The Lattice Octal SPI Controller IP is an SPI interface that supports different types of SPI protocols: standard, dual, quad, and xSPI. Standard SPI is the legacy four-wire interface with separate data lines for input and output. Dual SPI (DSPI) is an extension of standard SPI using two data lines. Quad SPI (QSPI) is another extension of standard SPI designed to provide a higher data transfer rate using four data lines. Expanded SPI (xSPI) is an advanced extension of standard SPI designed to provide higher data throughput and improved performance while maintaining backward compatibility with standard SPI devices. xSPI uses eight data lines and is capable of double data rate transfer.
Resource Utilization details are available in the IP Core User Guide.
