FACT SHEET | EM4325 Subject to change without notice 4325-FS2, Version 1.1, 25-May-15 Copyright © 2015, EM Microelectronic-Marin SA www.emmicroelectronic.com EM4325 Coin Cell Reference Design General Description Theoretical RF Sensitivity and Read Range The EM4325 Coin Cell Reference Design is an easy interface to get started with the multi-purpose EPC gen2 IC EM4325. It provides an easy way to demonstrate three specific use cases with a very small tag form factor (38mm of diameter). There are Parameter 1) Passive tag with temperature reading on demand 2) Passive tag with tamper detection and temperature reading on demand 3) BAP tag with tamper detection, temperature monitoring, and alarm indicators Starting from these three simple examples, the gerber file can be quickly adapted to fit the other application use cases of the EM4325. Frequency (MHz) 867 915 IC Sensitivity (dBm) -28.0 -28.0 Inlay Sensitivity (dBm)* -18.55 -17.7 Read Range (EU / NA)* 24.3’ (7.4m) 29.3’ (8.9m) *Theoretical inlay sensitivity and read range for the 0.010" reference antenna design. Option Available A complete design documentation and the production gerber files are available on the EM website under the support page of the EM4325 for free. Two options are available on request.
