Description:

The STM32F401XB/STM32F401XC devices are based on the high-performanceArm® Cortex® -M4 32-bit RISC core operating at a frequency of up to 84 MHz.The Cortex®-M4 core features a Floating point unit (FPU) single precision which supports allArm single-precision data-processing instructions and data types. It also implements a fullset of DSP instructions and a memory protection unit (MPU) which enhances applicationsecurity.The STM32F401xB/STM32F401xC incorporate high-speed embedded memories (up to256 Kbytes of Flash memory, up to 64 Kbytes of SRAM), and an extensive range ofenhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bitmulti-AHB bus matrix.

All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timersincluding one PWM timer for motor control, two general-purpose 32-bit timers. They alsofeature standard and advanced communication interfaces. 

• Up to three I²Cs

• Up to four SPIs

• Two full duplex I2Ss. To achieve audio class accuracy, the I2S peripherals can beclocked via a dedicated internal audio PLL or via an external clock to allowsynchronization.

• Three USARTs

• SDIO interface

• USB 2.0 OTG full speed interfaceThe STM32F401xB/STM32F401xC operate in the - 40 to + 125 °C temperature range froma 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving mode allowsthe design of low-power applications.These features make the STM32F401xB/STM32F401xC microcontrollers suitable for awide range of applications:

• Motor drive and application control

• Medical equipment

• Industrial applications: PLC, inverters, circuit breakers

• Printers, and scanners

• Alarm systems, video intercom, and HVAC

• Home audio appliances

• Mobile phone sensor hub
