The STM32F411 is often used in applications requiring high processing power (like sensor fusion) combined with low power, bridging the gap between basic microcontrollers and more complex application processors.
The STM32F411 is a high-performance, low-power ARM Cortex-M4 microcontroller operating at up to 100 MHz with a FPU, up to 51 KB Flash, and 128 KB SRAM. It is known for its "Dynamic Efficiency" line, featuring Batch Acquisition Mode (BAM) for optimized power consumption during data processing, making it ideal for wearable and sensor application.
Performance: At 100 MHz, the STM32F411 delivers 125 DMIPS/339 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 when executing from Flash memory to be as low as 100 µA/MHz.
In Stop mode, the power consumption can be as low as 10 µA.
Integration: The STM32F411 devices carry 256 to 512 Kbytes of Flash and up to 128 Kbytes of SRAM.
The available packages range from 49 to 100 pins.
3x USARTs running at up to 12.5 Mbit/s,
5x SPI (muxed with I2S) running at up to 50 Mbit/s,
3x I²C up to 1Mbps
1x SDIO running at up to 48MHz and available on all packages,
1x USB 2.0 OTG full speed,
2x full duplex I²S up to 32-bit/192KHz,
3x simplex I²S up to 32-bit/192KHz,
12-bit ADC reaching 2.4 MSPS,
11 timers, 16- and 32-bit, running at up to 100 MHz
