SAP5S / SAP51 Universal Actuator-Sensor Interface IC Datasheet Revision C Description Features SAP5 is a monolithic CMOS integrated circuit Universal application in AS-i Slave, Mas- certified for AS-i (Actuator Sensor Interface) ter, Repeater and Bus-Monitor compo- networks. AS-i networks are used for industrial nents automation. Support of AS-i Complete Specification AS-i is designed for easy and simple intercon- V3.0, including all optional features nection of binary sensors and actuators. It Synchronous Data I/O Mode - uses a two-wire unshielded cable to transport - 4 Input / 4 Output operation in power and information. Extended Address Mode Using the SAP5 safety-related AS-i slaves can - User write protection for be realized according to the AS-i Safety at Extended ID-Code 1 Work concept. Slaves complying with cate- - Multiplexed Parameter Port gory 4 of EN954-1 can be realized with a minimum of external circuitry. Full support of the AS-i Safety at Work concept The device is available in SOP20 and SOP16 package. On chip electronic inductor with current drive capability of 55mA LED outputs supporting all status indica- Application Support tion modes defined by AS-i Complete Configuration of the chip is handled through Specification V3.0 programming of the on-chip EPROM. ZMD Data preprocessing functions: input filter- provides special tools to ease product evalua- ing and input inverting tion and selection of different operation modes. Support of 5.33 / 16 MHz crystals by auto- matic frequency detection AS-Interface Programmer 2.0 USB Clock Watchdog for high System Security (Ordering Code: 3600100145) Communication Watchdog SAP5 Evaluation Board 2.0 (Ordering Code: 3600100144) Further application support is available through e-mail hotline under asi zmd.de P1 P2 SAP5 P0 P3 D1 D2 D1 D2 SAP5 D0 D3 D0 D3 DSTBn PSTBn DSTBn PSTBn LED1 LED2 LED1 LED2 OSC2 PFAULT OSC2 PFAULT OSC1 UOUT OSC1 UOUT U5R CDC U5R CDC LTGN LTGP LTGN LTGP Rev. 2.0 Copyright 2007, ZMD AG All rights reserved.
