Theory of Operation
2.3.1 Power Modes
•
Normal Power Mode (NPM) – The module is constantly powered on and polling for
cards. The module is never asleep in this mode. Use this mode with an external
power supply. The module is always ready to receive a command from the host.
•
Ultra Low Power Mode (ULPM) – This power mode was designed for fixed
location battery powered applications (for example, door or cabinet lock). The
module is constantly monitoring the antenna for an impedance shift to detect a card
presented to the antenna. Once detecting an impedance shift on the HF antenna,
the module wakes up and polls for cards in the field. If a card is detected in the RF
field, the module reads the card data, pulses the Card Present line, outputs the card
data, and goes back to sleep within a configured period of time to conserve power.
Note: If developing a handheld unit, operate the iCLASS SE Reader Module in Normal
Power Mode and disable the power when not in use.

2.3.2 Module – Transponder Interaction
•
Autonomous Mode – The iCLASS SE Reader Module is intended to automatically
access and report the secure payload or the serial number (UID/CSN) of a
transponder. Thereby it acts on its protocols and applications configuration to
automatically report the payload on its Wiegand, UART and/or SPI ports.
Advanced Protocol Interface Mode (API) – The host communicates with the
Advanced Protocol Interface Mode (API) – The host communicates with the
transponder in the field through the iCLASS SE Reader Module’s serial protocol.
(UART or SPI is required)
Note: API calls are available in ULPM after the module outputs its autonomous data
(configuration dependant).
