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.
