Description

The QSPI interface on the Sitara AM437x processors enables system designers to connect a NOR flash. The interface is fast enough to support execute-In-Place (XIP). Such design  offers flexibility for code partitioning and system cost savings by enabling the use of lower cost NOR flash or less DDR memory.

Features
  • 512 Mega-bit NOR Flash connected over Quad-SPI interface to the Sitara AM437x processor
  • 4-pin SPI interface with external chip select signal
  • SPI MODE 3
  • Complete sub-system reference with schematics, BOM, design files, and HW User's Guide implemented on a fully assembled board developed for testing and validation.
