SSC050

SSC050 I2C Backplane Controller Product Brief 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. www.DataSheet4U.com Overview I2C Serial Interface The SSC050 uses an I2C serial interface to communicate with embedded controllers such as Vitesse’ s SSC100/200 and VSC205/210. The slave interface on the SSC050 uses a three-bit (A2:0) addressing scheme for identification on the serial interface. The ASEL pin determines the four-bit device type identifier. Up to sixteen, SSC050 or VCS055 devices may reside on a single I2C serial interface. I/O Pins The SSC050 has forty bi-directional I/O pins. The functionality of these pins is configurable via programming of the SSC050. All I/O pins have a 12mA drive strength and support 3.3V TTL. To enable the designer to configure and program the SSC050, the forty I/Os are arranged in registers of ei...
