Universal synchronous/asynchronous receiver transmitters

(USART)

The device embeds up to two universal synchronous/asynchronous receiver transmitters

(USART1 and USART2), which communicate at speeds of up to 6 Mbit/s.

They provide hardware management of the CTS and RTS signals, multiprocessor

communication mode, master synchronous communication and single-wire half-duplex

communication mode. The USART1 supports also auto baud rate feature.

The USART interfaces can be served by the DMA controller.

Refer to Table 8 for the differences between USART1 and USART2.

Serial peripheral interface (SPI)

Up to two SPIs are able to communicate up to 18 Mbits/s in slave and master modes in full-

duplex and half-duplex communication modes. The 3-bit prescaler gives 8 master mode

frequencies and the frame size is configurable from 4 bits to 16 bits.

Refer to Table 9 for the differences between SPI1 and SPI2.
