| General description |
EM4324 is a long range passive / battery-assisted UHF RFID tag IC compliant with the ISO 18000-6C / EPCglobal Class-1 Generation-2 protocol. The chip offers an advanced feature set (EPC+) leading to a performance beyond that of standard Gen2 chips. Battery-assisted, EM4324 offers superior reading range and reliability compared to purely passive RFID solutions. The battery- assisted mode is tailored to harsh environment applications where other passive UHF solutions fail e.g. in the presence of water or metal.
The EM4324 current consumption has been optimized to maximize battery lifetime. Even if the battery is flat, the chip continues to operate and communicate with the reader in passive mode.
The memory size is 1024 bits enabling support of ISO or EPC data structures. Each chip is delivered with a 64-bit Unique Identifier to ensure full traceability.
The EM4324 includes a tamper detection circuit to support E-seal applications. Tamper detection can be implemented using a simple continuity loop, with heat sensitive fuse wire, with sensors having both high and low impedance states, or with external devices controlling an electronic switch such as a MOSFET.
