OVERVIEW

MSquare's ONFI 5.1 PHY is a high-performance and low-power PHY IP, which supports all modes of the Open NAND Flash Interface (ONFI) 5.1 specification. ONFI is an interface connecting external flash particles (NAND Flash) and internal flash controller (NAND Controller), widely used in Solid State Drive (SSD) products. To simplify the implementation, MSquare ONFI 5.1 PHY supports expandable channels and customizable CE/RB pad numbers.
