Mobiveil’s Universal NOR Flash Controller (U-NFC) is a highly flexible and configurable design targeted for IOT, automotive, medical and consumer applications. The U-NFC primarily does memory-mapped access to external NOR Flash memories. The controller IP features very high read performances with High bandwidth NOR flash memories. The IP can function as simple ‘SPI Flash Controller’ or , ‘Quad-SPI Flash Controller’ or ‘Octa-SPI Flash Controller’ or ‘Dual QSPI Controller’. The controller architecture is SoC friendly and supports multiple chip-selects.
