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