Description

ASI4U and ASI4U-E are monolithic CMOS

integrated circuits certified for AS-i (Actuator

Sensor Interface) networks. AS-i networks are

used for industrial automation.

AS-i is designed for easy and simple intercon-

nection of

uses a two-wire unshielded cable to transport

power and information.

ASI4U and ASI4U-E are direct successor of

the A²SI IC and can replace the A²SI.

AS-i Safety applications can use the special

AS-i Safety Mode if fault reaction time is a

concern.

The device ASI4U is available in SSOP28

package. The device ASI4U-E in SOP28 pack-

age.

ASI4U-E has extented operation temperature

range from –25°C to +105°C.

Application Support

Configuration of the chip is handled through

programming of the on-chip E²PROM.

ZMD provides a special

to ease product evaluation and selection of

different operation modes.

Further application support is available through

the e-mail hotline
