General Description This EPROM-Based 8-bit micro-controller uses a fully static CMOS design technology combines higher speeds and smaller size with the low power and high noise immunity. On chip memory system includes 1.0 K words of ROM, and 32 bytes of static RAM. 2. Features The followings are some of the features on the hardware and software : Fully CMOS static design 8-bit data bus On chip ROM size : 1K words Internal RAM size : 32 bytes (25 general purpose registers, 7 special registers) 36 single word instructions 14-bit instructions 2-level stacks Operating voltage : 2.3V ~ 6.0 V Operating frequency : 0 ~ 20 MHz The most fast execution time is 200 ns under 20 MHz in all single cycle instructions except the branch instructions Addressing modes include direct, indirect and relative addressing modes Power-on Reset (POR), only available MDT10P10(BG) with 8-bit programmable prescaler 4 types of oscillator can be selected by programming option (Internal Capacitor about 10p ): RC－Low cost RC oscillator LFXT－Low frequency crystal oscillator XTAL－Standard crystal oscillator HFXT－High frequency crystal oscillator 4 oscillator start-up time can be selected by programming option: 150 µs, 20 ms, 40 ms, 80 ms On-chip RC oscillator based Watchdog Timer(WDT) can be operated freely 12 I/O pins with their own independent direction control 3. Applications The application areas of this MDT10P10 range from appliance motor control and high speed automotive to low power remote transmitters/receivers, pointing devices, and telecommunications processors, such as Remote controller, small instruments, chargers, toy, automobile and PC peripheral … etc. while PED is Disable Power edge-detector Reset (PED) Sleep Mode for power saving 8-bit real time clock/counter(RTCC) This specification are subject to be changed without notice.
