General Description

SN11088 is a high-performance integrated circuit to access the NAND type Flash memory via the USB 1.1 bus. It provides a flexible and cost efficient single chip solution for external storage applications such as USB Disk (Flash Disk). With the capability to be pin-to-pin compatible to SN11085/86/87, the current user of SN11085/86/87 can easily upgrade to SN11088 with no engineering effort needed at all. With all the features inherited from SN11085/86/87 like the low 6MHz system clock to reduce the EMI, the embedded translation table to eliminate the cost of external memory, the Sonix proprietary randomization algorithm to extend the lifetime of flash memory and ensure the product robustness, and the real time ECC correction function, the SN 11088 adds several other unique features to reduce the cost of the end product and meet the customer’s requirements.
