10 / 134 page DocID024738 Rev 5 10/134 STM32F401xB STM32F401xC Description 53 2 Description The STM32F401XB/STM32F401XC devices are based on the high-performance ARM® Cortex® -M4 32-bit RISC core operating at a frequency of up to 84 MHz. Its Cortex®- M4 core features a Floating point unit (FPU) single precision which supports all ARM single- precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32F401xB/STM32F401xC incorporate high-speed embedded memories (up to 256 Kbytes of Flash memory, up to 64 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature 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 be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization. • Three USARTs • SDIO interface • USB 2.0 OTG full speed interface Refer to Table 2: STM32F401xB/C features and peripheral counts for the peripherals available for each part number. The STM32F401xB/STM32F401xC operate in the –40 to +105 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications. These features make the STM32F401xB/STM32F401xC microcontrollers suitable for a wide 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 Figure 3 shows the general block diagram of the devices. |
