SSC050-01
I2C Backplane Controller
GENERAL DESCRIPTION:
The SSC050-01 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 SSC050-01 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
SSC050-01 is easy through a 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 SSC050-01 devices on a single two-wire bus.
Furthermore, a key strength of the SSC050-01 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.
