The VSC055 Enhanced I2C Backplane
Controller is an integrated CMOS circuit
that significantly reduces system cost by
integrating all of the digital logic typically
required to monitor a storage enclosure.
The VSC055 may be used in any embedded control application
including parallel SCSI, Fibre Channel or any other application
where the monitoring and control of a large number of digital I/O
signals is required. Programming the VSC055 is easy through a
VSC055 APPLICA TION DIAGRAM:
convenient programming model, which reduces the overall
duration of the design-in cycle. Data is read from and written to
the device over an addressable I2C serial interface, allowing
multiple VSC055 devices on a single two-wire bus.
Furthermore, a key strength of the VSC055 is the ease in which it
interoperates with Vitesse Fibre Channel port bypass circuits
(PBC) and Enclosure Management Controllers, to provide a
complete storage control chipset.
