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. Its Cortex®-M4 core features a Floating point unit (FPU) single precision which supports all ARM singleprecisiondata-processing instructions and data types. It also implements a full set of DSPinstructions 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.
