the devices offer three ADCs, two DACs, two ultra-low power comparators, a low-power RTC, a high-resolution timer, 12 general-purpose 16-bit timers, two PWM timers for motor control, five low-power timers, a true random number generator (RNG). The devices support four digital filters for external sigma-delta modulators (DFSDM). They also feature standard and advanced communication interfaces.
Standard peripherals
– Four I2Cs
– Four USARTs, four UARTs and one LPUART
– Six SPIs, three I2Ss in Half-duplex mode. To achieve audio class accuracy, the
I2S peripherals can be clocked by a dedicated internal audio PLL or by an external clock to allow synchronization.
– Four SAI serial audio interfaces
– One SPDIFRX interface
– One SWPMI (Single Wire Protocol Master Interface)
– Management Data Input/Output (MDIO) slaves
– Two SDMMC interfaces
– A USB OTG full-speed and a USB OTG high-speed interface with full-speed capability (with the ULPI)
– One FDCAN plus one TT-FDCAN interface
– An Ethernet interface
– Chrom-ART Accelerator
– HDMI-CEC
Advanced peripherals including
– A flexible memory control (FMC) interface
– A Quad-SPI Flash memory interface
– A camera interface for CMOS sensors
– An LCD-TFT display controller
– A JPEG hardware compressor/decompressor
