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 (I2S)

Three standard I2S 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

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.

All I2Sx 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.
