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.
