Description

The ASI4U-V5 ASSP is a silicon solution that implements an Actuator-Sensor-Interface version 5 (ASi-5)

fieldbus transceiver. It reduces the integration effort of an ASi-5 interface to a minimum. The implementation

of the complex transmission process is optimally distributed between hardware and firmware components.

Both slave options outlined in the ASi-5 specification are easily implemented. In simple slave mode, the chip

is only supplied with process data via digital I/O pins. For complex slave implementations, process data and

acyclic communication are handled via a serial interface. The compact, power-saving design enables the

development into small form factors.
