ASI4U EVALUATION BOARD V2.0

The ASI4U EVALUATION BOARD V2.0 is an evaluation board which demonstrates the integration of the ASI4U IC in an application specific design case. The ASI4U is a new generation CMOS integrated circuit for AS-I networks. Actuator sensor Interface (AS-i) is the simplest automation networking solution and it is the ideal choice for networking sensors and actuators in factory automation and process control environments. The device realizes power supply, physical data transfer and communication protocol handling. This evaluation board helps to reduce development effort and development time for ASI4U application projects. It demonstrates an IC reference design, illustrates simple application circuits and deals with recommendations concerning necessary external components and PCB design issues.
