Release Notes IC Revision C of modification The telegram reception under worst case capacitive and worst case inductive network conditions was improved in response to suggestions of the technical committee of the AS-International Association. The digital MAN-code communication channel does now support a more cost effective two-wire data transfer between the A²SI and the master control logic. It is not necessary to rely on the additional ‘Receive_Strobe’ signal, which is supplied at the parameter port P2 in Master Mode to verify the correctness of the MAN output signal at the LED port. The MAN signal is now distinctively disturbed if an erroneous telegram was detected at the AS-i input. This allows to spare at least one... |

Low End Device AS-Interface IC 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 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.
