SAP51 / SAP5S AS-Interface Spec. V3.0 Compliant Universal AS-i IC Datasheet Brief Description Benefits The SAP5S/SAP51 is a next-generation CMOS inte- Cost savings due to integrated Safety Code grated circuit for AS-Interface networks. This low- Generator (SAP5S only) level field bus AS-i (Actuator Sensor Interface) was Special burst protection circuitry designed for easy, safe, and cost-effective inter- Excellent electromagnetic compatibility connection of sensors, actuators, and switches. It transports both power and data over the same two- Physical Characteristics wire unshielded cable. Operational temperature range: -25 to +85C The SAP5S/SAP51 is used as part of a master or slave node and functions as an interface to the SOP16 and SOP20 package physical bus. It provides the power supply, physical data transfer, and communication protocol handling. Available Support The SAP5S/SAP51 is fully compliant with the IDT AS-Interface Programmer Kit USB AS-Interface Complete Specification V3.0. It is func- IDT SAP5 Evaluation Board V2.0 tion and pin compatible with the SAP4.1 (AS2702). The SAP5S/SAP51 can be programmed by the user Related Products to operate in Standard Slave Mode, Safety Mode ASI4U Universal AS-Interface IC (SAP5S only), or Master Mode. The special AS-i Safety Mode (SAP5S only) assures short response times regarding security-related events.
