PL-2518
Turbo Hi-Speed USB Flash Disk Controller
OVERVIEW
The PL-2518 Turbo Hi-Speed USB Flash Disk Controller is an integrated circuit that supports data transfer
between USB-equipped hosts (such as PC, PDA, MP3 Player) and NAND flash memory through the USB
port at Hi-Speed transfer rate of 480Mb/s. This single chip controller consists of a hub and two
mass-storage-class devices. It allows interface of up to 16 NAND flash memories to reach maximum 8GB
disk size capacity with enhanced R/W performances up to 20MBytes/sec and 15MBytes/sec respectively.
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 using the USB Flash Disk (UFD) utility program. To access the
secured mass storage device or disk, users must first enter a password using the UFD utility program. The
PL-2518 also allows a read-only function for the secured mass storage partition so users/vendors can
preload their software driver and application program, or any other software utilities into the partition to
save on extra disk cost and to enhance user-friendliness.
To take advantage of Plug and Play, the mass storage device is implemented according to the USB mass
storage device class. Since the default driver is included within most of the current OS, no extra driver is
needed for Linux, Mac OS, Windows ME/2000/XP and above. Prolific provides a separate Windows 98
driver and supports driver and utility customization.
The PL-2518 also provides options to customize this chip in showing the vendor identity. Users could
modify the Vendor ID, Product ID, Language ID, manufacturer string, and product string of the final
product.
