1. Introduction
i5127-L
General description
Features
i5127-L is a single-chip High-Speed USB
flash disk controller which can handle up to
two NAND-like flash memory chips. It is
compliant with USB 2.0 and also compatible
with USB 1.X. The features of USB-boot-up
and driver-less make the flash disk very
convenient for end-users.
i5127-L 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
both SLC NAND and MLC NAND flash. i5127-
L can also support flash with either 16-bit or 8-
bit data bus.
For data security, i5127-L supports
multiple protection level. 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.
