MDT10P55 1. General Description This EPROM-Based 8-bit micro-controller uses a fully u Power-on Reset u Sleep Mode for power saving u 5 types of oscillator can be selected by static CMOS technology process to achieve higher programming option: speed INTRC－Internal 4 MHz RC oscillator and smaller size with the low power consump-tion and high noise immunity. On chip RC－Low cost RC oscillator memory inclu-des 1K words of ROM, and 72 bytes of LFXT－Low frequency crystal oscillator static RAM. XTAL－Standard crystal oscillator HFXT－High frequency crystal oscillator 2. Features u 3 oscillator start-up time can be selected by The followings are some of the features on the programming option: hardware and software : 20 ms, 40 ms, 80 ms u Fully COMS static design u 8-bit data bus u On chip EPROM size : 1K words u Internal RAM size : 72 bytes u 36 single word instructions u 14-bit instructions u 2-level stacks u Operating voltage : 2.5 V ~ 6.0 V u Operating frequency : 0 ~ 20 MHz The application areas of this MDT10P55 range from u The most fast execution time is 200 ns under appliance motor control and high speed automotive 20 MHz in all single cycle instructions except to low power remote transmitters/receivers, small the branch instruction instruments, chargers, toy, automobile and PC Addressing modes include direct, indirect and pe-ripheral … etc. u u 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler u On-chip RC oscillator based Watchdog Timer(WDT) u Wake-up from sleep on pin change 3.
