Note: As devices exist in more than one package format, the table reflects the situation for the package with the
most pins.
There is an additional peripheral known as the UART module in HT68FU30, HT68FU40, HT68FU50 and
HT68FU60 devices. All information related to the UART Module will be described in the following UART
Module section.
