1. I = input, O = output, S = supply.

2. FT = 5 V tolerant.

3. Function availability depends on the chosen device. For devices having reduced peripheral counts, it is always the lower

number of peripheral that is included. For example, if a device has only one SPI and two USARTs, they will be called SPI1

and USART1 & USART2, respectively. Refer to Table 1 on page 10.
