STM32 new series of the products function: http://www.siliconray.com/
STM32 interconnection model series products are divided into two types: STM32F105 and STM32F107. STM32F105 has USB OTG and CAN2.0 B interface. STM32F107 USB OTG and CAN2.0 B in based on the Ethernet interface increased 10/100 MAC module. Chip integrated Ethernet MAC support MII and RMII, therefore, realize a complete Ethernet transceiver just an external PHY chip. Use only a 25 MHz crystals to the micro controller can provide the clock frequency, including Ethernet USB OTG peripherals and interface. Micro controller can also produce a 25 MHz or 50 MHz clock output, drive external Ethernet PHY layer chip, for the customer to save one additional crystals. Audio features, new series micro controller offers two I2S audio interface, support the host and two models from the machine, which is used as an input and can be used as output, resolution for the 16 or 32 bits.
