Overview¶

https://www.st.com/en/evaluation-tools/stm32h747i-disco.html

STM32H747I-DISC1 is the subset of STM32H747I-DISCO without the LCD display module.

The full range of hardware features available on the boards helps users improve application development by an evaluation of all the peripherals (USB OTG HS, Ethernet, microSD™ card, SAI Audio DAC stereo with audio jack input and output, MEMS digital microphone, SDRAM, Quad-SPI Flash, DCMI connector, MIPI® DSI interface, and others). Arduino™ Uno V3 and Pmod™/STMod+ connectors provide easy connection to extension shields or daughterboards for specific applications.

STLINK-V3E is integrated into the board, as the embedded in-circuit debugger and programmer for the STM32 MCU and USB Virtual COM port bridge.

Microcontroller main features¶

https://www.st.com/en/microcontrollers-microprocessors/stm32h747xi.html

STM32H747xI/G devices are based on the high-performance Arm® Cortex-M7 and Cortex-M4 32-bit RISC cores. The Cortex-M7 core operates at up to 480 MHz and the Cortex-M4 core at up to 240 MHz. Both cores feature a floating point unit (FPU) which supports Arm single- and double-precision (Cortex-M7 core) operations and conversions (IEEE 754 compliant), including a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.

STM32H747xI/G devices incorporate high-speed embedded memories with a dual-bank Flash memory of up to 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), 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, 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.
