What peripherals are the most required in Embedded systems?

We are designing a new board and I was not sure what peripherals we should bring out. You helped me to answer some important questions in our survey. In return, I am going to share the results with you. Some are quite interesting. Thank you!

Until today, we have received 37 responses. In the graphs, the column with BOLD text shows how many people voted for that answer.
