ST公司的M32H743XIH6U和STM32H753xI是32位ARM MCU,工作频率400MHz,具有856 DMIPS/ 2.14 DMIPS/MHz (Dhrystone 2.1)以及DSP指令,集成了多达2MB闪存,1MB RAM以及通信和模拟接口,主要用在马达驱动和应用控制,医疗设备,工业应用包括PLC,逆变器和断路器,打印机和扫描仪,告警系统,视频互连和HVAC,家庭音频设备,移动应用和物联网(IoT)以及可穿戴设备如智能手表.本文介绍了STM32H743xI和STM32H753xI主要特性,框图,以及评估板STM32H7x3I-EVAL主要特性,框图和电路图.
STM32H743xI devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 400 MHz. The Cortex® -M7 core features a floating point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H743xI devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.
STM32H743xI devices incorporate high-speed embedded memories with a dual-bank Flash memory up to 2 Mbytes, 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, 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.
