AS-i networks are used for industrial automation. AS-i is designed for easy and simple interconnection of binary sensors and actuators. It uses a two-wire unshielded cable to transport power and information. ASI4U is a direct successor of the A²SI IC and can replace the A²SI in existing board layouts. AS-i Safety applications can use the special AS-i Safety Mode if fault reaction time is a concern. The device is available in SSOP28 package. - - - - - Application Support Configuration of the chip is handled through programming of the on-chip E²PROM. ZMD provides a special AS-Interface Programmer Tool (Ordering Code: ZMD ASI-Programmer ) to ease product evaluation and selection of different operation modes.
