STM32F105RCT7

The clock, reset, and supply management features of the STM32F105xx and STM32F107xx MCUs include: - Application supply and I/Os ranging from 2.0 to 3.6 V . - Power-on reset (POR), power-down reset (PDR), and programmable voltage detector (PVD) . - Support for a 3-to-25 MHz crystal oscillator . - Internal 8 MHz factory-trimmed RC oscillator . - Internal 40 kHz RC oscillator with calibration . - 32 kHz oscillator for Real-Time Clock (RTC) with calibration . These features contribute to the efficient operation and management of the MCU's clock, reset, and power supply requirements. .

The STM32F105xx and STM32F107xx microcontroller units have a total of five communication interfaces available. These include three universal synchronous/asynchronous receiver transmitters (USART1, USART2, and USART3) and two universal asynchronous receiver transmitters (UART4 and UART5) .

The maximum frequency of the ARM 32-bit Cortex-M3 CPU in the STM32F105xx and STM32F107xx MCUs is 72 MHz.
