SMIF Diagram



The SMIF_PDL Component is a multifunction hardware block that implements the SPI communication to external serial memory devices, including the NOR Flash, SRAM, and non-volatile SRAM.

The SMIF_PDL Component is a hybrid graphical configuration entity with a set of Component-specific API built on top of the cy_smif driver available in the PDL. It allows schematic-based connections and hardware configuration as defined by the Component Configure dialog.
