Description
ASI-E is a monolithic CMOS integrated circuit
certified for AS-i (Actuator Sensor-interface)
networks. AS-i networks are intended for industrial
automation.
The main advantage of AS-i solutions is that
actuators and sensors are connected using a two-
wire unshielded cable that is easy to install. This
cable transports both power and information/data.
AS-i network communication is based on the
master-slave principle. The network can be
extended (to cable lengths greater than 100m) by
using the ASI-E in the repeater mode configuration.
Furthermore, the ASI-E is used as slave interface
to sensors / actuators and as master interface.
AS-i is a standard for the automation industry based
on IEC 62026-2 and EN 50295.
The device is available in a 28-pin SOP (300 mils)
package.

Application
The ASI-E is packaged in 28-pin SOP, which exhibits a lower thermal resistance than the 28-pin SSOP package
of ASI IC.
Besides applications that require higher operating ambient temperature than possible with ASI, ASI-E
accommodates applications which require a higher power dissipation of the integrated circuit. The thermal
resistance of the SOP package of the ASI-E integrated circuit is ideal for master and/or repeater applications.
