6 STM32H7x7I-EVAL hardware layout and configuration
The STM32H7x7I-EVAL Evaluation boards are designed around the STM32H7x7XIH6U (240+25-pin TFBGA
package) microcontroller. Figure 2 shows the hardware block diagram for STM32H7x7XIH6U and illustrates the
connection between the microcontroller and the peripherals (SDRAM, SRAM, NOR Flash, Twin Quad-SPI Flash,
color LCD, USB OTG connectors, USART, Ethernet, Audio, FDCAN, microSD 3.0 card and embedded ST-LINK).
Figure 3. STM32H7x7I-EVAL Evaluation board (top side) helps users to locate these features on the Evaluation
board. The mechanical dimensions of the board are showed in Figure 4. STM32H7x7I-EVAL Evaluation board
mechanical drawing .
