      Multiple Built-In Safety Functions
      ML62Q1000 series


      ML62Q1000 series System Block Diagram
      • Feature 1: Multiple peripherals
        A wide array of peripheral circuits are built-in, including numerous serial communication circuits, multifunction timers, a high accuracy analog function, and flash memory that supports background operation allows executing the program code while writing to the data flash.
      • Feature 2: Broad lineup
        The broad lineup includes several package types, from 16 to 64 pins, in program memory sizes ranging from 16KB to 64kB. Software-compatible peripheral functions are built in. The similar pin layouts enables flexible changes of package and/or program size.
      • Feature 3: Safe operation
        Some circuits are added to expand the self-test range. Also, the mcu provides functions that prevent crystal oscillation stop by pin leakages or malfunctions at power up and/or at low voltage.

      Complete dual clock system drivers low power consumption

      Complete Dual Clock System

      This system enables selection of low-speed and high-speed clocks for each CPU and peripheral circuit. For example, when the high-speed clock is selected for the CPU and timer operation, the UART is workable at low-speed clock to wait for a receive even if the high-speed needs to be stopped. This provides flexible clock management that can help reduce power consumption considerably.

      Current Control at Powerup

      Controlling the initial current at the power up and utilizing a low-speed clock as an initial clock minimizes the startup current, allows the operation with a current-limited power supply.

      • WDT test
      • Clock backup

      8 new functions have been added to the existing safety functions of 'Tough' MCUs (ML62013x series).

      Feature 3Crystal oscillator strong against leakage (Less incidence of oscillation stop ! Safe in case it's stopped !)

      Adopting a crystal oscillator circuit strong against leakage, prevents oscillator stop due to moisture adhesion. Also, the backup RC oscillator prevents system freeze even in case the oscillation happends to stop (48-pin to 100-pin products)

      Feature 4Prevents malfunctions during power up (Prevents overcurrent, FET damage, and DAC noise)

      The voltage detection reset function works at power up or at a low voltage to prevent problems caused by undefined or open output condition of ports.

      14 safety features by hardware

      One thing to pay special attention to in designing electrical home appliances is to prevent accidents in advance. Recently, microcontrollers are used for electric home appliances, and safety is secured by the function of microcontroller. Therefore, in order to avoid danger, the microcontroller itself needs a safety function to diagnose the failure of the microcontroller itself.
      The ML62Q1000 series has many safety functions as hardware.
