STMicroelectronics STM32F105/107 processors with Cortex M3 core have speeds up to 72 MHz. The STM32 series consists of ARM based 32bit MCUs with 16-bit timers, CANs, ADCs, USB 2.0 full speed interface/OTG, Ethernet MAC and comm interface(I²C,SPI,UART). The STM32 ARM Cortex-M3 32 bit Flash microcontroller operates low voltage, low power with real time capabilities. The MCU architecture has an easy to use STM32 platform offering three different packages. These embedded devices work in applications such as motor drive; printers and scanners; alarm; and Industrial applications.
