    Note:1. Part number which include a "U" have an internal UART function; part numbers which include a "B" have a USB interface.
    2. All devices include a fully integrated RC system oscillator.
    3. For I/O lines on each device can be configured as software LCD COM driver pins.
    4. "*" As not all package types are available for the HT68FUx0 and HT68FBx0 devices, consult the datasheet for exact package details.

    Note:1. Part number which include a "U" have an internal UART function; part numbers which include a "B" have a USB interface.
    2. All devices include a fully integrated RC system oscillator.
    3. Four I/O lines on each device can be configured as software LCD COM driver pins.
    4. "*" As not all package types are available for the HT66FUx0 and HT66FBx0 devices, consult the datasheet for exact package details.
