Overview

NAND Flash is a non-volatile, high-density memory typically used for secondary storage or long term storage. NAND Controller provides an easy interface to access NAND Flash Memory devices. Mistral’s ONFI 3.0 NAND Controller IP core is available for Xilinx and Altera FPGAs and supports both Synchronous and Asynchronous modes of operation. The NAND Flash Controller can handle all the commands, address, data sequences, and hardware protocols.

NAND Controller devices usually have a complex and multiplexed device architecture which only support page Write/Read and Block Erase operations. The ONFI 3.0 NAND Flash Controller IP Core from Mistral provides an easy access to NAND Flash Controller devices over an 8-bit wide interface to handle multiplexed command, address and Write/Read data sequences.

Supporting ONFI 3.0 NAND controller standards, the NAND Flash Controller IP Core from Mistral  has several configurable features and parameters to customize the controller for the specific needs of diverse applications.

Mistral’s NAND Flash Controller IP Core is designed for Maximum Data Transfer Rate and Optimal Resource Utilization.
