Stm32f303cbt6 LQFP-48 ARM microcontroller - MCU STM advantage
Stm32f303xb / stm32f303xc series are based on * * arm ® Cortex ®- M432-bit RISC * *, FPU operating frequency up to 72mhz, and embedded floating point unit (FPU), memory protection unit (MPU) and embedded tracking macro unit (ETM). The series integrates high-speed embedded memory (more 256kby flash memory and more 40kby SRAM) and a wide range of enhanced I / OS and peripherals connected to two APB buses.
The equipment provides more 4 * * 12 bit ADCs (5msps), 7 comparators, 4 operational amplifiers, more two DAC channels, one low-power RTC, more five general-purpose 16 bit timers, one general-purpose 32-bit timer and two timers specially used for motor control. They also have standard and * * communication interfaces: more two i2cs, more three SPIs (two SPIs have multi-channel full duplex i2ss), three USARTs, more two UARTS, can and USB. In order to realize the accuracy of audio class, I2S peripherals can clock through external PLL.
The stm32f303xb / stm32f303xc series operate at - 40 to + 85 ° C and - 40 to + 105 ° C with a temperature range of 2.0 to 3.6V power supply. A comprehensive set of energy-saving models allows the design of low-power applications.
Stm32f303xb / stm32f303xc series provide four package devices, ranging from 48 pins to 100 pins. The set of peripherals included varies with the selected device.
