1. Introduction
General description
i5062-ZD is a single-chip USB flash disk
controller which can handle up to four NAND-
type flash memory chips. It is compatible with
USB 1.1 and also compliant with USB 2.0. The
features of USB-boot-up and driver-less make
the flash disk very convenient for end-users.
i5062-ZD is designed with iCreate flash
interface technology to provide wear-leveling
and on-the-fly error-correction coding, which
enhance the life time of the disk. The flexibility
of the interface design also ensures supporting
to AND flash by firmware change and MLC
NAND flash in the protocol level.
For data security, i5062-ZD supports
multi-level protection mechanism. In the non-
protection level, data in the disk is fully
accessible. In low protection level, disk is read-
only to protect from virus and accidental file
removal. In high protection level, the disk data
cannot be accessed.
User-programmable device name based
on USB Mass Storage protocol (SCSI) is also
provided. The end-users can change the
device name that appears in Windows.
