Features & Applications

The CY4615B AT2LP is a tool to demonstrate the features of the AT2LP (CY7C68300C and CY7C68320C) mass storage bridge chips.

This reference design supports the EZ-USB AT2LP (CY7C68320/CY7C68300B) products from Cypress. The EZ-USB AT2LP adds large capacity drive support and ATA interrupt request (IRQ) support, all in an easy-to-use, low-cost configurable device. By default, the AT2LP DDK board will be configured as a bridge to one or two ATA devices in a self-powered configuration. If you would like to use this board as a bus-powered device or if you would like to use the CompactFlash socket, you will need to change the board configuration using the jumpers on the DDK board and the PC-based programming utility.


  • Single-chip interface to any ATA/ATAPI or CompactFlash (Microdrives & CF) device
  • Support for ATA-6 specification for large capacity drives.
  • Support for up to UDMA mode 4.
  • Completely reconfigurable board to support self-powered or bus-powered applications.
  • ompatibility with Windows and Mac OS class drivers, Cypress drivers available.
  • Tri-state-able output lines.
  • Configurable EEPROM.
