STMicroelectronics provides a comprehensive portfolio of robust 8-bit microcontrollers and high-performance 32-bit ARM-based microcontrollers with a wide range of peripherals.  Extensive support through a combination of flexible and powerful development tools, training courses, consultancy and web support facilitate faster time to market.

The STM32F105xx and STM32F107xx connectivity line family incorporates the highperformance ARM® Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 256 Kbytes and SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, four general-purpose 16-bit timers plus a PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2Ss, five USARTs, an USB OTG FS and two CANs. Ethernet is available on the STM32F107xx
only.

The STM32F105xx and STM32F107xx connectivity line family operates in the –40 to +105 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of powersaving mode allows the design of low-power applications.  Connectivity line devices are available in three different package types: from 64 pins to 100 pins.
