STM32H743IIT6 LQFP-176 microcontroller ST original stock
Description
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.
All the devices offer three ADCs, two DACs, two ultra-low power comparators, a low-power
RTC, a high-resolution timer, 12 general-purpose 16-bit timers, two PWM timers for motor
control, five low-power timers and a true random number generator (RNG). The devices
support four digital filters for external sigma-delta modulators (DFSDM). They also feature
standard and advanced communication interfaces.

– One SPDIFRX interface
– One SWPMI (Single Wire Protocol Master Interface)
– Management Data Input/Output (MDIO) slaves
– Two SDMMC interfaces
– A USB OTG full-speed and a USB OTG high-speed interface with full-speed
capability (with the ULPI)
– One FDCAN plus one TT-CAN interface
– An Ethernet interface
– Chrom-ART Accelerator™
– HDMI-CEC
