Instructions for Using the UPD78F0123H

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 2.4V to 5.5V.
    • The typical supply current (ICC) is 2.5mA.
  2. Oscillator Configuration:

    • The oscillator frequency (fosc) can be set between 1.0MHz and 20.0MHz.
    • Use an external crystal or ceramic resonator for accurate frequency generation.
  3. Temperature Range:

    • The operating temperature (Ta) should be between -40°C and 85°C.
  4. Input and Output Levels:

    • Input high voltage (VIH) should be at least 2.0V and up to 5.5V.
    • Input low voltage (VIL) should be between 0.0V and 0.8V.
    • Output high voltage (VOH) will be between 2.4V and 5.0V.
    • Output low voltage (VOL) will be between 0.0V and 0.4V.
  5. Output Current:

    • The output high current (IOH) can source up to 20mA.
    • The output low current (IOL) can sink up to 20mA.
  6. Timing Parameters:

    • Propagation delay time (tpd) is typically 100ns.
    • Rise time (tris) and fall time (tfall) are typically 10ns each.
  7. Programming and Debugging:

    • Use an appropriate programmer or debugger to load and test your firmware.
    • Refer to the datasheet for specific programming and debugging interfaces.
  8. Handling and Storage:

    • Handle the device with care to avoid static damage.
    • Store in a dry, cool place away from direct sunlight.
  9. Pin Configuration:

    • Refer to the pin configuration diagram in the datasheet for correct connections.
    • Ensure all necessary decoupling capacitors are placed close to the power pins.
  10. Application Notes:

    • Consult the application notes for specific use cases and advanced features.
    • For detailed information on power-up sequences, reset conditions, and other operational details, refer to the datasheet.
