32.768KHz sub clock) General Purpose I/O (GPIO) 44-pin PKG : 42 ports 42-pin PKG : 40 ports 32-pin PKG : 30 ports 28-pin PKG : 26 ports SIO : 1ch Uart : 1ch IIC slave : 1ch Timer/ Counter 8Bit × 4ch (or 16Bit x 2ch) PWM (8Bit x 2ch or 16Bit x 1ch) + 10Bit × 3ch Buzzer : 1ch ( 244 ~ 250KHz @8MHz ) Watch Timer (WT) : 8Bit × 1ch Basic Interval Timer (BIT) : 8Bit × 1ch Watch Dog Timer (WDT) : 8Bit × 1ch 12 Bit A/D Converter : 15 ch Interrupt Sources : 27ch External interrupts(EXT0~11) : 12ch Timer0~3 Match/overflow : 8ch WDT, BIT, WT : 3ch SIO,UART(Tx/Rx), IIC : 4ch Power On Reset (POR) Reset release level (detect only rising) Low Voltage Reset (LVR) 4 level detector (4.0V, 3.0V, 2.7V, 2.4V) Operating Voltage & Frequency 2.2V – 5.5V : 1.0 - 4.2 MHz 2.7V – 5.5V : 1.0 - 8.0 MHz 4.0V – 5.5V : 1.0 – 12.0 MHz Operating Temperature - 40°C ~ 85°C Oscillator Type Crystal, Ceramic, RC On-Chip RC-Oscillator (8/4/2/1MHz) PKG Type 44MQFP, 42SDIP, 32SDIP/SOP, 28 SKDIP/SOP |
