The STM32F411 microcontrollers are part of the STM32 Dynamic Efficiency? lines. These devices are the entry level to the High Performance F4 Series and 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 STM32F411 MCUs deliver the performance of Cortex?-M4 core with floating point unit, running at 100 MHz, while achieving outstandingly low power consumption values in run and stop modes.

With a new, Batch Acquisition Mode (BAM), optimizing power consumption for data batching, the STM32F411 takes the Dynamic Efficiency to a new level. This BAM allows exchanging batches of data through communication peripherals with the rest of the device (including the CPU) being in power saving mode.

  • 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
