AN218375 - Designing with Cypress Quad SPI (QSPI) F-RAM(TM)

AN218375 discusses Quad SPI (QSPI) and shows how to design with Cypress’ QSPI F-RAM. QSPI is an enhancement of the standard SPI protocol that provides four times the data throughput at higher frequencies while maintaining the compact form factor of the standard serial SPI. System designs using QSPI F-RAM devices occupy less board space with enhanced data throughput and features in a low-pin-count package, thus reduces overall system development and integration cost.
