FACT SHEET | EM4423 Subject to change without notice Version 2.0, 14-Dec-15 Copyright © 2015, EM Microelectronic-Marin SA www.emmicroelectronic.com DUAL Frequency NFC Type 2 & EPC GEN2V2 Transponder IC General Description Features EM4423 corresponds to the latest generation of EM Microelectronic contactless devices, bringing innovative features to the NFC and EPCTM worlds. The chip combines two functionalities on one single die, the EPC technology used for long range application purposes and the NFC used to exchange data in a proximity range. Both protocols may share a common unique ID. I Dual Frequency 1-step inlay manufacturing Targeted applications and market segments include retail, product authentication or smart NFC posters. A tag or label based on the EM4423 provides multiple benefits and usages via the EPC communication interface like stock inventory, product returns, and data privacy. The same tag or label also enables new marketing services like product information or loyalty programs using an NFC enabled smartphone. The chip is a dual frequency device supporting ISO/IEC14443 Type A, NFC ForumTM Type 2 specifications, ISO/IEC18000-63 and EPC Gen2 V2. Additional features have been added to provide chip privacy. For the NFC interface, the smart counter increments its value each time the NFC message has been read by the end-user. Each chip is manufactured with a 96-bit unalterable unique identifier (UID) to ensure full traceability. The same UID number is used by both RF protocols. During an ISO/IEC14443 anti-collision procedure, the 7 bytes which are part of the 96-bit are sent back by the transponder IC. The EM4423 offers two non-volatile memories which are accessible by both RF air interfaces. The two memories are segmented to implement multiple applications. Each chip is delivered with a preprogrammed 96-bit EPC encoding supporting Multi-vendor Chipbased Serialization (MCS). EM4423 supports the optional BlockWrite command, enabling the fast encoding of a 96-bit EPC. EM4423 also supports the optional Untraceable command to hide portions of memory of the tag or label.
