SSC050

I

2C Backplane Controller

Product Brief

Overview

The SSC050 I

2C 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

2C serial interface, allowing

multiple SSC050 devices on a single two-wire bus.

Device Features

• I2C Serial Interface (DC to 400Khz)

• 4 Fan Speed Monitor Inputs

• 40 Programmable, Bi-directional I/O Pins

• Flexible FC-AL Port Bypass Control Logic

• Bit Programmable Interrupt Control

• Seven LED Flash Rates

• 64 PQFP Package

I

2C Serial Interface

The SSC050 uses an I

2C 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 I

2C 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.
