AN96589 DESIGNING WITH Infineon 1-MB QUAD SPI nvSRAM (Chinese)

AN96589 discusses the Quad SPI (QSPI) and shows how to design with Infineon's 1-Mb QSPI nvSRAM. QSPI is an enhancement of the standard SPI protocol that provides four times the data throughput while maintaining the compact form factor of the standard serial SPI. System designs using QSPI devices occupy less board space and ultimately lower system costs.
