The device embeds 256 Kbytes of Flash memory and 40 Kbytes of SRAM with hardware parity check on the first 16 Kbytes. The STM32F302RCT6 integrates a rich set of analog peripherals including two fast 12-bit ADCs (5 Msps) with selectable resolution of 12\/10\/8\/6 bits and differential input capability, one 12-bit DAC channel, four rail-to-rail analog comparators, and two operational amplifiers that can be configured in programmable gain amplifier (PGA) mode with all terminals accessible. The advanced-control timer with complementary PWM outputs, dead-time generation, and emergency stop makes this device particularly well-suited for motor control applications. Communication interfaces include CAN 2.0B Active, USB 2.0 full-speed, up to three SPIs (two with I2S), two I2C Fast Mode Plus, and up to five USART\/UARTs.","working_principle":"The STM32F302RCT6 operates as a 32-bit ARM Cortex-M4 microcontroller with integrated mixed-signal peripherals. The Cortex-M4 core with FPU supports single-precision floating-point operations compliant with IEEE 754, enabling efficient DSP algorithm implementation. The dual ADCs use a switched-capacitor successive approximation architecture sampling at up to 5 Msps. The comparators provide rail-to-rail input with programmable hysteresis and output filtering. The op-amps can be internally connected to ADC inputs and DAC outputs in PGA mode, enabling analog signal conditioning without external components. The TIM1 advanced motor control timer generates up to 6 complementary PWM channels with programmable dead-time and break inputs for emergency shutdown.","pin_description":"
