Hyperstone F3 Block Diagram

The F3 CF/PATA NAND FLASH targets high-speed CF cards and PATA/IDE Solid State Disk Drives. This controller is derived from the Hyperstone E1 32-bit RISC/DSP processor. The F3 contains dual flash channels, each with its own DFA processor (Direct Flash Access-similar to DMA), and two sector buffers per channel. It supports all flash vendors and is optimized for 2-kbyte/page SLC flash. The F3 supports CFA4.0 and ATA6 specifications and is capable of sustained speeds of greater than 40MB/sec read and greater than 30 MB/sec write. Commercial and industrial temperature versions are available. Robust flash management and patented wear leveling are implemented in firmware stored in the flash. A complete set of software tools is provided for card initialization and preformatting.
