Description：

STM32H753xI devices are based on the high-performance Arm® Cortex®-M7 32-bit RISCcore operating at up to 480 MHz. The Cortex® -M7 core features a floating point unit (FPU)which supports Arm® double-precision (IEEE 754 compliant) and single-precision dataprocessing instructions and data types. STM32H753xI devices support a full set of DSPinstructions and a memory protection unit (MPU) to enhance application security.STM32H753xI devices incorporate high-speed embedded memories with a dual-bank Flashmemory of 2 Mbytes, up to 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, up to864 Kbytes of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range ofenhanced I/Os and peripherals connected to APB buses, AHB buses, 2x32-bit multi-AHBbus matrix and a multi layer AXI interconnect supporting internal and external memoryaccess.All the devices offer three ADCs, two DACs, two ultra-low power comparators, a low-powerRTC, a high-resolution timer, 12 general-purpose 16-bit timers, two PWM timers for motorcontrol, five low-power timers, a true random number generator (RNG), and a cryptographicacceleration cell. The devices support four digital filters for external sigma-delta modulators(DFSDM). They also feature standard and advanced communication interfaces.
