General Description u This EPROM-Based 8-bit micro-controller uses a fully -Four analog inputs multiplexed into one A/D static CMOS technology process to achieve higher speed and smaller size with the low converter power consump-tion and high noise immunity. On chip A/D converter module: -8-bit resolution u 4 types of oscillator can be selected by memory incl-udes 1K words of ROM, and 68 bytes of programming option: static RAM. RC－Low cost RC oscillator LFXT－Low frequency crystal oscillator 2. Features XTAL－Standard crystal oscillator HFXT－High frequency crystal oscillator The followings are some of the features on the u hardware and software : 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler u Fully CMOS static design u 8-bit data bus u On chip EPROM size : 1.0 K words u Internal RAM size : 84 bytes u On-chip RC oscillator based Watchdog Timer(WDT) u 13 I/O pins with their own independent direction control (68 general purpose registers, 16 special registers) 3. Applications u 37 single word instructions u 14-bit instructions The application areas of this MDT2051 range from u 8-level stacks appliance motor control and high speed automotive u Operating voltage : 2.5 V ~ 5.5 V (PRD Disable) to low power remote transmitters/receivers, pointing 4.5 V ~ 5.5 V (PRD Enable) devices, and telecommunications processors, such u Operating frequency : DC ~ 20 MHz as Remote controller, small instruments, chargers, u The most fast execution time is 200 ns under toy, automobile and PC peripheral … etc. 20 MHz in all single cycle instructions except the branch instruction u Addressing modes include direct, indirect and relative addressing modes u Power-on Reset u Power edge-detector Reset u Power range-detector Reset u Sleep Mode for power saving u Four interrupt sources: -External INT pin -TMR0 timer -A/D conversion completion -PortB<7:4> interrupt on change This specification are subject to be changed without notice.
