Description

A²SI-Lite (A²SI-L) is a monolithic CMOS integrated circuit certified for AS-i (Actuator Sensor-interface) networks. AS-i networks are intended for industrial automation. This integrated circuit is dedicated to be used as simplified interface IC for key control panels, simple sensors and small actuators.

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 A²SI or A²SI-E in the repeater mode configuration.

AS-i is a standard for the automation industry based on IEC 62026-2 and EN 50295.

The device is available in a 14 and 16-pin SOP (150 mils) package.
