2 Description
The STM32F401XD/XE 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 STM32F401xD/xE incorporate high-speed embedded memories (512 Kbytes of Flash
memory, 96 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 I
2
Cs
• Up to four SPIs
• Two full duplex I
2
Ss. To achieve audio class accuracy, the I
2
S 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 for the peripherals available for each part number.
The STM32F401xD/xE 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 STM32F401xD/xE 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
