I²C Backplane Controller

The SSC050-01 I²C backplane controller is an integrated CMOS circuit that significantly reduces system cost by integrating all the digital logic typically required to monitor a storage enclosure. The SSC050-01 can 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 I²C bus.

Furthermore, a key strength of the SSC050-01 is the ease in which it interoperates with Maxim's Fibre Channel port bypass circuits (PBCs) and enclosure management controllers to provide a complete storage-control chipset.
