Description
The STM32F302xB/STM32F302xC family is based on the high-performance ARM® Cortex®-M4 32-bit RISC core with FPU operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU), a memory protection unit (MPU) and an embedded trace macrocell (ETM). The family incorporates high-speed embedded memories (up to 256 Kbytes of Flash memory, up to 40 Kbytes of SRAM) and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

Features
• Core: ARM® Cortex®-M4 32-bit CPU with FPU (72 MHz max), single-cycle multiplication and HW division, DSP instruction and MPU (memory protection unit)
• Operating conditions:
    – VDD, VDDA voltage range: 2.0 V to 3.6 V
• Memories
    – 128 to 256 Kbytes of Flash memory
    – Up to 40 Kbytes of SRAM, with HW parity check implemented on the first 16 Kbytes.
• CRC calculation unit
• Reset and supply management
    – Power-on/Power-down reset (POR/PDR)
    – Programmable voltage detector (PVD)
    – Low-power modes: Sleep, Stop and Standby
    – VBAT supply for RTC and backup registers
• Clock management
    – 4 to 32 MHz crystal oscillator
    – 32 kHz oscillator for RTC with calibration
    – Internal 8 MHz RC with x 16 PLL option
    – Internal 40 kHz oscillator
• Up to 87 fast I/Os
    – All mappable on external interrupt vectors
    – Several 5 V-tolerant
• Interconnect matrix

• Two ADCs 0.20 µS (up to 17 channels) with selectable resolution of 12/10/8/6 bits, 0 to 3.6 V conversion range, single ended/differential input, separate analog supply from 2 to 3.6 V
• One 12-bit DAC channel with analog supply from 2.4 to 3.6 V
• Four fast rail-to-rail analog comparators with analog supply from 2 to 3.6 V
• Two operational amplifiers that can be used in PGA mode, all terminals accessible with analog supply from 2.4 to 3.6 V
• Up to 24 capacitive sensing channels supporting touchkey, linear and rotary touch sensors
• Up to 11 timers
    – One 32-bit timer and two 16-bit timers with up to 4 IC/OC/PWM or pulse counter and quadrature (incremental) encoder input
    – One 16-bit 6-channel advanced-control timer, with up to 6 PWM channels, deadtime generation and emergency stop
    – One 16-bit timer with 2 IC/OCs, 1 OCN/PWM, deadtime generation and emergency stop
    – Two 16-bit timers with IC/OC/OCN/PWM, deadtime generation and emergency stop
    – Two watchdog timers (independent, window)
    – SysTick timer: 24-bit downcounter
    – One 16-bit basic timer to drive the DAC
• Calendar RTC with Alarm, periodic wakeup from Stop/Standby
• Communication interfaces
    – CAN interface (2.0B Active)
    – Two I2C Fast mode plus (1 Mbit/s) with 20 mA current sink, SMBus/PMBus, wakeup from STOP
    – Up to five USART/UARTs (ISO 7816 interface, LIN, IrDA, modem control)
    – Up to three SPIs, two with multiplexed half/full duplex I2S interface, 4 to 16 programmable bit frames
    – USB 2.0 full speed interface
    – Infrared transmitter
• Serial wire debug, Cortex®-M4 with FPU ETM, JTAG
• 96-bit unique ID
