Functional overview
STM32F479xx
40/217
DocID028010 Rev 3
USART1, USART2, USART3 and USART6 also provide hardware management of the CTS
and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication
capability. All interfaces can be served by the DMA controller.
2.27
Serial peripheral interface (SPI)
The devices feature up to six SPIs in slave and master modes in full-duplex and simplex
communication modes. SPI1, SPI4, SPI5, and SPI6 can communicate at up to 45 Mbits/s,
SPI2 and SPI3 can communicate at up to 22.5 Mbit/s. 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. All SPIs can be served by the
DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
