| www..com ASI-Lite 14 / ASI-Lite 16 Low End Device AS-Interface IC Features * * * * * * * 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 -25C to + 85C Description ASI-Lite (ASI-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 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 ASI or ASI-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.

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