ONFI 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


ONFI Controller IP Core is the intermediate stage between NAND Flash memory and master controller. It is designed to have high speed solution to manage Raw NAND Flash application. It supports Open NAND Flash Interface Working Group (ONFI) 2.2 standard. Two advanced architectures - register based and descriptor based provides high speed performance, flexibility, data integrity and device compatibility. Descriptor based architecture reduces amount of CPU intervention.The ONFI 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 up to 4 NAND Flash device selection, Supports 4KB and 8KB page size
  • Supports command repeat and auto address increment functionality, Supports Multiplane (interleave) and Multi LUN operation
  • Supports 8 bit data bus, Supports 4, 8 and 12 bit Error Correction per 512 bytes
  • Buffer with configurable buffer depth for read and write operation, Supports interrupt driven functionality
  • Supports ONFI 2.3 standard command set, Supports integrated 32 bit DMA interface selection
