Advanced HyperRAM/PSRAM Usage on i.MX RT
■The i.MX RT series MCU is a crossover product from NXP. It includes a FlexSPI controller supporting HyperBus devices (HyperFlash/HyperRAM),Serial NOR Flash, or other device with similar SPI protocol as Serial NORFlash, and so on.
■How to Enable HyperRAM with i.MX RT (document AN12239) introduces the basic knowledge about how to enable HyperRAM with i.MX RT. This application note describes the advanced usage of HyperRAM/PSRAM when used with FlexSPI on i.MX RT MCU. The advantages include FlexSPI prefetch function, HyperRAM/PSRAM refresh interval, and HyperRAM devices supported for i.MX RT.
■This application note uses i.MX RT1050 and RT1170 as examples. HyperRAM devices from different vendors and PSRAM device from Apmemory are used for test.
