AS-Interface Spec. V3.0

Compliant Universal AS-i IC

SAP51 / SAP5S

Datasheet

Brief Description

The SAP5S/SAP51 is a next-generation CMOS inte-

grated circuit for AS-Interface networks. This low-

level field bus AS-i (Actuator Sensor Interface) was

designed for easy, safe, and cost-effective inter-

connection of sensors, actuators, and switches. It

transports both power and data over the same two-

wire unshielded cable.

The SAP5S/SAP51 is used as part of a master or

slave node and functions as an interface to the

physical bus. It provides the power supply, physical

data transfer, and communication protocol handling.

The SAP5S/SAP51 is fully compliant with the

AS-Interface Complete Specification V3.0.

It is func-

tion and pin compatible with the SAP4.1 (AS2702).

The SAP5S/SAP51 can be programmed by the user

to operate in Standard Slave Mode, Safety Mode

(SAP5S only), or Master Mode. The special AS-i

Safety Mode (SAP5S only) assures short response

times regarding security-related events.

All configuration data are stored in an internal

EEPROM that can be easily programmed by a sta-

tionary or handheld programming device.

The SAP5S/SAP51 is optimized for harsh environ-

ments by its special burst protection circuitry and

excellent electromagnetic compatibility.
