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 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.
