Enhanced ClearNAND Controller

Block Diagram

Solution Type: IP Core

End Market: Computer & Storage, Consumer

Evaluation Method: OpenCore Plus

Technology: Memory Interfaces and Controllers: Flash

Cyclone Series: Cyclone® IV, Cyclone® V


Enhanced ClearNAND Controller IP Core is the intermediate stage between NAND Flash memory and master controller. It is designed to have high speed solution to manage NAND Flash application. It supports Open NAND Flash Interface Working Group (ONFI) standard. Two advanced architectures - register based and descriptor based, provides high speed performance, software flexibility, data integrity and device compatibility. Descriptor based architecture reduces amount of CPU intervention.Enhanced ClearNAND Controller IP Core gives full support for Intel® FPGA's Platform Designer (formerly Qsys) based systems and provides communication between processor and NAND Flash device using Avalon interface.


  • Supports ONFI EZ NAND 2.3 plus enhanced command set
  • Supports integrated 32 bit DMA interface for data transfer, Supports interrupt driven functionality
  • Supports [0-5] asynchronous and [0-5] source synchronous modes of operation
  • Supports 8 bit data bus, Configurable buffer depth, Multi-Plane (interleave) operation support
  • Supports command repeat and auto address increment functionality
