September 2021AN5050 Rev 71/741AN5050 Application noteOcto-SPI interface on STM32 microcontrollers IntroductionThe growing demand for richer graphics, wider range of multimedia and other data-intensive content, drives embedded designers to enable more sophisticated features in embedded applications. These sophisticated features require higher data throughputs and extra demands on the often limited MCU on-chip parallel memories have been widely used so far to provide higher data throughput and to extend the MCU on-chip memory, solving the memory size and the performance limitation. However, this action compromises the pin count and implies a need of more complex designs and higher meet these requirements, STMicroelectronics offers several MCU products in the market with the new integrated high-throughput Octo-SPI interface (see the table below).
