The Initio INIC-1530 is a fourth generation UDMA 100 ATA-to-USB 2.0-1394a bridge
controller that provides a solution to connect ATAPI or ATA devices to USB 2.0 and
IEEE-1394a-2000 interfaces. It is designed to accelerate the time-to market for
1394a / USB 2.0 capable peripheral devices by integrating an already proven
1394a-2000 core with a USB 2.0 core and microprocessor with the necessary IDE
interface into a single ASIC. The SBP-2 (Serial Bus Protocol) compliant firmware is
stored in an external ROM (Flash). Supporting data transfers of up to 480Mbits/sec.,
the INIC-1530 IDE interface supports UltraDMA (100/66/33) modes making it feasible to
be used in many USB 2.0/1394 applications.

The1530 integrates a High Speed USB 2.0 core that will support both USB 1.1 as well as
USB 2.0 480Mbit connectivity. This coupled with the 1394a core provides a cost effective
high performance connectivity solution.

Device Support

INIC-1530 supports peak

data transfer rates of 480Mbits
per second in USB 2.0 mode
and 400Mbits in 1394a mode
which is sufficient for effective
integration of a number of
peripheral devices targeted for
use in a professional desktop
computing environment. The
current architecture satisfies
the bandwidth and Plug 'N'
Play requirements for seam-
less integration of devices
such as:

Hard Disk Drives

CD-RW/DVD Devices

Tape Drives

Removable Media
