Description
STM32F205xx, STM32F207xx
28/163
Doc ID 15818 Rev 7
2.2.28
Serial peripheral interface (SPI)
The STM32F20x feature up to three SPIs in slave and master modes in full-duplex and
simplex communication modes. SPI1 can communicate at up to 30 Mbits/s, SPI2 and SPI3
can communicate at up to 15 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.
2.2.29
Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be
operated in master or slave mode, and can be configured to operate with a 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 I2S interfaces is/are configured in master
mode, the master clock can be output to the external DAC/CODEC at 256 times the
sampling frequency.
