Brief Description
ASI4U is a new generation CMOS integrated circuit
for AS-I networks.
The low-level field bus AS-I (Actuator Sensor
Interface) was 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.
ASI4U is used as a part of a master or slave node
and works as an interface to the physical bus. The
device realizes power supply, physical data transfer
and communication protocol handling. ASI4U is fully
compliant with AS-I Complete Specification 3.0 and
functioning and PIN compatible with the A²SI IC.
All configuration data are stored in an internal
EEPROM that can be easily programmed by a
stationary or handheld programming device. The
special AS-I safety option assures short response
times regarding security related events.
Features
 Compliant with AS-I Complete Specification V3.0

 On-chip electronic inductor with current drive
 Two configurable LED outputs to support all Spec.
 Several data pre-processing functions, including
 Additional addressing channel for easy wireless
 Support of 8 / 16 MHz crystals by automatic
 Special AS-I safety option
 Clock watchdog for high system security
