MDT1051 Datasheet | Micon Design Technology

Description u 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 A/D converter module: -Four analog inputs multiplexed into one A/D converter -8-bit resolution 4 types of oscillator can be selected by programming option: RC¡ÐLow cost RC oscillator LFXT¡ÐLow frequency crystal oscillator .. consump-tion and high noise immunity. On chip memory incl-udes 1K words of ROM, and 68 bytes of static RAM. 2. Features 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 : 84 bytes (68 general purpose registers, 16 special registers) u u u u 37 single word instructions 14-bit instructions 8-level stacks Operating voltage : 2.5 V ~ 5.5 V (PRD Disable) 4.5 V ~ 5.5 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 Four interrupt sources: -External INT pin -TMR0 timer -A/D conversion pletion -Port B<7:4> interrupt on change u u u 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) 13 I/O pins with their own independent direction control 3. Applications The application areas of this MDT1051 range from appliance motor control and high speed automotive to low power remote transmitters/receivers, pointing devices, and telemunications processors, such as Remote controller, small instruments, chargers, toy, automobile and PC peripheral … etc. This specification are subject to be changed without notice.
