STM32F358xC

Functional overview

3.20

Universal synchronous/asynchronous receiver transmitter

(USART)

The STM32F358xC devices have three embedded universal synchronous/asynchronous

receiver transmitters (USART1, USART2 and USART3).

The USART interfaces are able to communicate at speeds of up to 9 Mbits/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 and have LIN Master/Slave capability. The USART interfaces can be

served by the DMA controller.

3.21

Universal asynchronous receiver transmitter (UART)

The STM32F358xC devices have 2 embedded universal asynchronous receiver

transmitters (UART4, and UART5). The UART interfaces support IrDA SIR ENDEC,

multiprocessor communication mode and single-wire half-duplex communication mode. The

UART4 interface can be served by the DMA controller.

Refer to Table 8 for the features available in all U(S)ARTs interfaces.

3.22

Serial peripheral interface (SPI)/Inter-integrated sound

interfaces (I2S)

Up to three 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.
