1.0 Overview
PL-2520 is an advanced Hi-Speed USB Flash Disk controller that allows fast data transfer between
USB-equipped hosts (such as PC, PDA, MP3 Player) and NAND Flash Memory through USB port
interface at transfer rate of 480Mbps. Advanced mode design allows for PL-2520 USB Flash devices
to reach enhanced Read/Write performances of 34MByte/sec and 24MByte/sec respectively. It also
allows interface of up to 8 NAND Flash Memory.
The available NAND flash memories on board can generally be used as a normal single disk or
partitioned into a standard/open mass storage device and a secured mass storage device. The sizes
of the partitions can be easily configured and adjusted by end-users using the USB Flash Disk (UFD)
utility program. To access the secured mass storage device or disk, users must first enter the correct
password using the UFD utility program.
Other features of PL-2520 are the Read-Only and Hidden Partition (Optional). The PL-2520 allows
vendors to create a read-only partition for preloading their software driver and application program to
save on driver CD cost and enhance user-friendliness. If a secured partition and password is set, this
Read-Only partition will toggle with the Secured partition disk after the password is confirmed. When
you plug-in the device, the Read-Only partition and the open partition will first appear and after the
end-user enters the password, the Read-Only partition will be removed and the Secured partition will
appear. The Hidden partition allows vendors to put their own private application programs and using a
special utility to access it. This Hidden partition is not accessible and cannot be seen by end-users.
Prolific provides a vendor manufacturing kit utility to customize and preset these special partitions.
To take advantage of Plug and Play, the mass storage device is implemented according to the USB
mass storage device class. Since the standard USB mass storage driver is included within the OS, no
extra driver is needed for Linux, Mac OS, Windows Vista, and Windows ME/2000/XP/2003 Server.
Prolific provides a separate Windows 98 driver and supports driver and utility customization. PL-2520
also supports Vista ReadyBoost requirements for both SLC and MLC NAND flash configurations.
PL-2520 also provides options to customize the chip in showing the vendor identity. Vendors could
modify the Vendor ID, Product ID, Language ID, manufacturer string, and product string of the final
product for their customization needs. Production configuration and test tool utilities are also provided
by Prolific. PL-2520 is the best solution for securer, low power, high performance and compatibility,
plug-and-play portable flash storage media.
