They also feature standard and advanced communication interfaces.Up to three I2Cs Six SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization. Four USARTs plus four UARTs An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI), Two CANs One SAI serial audio interface An SDIO/MMC interface Ethernet and camera interface LCD-TFT display controller Chrom-ART Accelerator. Advanced peripherals include an SDIO, a flexible memory control (FMC) interface, acamera interface for CMOS sensors and a cryptographic acceleration cell.The STM32F437xx and STM32F439xx devices operates in the40 to +105 temperature range from a 1.7 to 3.6 V power supply.The STM32F437xx and STM32F439xx devices offer devices in 8 packages ranging from100 pins to 216 pins.
