The 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.
The 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 10.5 Mbit/s,
