A NAND Flash Controller IP implements the necessary logic required to interface user data with a NAND Flash memory device. The NAND Flash Controller IP Core performs operations such as Block erase, Page program, and read operations with other mandatory commands which enables access for the NAND device to the user.
iWave’s ONFI 2.0 compliant NAND Flash Controller IP Core is a fully featured, easy-to-use, synthesizable design that can be easily integrated into any SoC or non-SoC FPGA-based platform. Designed to support SLC flash memories, the NAND Flash Controller is flexible to use and implement. The NAND Flash IP Core also adds a faster, asynchronous, or synchronous I/O interface to meet today’s demanding high-performance needs.
The iWave NAND flash IP core allows a designer to quickly and efficiently integrate NAND flash memory functionality into their designs to make use of NAND flash memory capabilities to their design without having to develop the controller logic from scratch. By using an IP core, customers can reduce development time, cost, and risk, and focus on adding value to their end products.
The Key features supported by iWave’s NAND host controller IP are,
The NAND Flash Controller IP has been validated on multiple FPGA platforms including Xilinx, Intel, Lattice, and Microchip. Check out the resource utilization document for more information. iWave’s NAND host controller IP has been thoroughly validated with multiple FPGA device families and is well suited for various defense, space, and avionics applications.
NAND Flash Controller IP is available in three variants depending on the availability of the processor on the FPGA device selected by the user.
iWave offers a “Complete IP Solution” for its NAND Flash Controller IP core, which includes RTL source code, synthesis scripts, a test environment, and documentation, as well as world-class customer support.
With strong competence in FPGA, iWave Systems has demonstrated the seamless integration of iWave’s NAND Flash Controller IP functionality on the Zynq 7000 evaluation kit.
iWave NAND host controller IP Demonstration:
iWave NAND host controller functionalities such as device detection, NAND erase, program, and read operations are demonstrated by using the Zynq 7000 evaluation kit and NAND FMC daughter card. Furthermore, this demo also includes mounting, partitioning and erase, program, and read operations using JFFS2 file system and the UBI file system.
The NAND Linux driver, which is implemented in the Zynq 7000 SoC ARM core, communicates with the NAND host controller via the AXI4 lite interface for register access and the AXI4 memory-mapped interface for data transfer. The NAND host controller implemented in the FPGA communicates with the NAND device present in the FMC daughter card using the ONFI-defined NAND protocol. ARM core debug console is connected to teraterm where we run different commands to test the IP functionality.
