AS-I controller IC

27 June 2012 Analogue, Mixed Signal, LSI

ZMDI announced an additional member of its AS-Interface IC family, the ASI4U-F, designed for cold and harsh environments in process and factory automation applications.

It can be used at ambient temperatures ranging from


-40°C to +85°C, which minimises extensive and costly module tests.

The low-level fieldbus AS-I (actuator sensor interface) is designed for easy, safe and cost-effective interconnection of sensors, actuators and switches. It transports both power and data over the same two-wire unshielded cable, which is typically yellow. Bidirectional data exchange between one master and up to 62 slaves is possible.

The ‘F’ version of the ASI4U is functionally and pin-compatible with ZMDI’s ASI4U family in SSOP28 package and it conforms to the AS-Interface specification v3.0. It is also supported by the ZMDI AS-Interface development tools.
