A²SI-Lite 14 / A²SI-Lite 16

Low End Device AS-Interface IC

Description

Features

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 two-

wire unshielded cable that is easy to install. This

cable transports both power and information/data.

•

AS-i Complete Specification V2.11 compliant

Integrated EEPROM

Extended address mode operation as

programmable option (up to 62 slaves)

•

Dedicated IO-port structure: two data inputs,

two data outputs, no parameter port pins

Optional PWM outputs

Integrated watchdog

Temperature range -25°C to + 85°C

•

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.

AS-i is a standard for the automation industry based

on IEC 62026-2 and EN 50295.

The device is available in a 14 and 16-pin SOP (150

mils) package.

A²SI-Lite 14 / A²SI-Lite 16

Low End Device AS-Interface IC

Application

The AS-interface integrated circuit A²SI-L is dedicated for pushbutton and pilot light applications. In contrast to

the integrated circuit A²SI-L16 (16-pin SOP package) the A²SI-L14 does not provide diagnostic pins.
