Functional overview
STM32F070CB/RB/C6/F6
22/83
DocID027114 Rev 3
Table 7 gives an overview of features as implemented on the available USART interfaces.
All USART interfaces can be served by the DMA controller.
3.15
Serial peripheral interface (SPI)
Up to two SPIs are able to communicate up to 18 Mbit/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.
SPI1 and SPI2 are identical and implement the set of features shown in the following table.
