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.
