product brief

Overview
     JMF612 is a single chip, supports external SDRAM, SATA II to NAND flash interface. It is native design to provide higher bandwidth for flash memory access.
    JMF612 can support the maximum read and write speed to drive the limit of flash memory. JMF612 has the best supporting to the latest NAND flash memory, including Samsung, Toshiba, Hynix, Micron and IM Flash. It also provides the embedded hardware error correction code (ECC), wear leveling, and bad block management technology in this chip. In order to resolve compatibility issue, JMF612 provides the on line firmware upgrade ability.
    JMF612 provides embedded processor, internal masked ROM, data SRAM, SATA link/transport layer, SATA PHY. Data swap between different interfaces can be done very efficiency by DMA without CPU involvement. Based on the efficient architecture, the JMF612 can provide the best performance.
