PL-2315
USB Portable Flash Disk Controller
OVERVIEW
PL-2315 integrated circuit is a full-speed Portable USB Flash Disk Controller. There are a hub, two
mass-storage-class devices, and a “security device” integrated into this single chip. Up to four
state-of-the-art NAND flash memories can be interfaced as its storage media. The required USB hub
function is embedded to achieve the most cost-effective goal for multi-device solution.
The available NAND flash memories on board can be generally used as a normal single disk, or can be
partitioned into a 1M-byte accessory disk (auxiliary mass storage device), and a main disk (primary mass
storage device). To secure the privacy of the data, users have to pass the security check to get access to
the main disk. Customers can pre-load the driver and the application program of the “security device” into
the accessory disk to save an extra CD-ROM or floppy so to save the cost and to provide users more
convenience.
To take advantage of Plug and Play, the mass storage device is implemented according to the USB mass
storage class. Therefore, no extra driver is needed since the default driver is embedded within most of the
current OS.
