STM32F412VET3                 Description

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 dataprocessing 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.
