Shenzhen Meiyuxin Technology Co., Ltd. [MCU agent] brand new original STM32H745BIT6 ARM® Cortex®-M4/M7 STM32H7 microcontroller IC 32-bit dual-core 240MHz, 480MHz 2MB (2M x 8) flash memory 208-LQFP (28x28)! !

Product Description:

STM32H745xI/G devices are based on the high-performance Arm® Cortex®-M7 and Cortex®-M4 32-bit RISC cores. The Cortex®-M7 core operates at up to 480 MHz and the Cortex®-M4 core at up to 240 MHz. Both cores feature a floating point unit (FPU) which supports Arm® single- and double-precision (Cortex®-M7 core) operations and conversions (IEEE 754 compliant), including a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.

STM32H745xI/G devices incorporate high-speed embedded memories with a dual-bank Flash memory of up to 2 Mbytes, up to 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, up to 864 Kbytes of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range of enhanced I/Os and peripherals connected to APB buses, AHB buses, 2x32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memory access.
