Description
The high-performance Arm? Cortex?-M7 32-bit RISC CPU used in the STM32H753IIT6 chip operates at up to 480 MHz. The Cortex?-M7 core includes a floating point unit (FPU) that supports Arm? single-precision and double-precision (IEEE 754 compliant) data processing instructions. The memory protection unit (MPU) and the entire range of DSP instructions are supported by the STM32H753IIT6 device to increase application security.
The STM32H753IIT6 device includes high-speed embedded memories with a dual-bank Flash memory of 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), a wide variety of upgraded I/Os, and peripherals connected to APB and AHB buses, a 2x32-bit multi-AHB bus matrix, and a multi-layer AXI interface supporting internal and external memory access are all included.
A genuine random number generator (RNG), two PWM timers for motor control, five low-power timers, a high-resolution timer, three ADCs, two DACs, two ultra-low-power comparators, a low-power RTC, and a cryptographic acceleration cell are all provided by the devices. Four digital filters for external sigma-delta modulators are supported by the devices (DFSDM). They also have both conventional and cutting-edge communication interfaces.
