Semiconductor intellectual property (IP) provider Cast has introduced a new version of the NAND Flash controller core that helps designers work with the latest advanced memory devices.

It does this by using faster error correction code, and by including better features for simplifying integration and improving performance in demanding system-on-chip (SoC) implementations.

The NAND Flash controller core is said to have configurable features that make it suitable for SSDs, consumer devices, and other specific, memory-intensive applications.

The controller core works with all memory devices that comply with the ONFI 2.2 standard, while also supporting the advanced performance features of some specific devices.

The core’s improved error correction code (ECC) ensures high-bandwidth transmission despite data errors by performing at-speed error detection and correction on up to 64 bits, using an improved Bose, Ray-Chaudhuri and Hocquenghem (BCH) implementation.

The controller now imposes less demand on a host system’s processor by handling complex functions in hardware, including: integrated AES-256 data encryption; multi-page transfer; and automatic remapping of corrupted memory blocks.

It also has a comprehensive command set for easy memory access.

Cast said the controller reduces SoC integration challenges through several new or improved features.

Interfaces to standard system buses now include AMBA AHB and AXI, Avalon, Coreconnect PLB, and OCP.

Flexible integrated direct memory access (DMA) options range from a simple slave DMA with programmable FIFO thresholds to an advanced scatter-gather master DMA.

A boot-from-flash feature loads firmware to on-chip memory automatically during system booting.

The core is delivered with a refined set of software drivers, and a soft-PHY that designers can use to target any implementation technology.

Sourced from Cast partner Evatronix, the controller is available in configurations to suit different applications.

These include a small version that only supports asynchronous mode, which is suitable for long-term or boot-code storage, and a full-featured, high-speed version that is capable of managing up to 200MT/s for applications needing the full bandwidth of the latest memory devices.
