62 / 91 page  LTDC application examples AN4861 62/91 DocID029237 Rev 2 Figure 31. Low-end graphic implementation example 6.1.2 MCU with external memory In order to interface with higher resolution displays, an external memory connected to the FMC is needed for framebuffer. An external QSPI Flash memory can be used to store graphic primitives. For mid-end or high-end graphical applications, the user can use the following hardware configuration example: • External QSPI Flash memory with up to 256 MByte addressable memory-mapped is used for storing graphic primitives. • External SDRAM 32-bit memory used for framebuffer. • STM32 MCU packages: UFBGA169, UFBGA176, LQFP176, LQFP208, TFBGA216, WLCSP168 and WLCSP180. Figure 32 illustrates a graphic implementation example where two external memories are connected to a STM32 MCU, one for the framebuffer and the other for graphic primitives. |
