System architecture on STM32F7x6, STM32F7x7, STM32F7x8 and STM32F7x9

The system architecture of the STM32F7x6, STM32F7x7, STM32F7x8 and STM32F7x9

lines consists mainly of 32-bit multilayer AHB bus matrix that interconnects twelve masters

and eight slaves. The LTDC is one of the twelve AHB masters on the AHB busmatrix.

The LTDC can autonomously access all the memory slaves on the AHB bus matrix, such as

FLASH, SRAM1, SRAM2, FMC or Quad-SPI enabling an efficient data transfer which is

ideal for graphical applications. Figure 10 shows the LTDC interconnection in the

STM32F7x6, STM32F7x7, STM32F7x8 and STM32F7x9 systems.
