MDT10P61
1. General Description
This EPROM-Based 8-bit micro-controller uses a fully static CMOS technology process to achieve higher speed and smaller size with the low power u 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
consump-tion and high noise immunity. On chip memory incl-udes 1K words of ROM, and 68 b tes of y static RAM.
2. Features
The followings are some of the features on the hardware and software : u u u u Fully COMS static design 8-bit data bus On chip EPROM size : 1.0 K words Internal RAM size : 81 bytes (68 general purpose registers, 13 special registers) u u u u 37 single word instructions 14-bit instructions 8-level stacks Operating voltage : 2.5 V ~ 6.5 V (PRD Disable) 4.5 V ~ 6.5 V (PRD Enable) u u 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 u Power-on Reset Power edge-detector Reset Power range-detector Reset Sleep Mode for power saving 3 interrupt sources: -External INT pin -TMR0 timer -PortB interrupt on change
