The STM32F412 microcontrollers are the entry-level devices to the high-performance STM32F4 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 3.653 x 3.651 mm.
The STM32F412 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 STM32F412 takes Dynamic Efficiency to a new level. This BAM allows exchanging batches of data through communication peripherals while the rest of the device (including the CPU) remains in Power-saving mode.
- Performance: At 100 MHz, the STM32F412 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 dynamic power scaling enables the current consumption when executing from Flash memory to be as low as 112 µA/MHz. In Stop mode, the power consumption can be as low as 18 µA.
- Integration: The STM32F412 devices carry 512 to 1024 Kbytes of Flash memory and up to 256 Kbytes of SRAM.

As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
