Introduction
The EZ-USB AT2LP™ (CY7C68300C/CY7C68301C and
CY7C68320C/CY7C68321C) implements a fixed-function
bridge between one USB port and one or two ATA- or
ATAPI-based mass storage device ports. This bridge adheres
to the Mass Storage Class Bulk-Only Transport Specification
(BOT) and is intended for bus and self powered devices.
The AT2LP is the latest addition to the Cypress USB mass
storage portfolio, and is an ideal cost- and power-reduction
path for designs that previously used Cypress’s ISD-300A1,
ISD-300LP, or EZ-USB AT2.
Specifically, the CY7C68300C/CY7C68301C includes a mode
that makes it pin-for-pin compatible with the EZ-USB AT2
(CY7C68300A).
The
CY7C68320C/321A (AT2LP) are connected to a host
computer directly or with the downstream port of a USB hub.
Software on the USB host system issues commands and
sends data to the AT2LP and receives status and data from
the AT2LP using standard USB protocol.
