MDT10C61 1. General Description This ROM-Based 8-bit micro-controller uses a fully static CMOS technology process to achieve higher speed and smaller size with the low power u u LFXT¡ÐLow frequency crystal oscillator XTAL¡ÐStandard crystal oscillator HFXT¡ÐHigh frequency crystal oscillator 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler On-chip RC oscillator based Watchdog Timer(WDT) u 13 I/O pins with their own independent direction control www.DataSheet4U.com consump-tion and high noise immunity. On chip memory incl-udes 1K words of ROM, and 68 bytes of static RAM. 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 ROM size : 1.0 K words Internal RAM size : 81 bytes (68 general purpose registers, 13 special registers) u u u u u u 37 single word instructions 14-bit instructions 8-level stacks Operating voltage : 2.5 V ~ 5.5 V Operating frequency : DC ~ 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 3 interrupt sources: -External INT pin -TMR0 timer -PortB<7:4> interrupt on change u 4 types of oscillator can be selected by programming option: RC¡ÐLow cost RC oscillator This specification are subject to be changed without notice....
