NAND Flash Controller IP
The Posedge NAND Flash Controller IP is a flexible high performance Soft IP core capable of interfacing with NAND Flash devices fully conforming to standards such as the latest Open NAND Flash Interface Working Group (ONFI) 2.2 specification. ONFI 2.2 presents a clear evolutionary path to the NAND Flash storage by providing synchronous modes to achieve higher throughputs and to support higher density memories.
The Controller architecture is very generic and highly modular to address customer specific requirements with generic AXI/AHB/APB/FIFO Interfaces. The IP supports NAND flash accesses up to 200 MTps (Mega Transfers per second) with transfer size of 8bits or 16 bits depending on the mode of operation. To avoid data throttling on the Host processor side the IP core has an internal 16 deep Data Buffer which can queue up to 16 commands.
