STM32F303CBT7

The STM32F303CBT7 is a 32-bit 128kB flash ARM®Cortex® -M4 Microcontroller Unit offers digital signal processing (DSP) and floating point unit (FPU). It offers up to four fast 12-bit ADCs, seven comparators and four operational amplifiers, up to two DAC channels, a low-power RTC and up to five general-purpose 16-bit timers, one general-purpose 32-bit timer and two timers dedicated to motor control. It also features standard and advanced communication interfaces up to two I²Cs, up to three SPIs and three USARTs, up to two UARTs, CAN and USB. To achieve audio class accuracy, the I²S peripherals can be clocked via an external PLL. It incorporates high-speed embedded memories and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
