The Lattice xSPI Target IP is a flexible Serial Peripheral Interface (SPI) solution that supports both standard and quad SPI (QSPI) protocols. Designed for seamless integration in embedded systems, it enables reliable data transfer between microcontrollers and peripheral devices such as sensors, memory, and display controllers.
Standard SPI provides a legacy four-wire interface with dedicated input and output data lines, while QSPI extends this capability with four data lines for significantly higher data throughput. The xSPI Target IP accommodates both modes, giving designers the flexibility to optimize for compatibility or performance depending on their application requirements.
