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. Available packages range from 48 to 144 pins.
