LED Flash Rate Control
The built-in flexibility of the SSC050 allows all forty
of the I/O pins to drive LEDs through a pull-up
resistor. Each pin is independently programmed to
flash an LED at one of seven predefined flash rates.

Fan Speed Sensors
The SSC050 includes four pins (P2.4 to P2.7),
which may be configured as fan speed sensors.
This feature enables the designer to provide high
value monitoring features at significantly reduced
costs. Embedded controllers may access the
SSC050 to determine the rotational speed (RPM) of
fans attached to each of the four inputs. The
SSC050 may also be programmed to signal an
interrupt if any one of the speed sensors fall below
the designer’s predefined level.
FC-AL Port Bypass Control
Up to sixteen of the forty I/Os may be configured to
monitor and manage FC-AL port bypass control
devices. Eight pairs of I/Os include special logic to
monitor Enable Bypass signals, which may be
generated by FC-AL disk drives, and control Port
Bypass Control Enable (PBC_Enx) signals on port
bypass devices such as Vitesse’s VSC7122.
The unique functionality of the SSC050 provides
the system designer with additional flexibility and
control over the port bypass function in a FC-AL
enclosure. This allows system designers to
differentiate and add value by controlling when and
how a drive is removed or inserted into a FC-AL
enclosure.
This feature may also be used for non-FC-AL
applications. It is useful wherever system
designers require flexible monitoring and control of
backplane signals.
Interrupt Support
There are up to forty interrupt sources within the
SSC050. I/O pin signal transitions, fan speed
sensor threshold levels and transitions on port
bypass inputs may be configured to generate
interrupts. Advanced interrupt priority and
management logic provides the system designer
with maximum flexibility and a simple and
convenient programming method for handling
interrupts.
