Overview
The STM32H757ZIY6TR is a high-performance microcontroller from STMicroelectronics, based on the Arm® Cortex®-M7 and Cortex®-M4 32-bit RISC cores. The Cortex®-M7 core operates at up to 480 MHz, while the Cortex®-M4 core operates at up to 240 MHz. Both cores feature floating point units (FPUs) supporting single- and double-precision operations, as well as a full set of DSP instructions and a memory protection unit (MPU) for enhanced application security.
This microcontroller incorporates 2 Mbytes of flash memory with read-while-write support, 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, 864 Kbytes of user SRAM, and 4 Kbytes of backup SRAM), and a wide range of enhanced I/Os and peripherals connected to APB, AHB, and AXI buses.
