Quad-SPI interface on STM32 microcontrollers and ...
IntroductionIn order to manage a wide range of multimedia, richer graphics and other data-intensive content, embedded applications evolveto offer more sophisticated features. These sophisticated features place extra demands on the often limited micocontroller(MCU) and microprocessor (MPU) on-chip MCUs and MPUs are referred to as " STM32 devices" in this document. The devices that are concerned are listed in thetable 1.

Apr 28, 2020 · External parallel memories are used to extend the STM32 devices on-chip memory and solve the memory size limitation. Usually this action represents an increase in the pin count and implies a more complex design. To face these requirements, STM32 devices embed an external memory interface named Quad-SPI (see more details on Table 2).
