General Description MDT10P721 -PortB<7:4> interrupt on change -CCP,SCM This EPROM-Based 8-bit micro-controller uses a fully static A/D converter module: CMOS technology process to achieve higher speed and -5 analog inputs multiplexed into one A/D smaller size with the low power consumption and high converter noise immunity. On chip memory includes 4K words of -8-bit resolution ROM, and 192 bytes of static RAM. TMR0 : 8-bit real time clock/counter TMR1 : 16-bit real time clock/count 2. Features TMR2 : 8-bit clock/counter(internal) 4 types of oscillator can be selected by The followings are some of the features on the hardware programming option: and software : RC－Low cost RC oscillator Fully CMOS static design LFXT－Low frequency crystal oscillator 8-bit data bus XTAL－Standard crystal oscillator On chip EPROM size : 4.0 K words HFXT－High frequency crystal oscillator Internal RAM size : 224 bytes On-chip RC oscillator based Watchdog (192 general purpose registers, 32 special Timer(WDT) registers) 22 I/O pins with their own independent direction 37 single word instructions control 14-bit instructions 8-level stacks 3. Applications Operating voltage : 2.5 V ~ 5.5V (PRD Disable) 4.5 V ~ 5.5 V (PRD Enable) The application areas of this MDT10P721 range from Operating frequency : DC ~ 20 MHz appliance motor control and high speed auto-motive to The most fast execution time is 200 ns under 20 low MHz in all single cycle instructions except the devices, and telecommunications processors, such as branch instruction Remote controller, small instruments, chargers, toy, Addressing modes include direct, indirect and automobile and PC peripheral … etc. power remote transmitters/receivers, relative addressing modes Power-on Reset Power edge-detector Reset Power range-detector Reset Sleep Mode for power saving Capture,Compare,PWM module Synchronous serial port with SCM 8 interrupt sources: -External INT pin -TMR0 timer,TMR1 timer,TMR2 timer -A/D conversion completion This specification are subject to be changed without notice.
