STMicroelectronics STM32F105VC Controller

The STM32F105xx and STM32F107xx connectivity line incorporates a high-performance ARM Cortex -M3 32-bit RISC core running at 72 MHz, along with high-speed embedded memories (Flash up to 256 Kbytes and SRAM 64 Kbytes), and a wide array of enhanced I/Os and peripherals connected to two APB buses. All devices feature two 12-bit ADCs, four general-purpose 16-bit timers plus a PWM timer, along with 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.
