Electrical Specifications
5.1
Maximum Ratings
Stresses beyond those listed may cause permanent damage to the device. This is a stress
rating and functional operation of the device at these or other conditions (beyond those
indicated in the operational sections) is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Current Draw
The following measurements were performed with a 50 Ohm load connected to the HF
interface. In the case a real antenna is connected to the iCLASS SE Reader Module’s power,
consumption changes depending on the presence of a transponder and its relative position to
the antenna. For that reason, find guidance for changing power consumption for particular
antennas in section 6 RF Interfaces.
The power consumption is independent of the supply voltage, as the iCLASS SE Reader
The power consumption is independent of the supply voltage, as the iCLASS SE Reader
Module uses a linear regulation system.

Polling cycle includes ISO/IEC14443 Type A and Pico15693. Adding additional protocols to the polling cycle may
vary the power consumption.

When the carrier is turned on, the current consumption of the module may build to create the required magnetic
field. The peak currents are also considered in the average current measurement.
