STM32F401 microcontrollers are part of the STM32 Dynamic Efficiency™ device
range. These devices offer the best balance of dynamic power consumption (in
run mode) and processing performance, while integrating a high number of
added-value features in packages as small as 3 x 3 mm.
MCUs deliver the performance of Cortex®-M4 core with floating point unit,
running at 84 MHz, while achieving outstandingly low power consumption values
in run and stop modes.
Performance: At 84 MHz, the STM32F401 delivers 105 DMIPS/285
CoreMark performance executing from Flash memory, with 0-wait states using
ST’s ART Accelerator. The DSP instructions and the floating point unit
enlarge the range of addressable applications.
Power efficiency: ST’s 90 nm process, ART Accelerator and the
dynamic power scaling enables the current consumption in run mode and
executing from Flash memory to be as low as 128 µA/MHz. In Stop mode, the
power consumption can be as low as 9 µA.
Integration: The STM32F401 portfolio provides from 128
to 512 Kbytes of Flash, 96 Kbytes of SRAM. The available packages range
from 49 to 100 pins..
3x USARTs running at up to
4x SPI running at up to 42
1x USB 2.0 OTG full speed,
2x full duplex I²S up
to up to 32-bit/192KHz,
12-bit ADC reaching 2.4 MSPS,
10 timers, 16- and 32-bit,
running at up to 84 MHz
