STM32 Dynamic Efficiency MCU with BAM, High-performance and DSP with FPU, ARM Cortex-M4 MCU with 1 Mbyte Flash, 100 MHz CPU, Art Accelerator, DFSDM

STM32F412xE/G devices are based on the high-performance ARM® Cortex® -M4 32-bit RISC core operating at a frequency of up to 100 MHz. Their Cortex®-M4 core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.

STM32F412xE/G devices belong to the STM32 Dynamic Efficiency™ product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing even more power consumption saving during data batching.

STM32F412xE/G devices incorporate high-speed embedded memories (up to 1 Mbyte of Flash memory, 256 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

All devices offer one 12-bit ADC, a low-power RTC, twelve general-purpose 16-bit timers, two PWM timers for motor control and two general-purpose 32-bit timers.

They also feature standard and advanced communication interfaces.
