C Backplane Controller
Product Brief
Overview
The SSC050 I C 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) I
2
C serial interface, allowing
multiple SSC050 devices on a single two-wire bus.

C Serial Interface
The SSC050 uses an I
2
C serial interface to
communicate with embedded controllers such as
Vitesse鈥?SSC100/200 and VSC205/210. The slave
s
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 I
2
C 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
eight pins. Certain groups of pins have additional
functionality beyond simple input or output to
support the integrated fan speed sensors and
FC-AL port bypass control.
