em | echo-V (EM4425)- NFC & High Frequency ICs, EPC and UHF ICs

RAINFC Authenticity Transponder IC

General Description

em|echo-V (also known by its order code EM4425) corresponds to the latest generation of EM Microelectronic RAINFC devices, bringing innovative features to the HF, NFC, and RAIN RFIDTM worlds. The chip combines all functionalities on a single die, with NFC for proximity range, HF for vicinity range, and RAIN technology used for long range application purposes. All protocols make use of a shared memory and a common IC serial number. Targeted applications and market segments include retail, product authentication, consumer engagement, industrial, automotive, and aerospace logistics. A tag or label based on the em|echo-V provides multiple benefits and usages via the RAIN communication interface like stock inventory, product returns, and data privacy. The same tag or label also enables new consumer services like product authentication, product information, or loyalty programs using an NFC enabled smartphone. The chip is a dual frequency device supporting ISO/IEC 15693, ISO/IEC 18000-3 Mode 1, NFC Forum Type 5 Tag, ISO/IEC18000-63, EPCTM Gen2v2, and ISO/IEC 29167-10.  The em|echo-V offers a user configurable non-volatile memory which is accessible by NFC, HF, and UHF air interfaces.
