MD6602 Series is an 8bit MCU (Micro Controller Unit) which is suitable for Power Control Application such as Digital Power Supply. It contains Rich Analog Functions, High Performance DSP (Digital Signal Processor), and High Resolution PWM, which can make your application much more efficient and much higher performance depending on the MCU’s low power consumption and forcible system support functionality.


    ・Rich analog functions
    Interconnections among Analog Components and External Pins are configurable by programmable analog network. A/D Converters, Comparators, and General Purpose OPAMPs are included.
    ・High Performance DSP Operations
    In addition to 8bit CPU, dedicated two 16bit TinyDSPs are integrated, which ensure Parallel Processing,
    ・DMA capability between Peripherals (DSAC)
    Data Transfers between Peripheral can be triggered by internal events. It can make Automatic Feedback Control System by communicating among A/D converter, TinyDSPand PWM without CPU interposition.
    ・System Support
    FLASH Memory, Timer Functionality, Serial Communications, Internal Oscillator, Power On Reset Circuit are also integrated.


    ・DC/DC power supply
    ・AC/DC power supply
    ・LED lighting control
    ・LED signage
    ・Motor control
    ・Chargers ...and so forth
