| A2SI-E Advanced AS-Interface IC Features * * * * * * * * * * AS-i Complete Specification V2.11 compliant Integrated EEPROM Additional addressing channel using an optoelectronic interface Extended address mode operation as programmable option (up to 62 slaves) High impedance AS-i line input, additional pins for further impedance optimizations DC voltage output, approximately 24 volts, not stabilized 5 volt DC voltage output, stabilized, CMOS logic can be supplied directly (e.g. C) LED status indicator output (compliant with the standard indication recommendation) Integrated watchdog Temperature range -25C to + 105C 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 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-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.

A2SI-E Advanced AS-Interface IC 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.
