PL-2307
USB TO ATAPI-4 Bridge Controller
OVERVIEW
The PL-2307 integrated circuit provides a high-speed bridge between the Universal Serial Bus (USB) system
and ATAPI-4 compliant peripheral devices. It is designed to be a flexible, high performance, and low-cost
single-chip solution for USB-to-IDE cable as well as USB ready external "IDE Box" manufacturers.
PL-2307 supports most commands and features as defined by ATAPI-4 commands. The user will be able to
customize the chip and show their identity through the external serial EEPROM support. The user could also
modify the Vendor ID, Product ID, Language ID, manufacturer string, product string, and serial number
strings of the final product. Furthermore they could use this EEPROM to store authorization/security codes.
For large quantity orders, it is also possible to modify the Maskable ROM (Read Only Memory) of PL-2307 to
better represent the final product manufacturer and thus eliminate the need for external EEPROM.
