MDT2030

MDT2030 1. General Description This ROM-Based 8-bit micro-controller uses a fully static CMOS technology process to achieve high speed, small size, the low power and high noise immunity. On chip memory includes 2K words EPROM, and 80 bytes static RAM. u u u u 4 oscillator start-up time can be selected by programming option: 150 µs, 20 ms, 40 ms, 80 ms 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler On-chip RC oscillator based Watchdog Timer(WDT) 12 I/O pins with their own independent direction control 2. Features 3. Applications The followings are some of the features on the hardware and software : u u u u Fully CMOS static design 8-bit data bus On chip EPROM size : 2.0 K words Internal RAM size : 80 bytes (73 general purpose registers, 7 special registers) u u u u u u 36 single word instructions 14-bit instructions 2-level stacks Operating voltage : 2.3 V ~ 5.5 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 instruction u Addressing modes include direct, indirect and relative addressing modes u u u u Power-on Reset Power edge-detector Reset Sleep Mode for power saving 4 types of oscillator can be selected by programming option: RC¡ÐLow cost RC oscillator LFXT¡ÐLow frequency crystal oscillator XTAL¡ÐStandard crystal oscillator HFXT¡ÐHigh frequency crystal oscillator This specification are subject to be changed without notice.
