A²SI-Lite 14 / A²SI-Lite 16 Low End Device AS-Interface IC Features 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. • • • • AS-i Complete Specification V2.11 compliant Integrated EEPROM Extended address mode operation as programmable option (up to 62 slaves) Dedicated IO-port structure: two data inputs, two data outputs, no parameter port pins Optional PWM outputs Integrated watchdog Temperature range -25°C to + 85°C The main advantage of AS-i solutions is that actuators and sensors are connected using a twowire 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.

A²SI-Lite 14 / A²SI-Lite 16 Low End Device AS-Interface IC Application The AS-interface integrated circuit A²SI-L is dedicated for pushbutton and pilot light applications. In contrast to the integrated circuit A²SI-L16 (16-pin SOP package) the A²SI-L14 does not provide diagnostic pins.
