Universal synchronous/asynchronous receiver transmitter
(USART)
The STM32F37x embeds three universal synchronous/asynchronous receiver transmitters
(USART1, USART2 and USART3).
All USARTs interfaces are able to communicate at speeds of up to 9 Mbit/s.
They provide hardware management of the CTS and RTS signals, they support IrDA SIR
ENDEC, the multiprocessor communication mode, the single-wire half-duplex
communication mode, Smart Card mode (ISO 7816 compliant), autobaudrate feature and
have LIN Master/Slave capability. The USART interfaces can be served by the DMA
controller.

interfaces (I
Up to three SPIs are able to communicate at 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 is configurable to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes.
The SPIs can be served by the DMA controller.
Three standard I
be operated in master or slave mode. These interfaces can be configured to operate with
16/32 bit resolution, as input or output channels. Audio sampling frequencies from 8 kHz up
to 192 kHz are supported. When either or both of the I
