Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd supplies and recycles [ST distributors] STM32H753IIK6 and STM32H753IIT6 STM32H7 high performance MCUs based on the high performance Arm® Cortex®-M7 32-bit RISC core.

Description:

The STM32H753IIK6 and STM32H753IIT6 STM32H7 MCUs support a full set of DSP instructions and a memory protection unit (MPU) for enhanced application security.

The MCUs feature high-speed embedded memory with up to 2MB of dual-zone Flash, 1 MB of RAM (including 192 KB of TCM RAM, 864 KB of user SRAM and 4 KB of backup SRAM). In addition, the device features a variety of enhanced I/O and peripherals connected to the APB bus, AHB bus, 2x32-bit multi-AHB bus matrix, and a multi-layer AXI interconnect supporting internal and external memory access.
