STM32F410x8/B Functional overview

3.23 Serial peripheral interface (SPI)
The devices feature three SPIs in slave and master modes in full-duplex and simplex
communication modes. SPI1 and SPI5 can communicate at up to 50 Mbit/s, SPI2 can
communicate at up to 25 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.
3.24 Inter-integrated sound (I
2
S)
Three standard I
2
S interfaces (multiplexed with SPI1 to SPI5) are available. They can be
operated in master or slave mode, in simplex communication modes and can be configured
to operate with a 16-/32-bit resolution as an input or output channel. All the I2Sx audio
sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of the
I
2
S interfaces is/are configured in master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency.
All I
2
Sx can be served by the DMA controller.
3.25 Random number generator (RNG)
All devices embed an RNG that delivers 32-bit random numbers generated by an integrated
analog circuit.
