em | aura-air (EM4018)- EPC and UHF ICs

Fully integrated rain RFID transponder

General Description

em|aura-air corresponds to the latest generation of EM Microelectronic RAIN RFID devices, providing state-of-theart EPCTM Gen2v2 capabilities with integrated on-chip antenna.

Targeted applications and market segments include industrial, automotive, and aerospace track & trace applications as well as asset management. A tag or label based on the em|aura-air provides multiple benefits and usages via the RAIN communication interface like stock inventory, product returns, and data privacy.

Leveraging its integrated coil antenna, em|aura-air can be either used in short-range applications or provide long read range through a magnetically coupled external secondary booster antenna.

The chip supports ISO/IEC18000-63 and EPCTM Gen2v2 protocols and offers a user configurable non-volatile memory.
