Overview
The SSC050 I2C Backplane Controller is a CMOS integrated circuit, which enables a system designer to reduce system cost by integrating all of the digital logic typically required in a storage enclosure. The SSC050 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 is easy through a convenient programming model, which reduces the overall duration of the design-in cycle. Data is read and written to the device over an addressable (3-bit) I2C serial interface, allowing multiple SSC050 devices on a single two-wire bus.
