EM4325 - UHF Gen2 Battery Assisted Passive RFID IC w/Temp Sensor & SPI Interface


EM4325 is a Class-3 Generation-2 (Gen2) IC that is compliant with ISO/IEC 18000-6:2010 Type C and Type D (TOTAL) as well as EPCTM Class-1 Generation-2. The chip offers an advanced feature set leading to a performance beyond that of standard Gen2 chips and can be either battery powered or beam powered by the RF energy transmitted from a reader. In a battery assisted passive (BAP) configuration, the EM4325 offers superior reading range and reliability compared to purely passive RFID solutions.

EM4325 includes 4096 bits of high speed non-volatile memory (EEPROM) that is organized into 64 pages with 4 words per page. The chip supports either ISO or EPCTM data structures that are compliant with EPCglobal Tag Data Standards, Version 1.6, and is delivered with a Unique Identifier (UID) to ensure full traceability. 

An integrated temperature sensor is included in the EM4325 and supports the temperature range from -40C to +64C. The temperature sensor may be used in either purely passive or BAP applications. Temperature readings can be made on demand by a reader or the chip may be programmed to perform self-monitoring with alarm conditions. The temperature sensor may also be configured to provide Simple Sensor Data reporting using temperature sensor formats defined in ISO/IEC 18000-6:2010. 

EM4325 supports advanced applications by providing programmable external interfaces for an auxiliary function and a 4-bit I/O port. The auxiliary function may be configured as an input for tamper detection or as an output for notification of RF events to external devices. The 4-bit I/O may be configured to support 4 discrete signals or as a Serial Peripheral Interface (SPI) bus. The chip may serve as either an SPI Master device or an SPI Slave device. The programmable external interfaces allow the EM4325 to function as an RF front end and protocol handler in advanced RFID tags or embedded applications. In a passive configuration, the programmable external interfaces allow the EM4325 to serve as a SPI Master with energy harvesting and provide power to external components.

Battery supply management is provided to prolong battery life in BAP applications. The chip supports programmable duty cycle control, auto-switching between battery powered
and beam powered operation, and programmable enable/disable of an ultra-low power mode for extended storage applications.

!D Gate

The !D Gate is a modern, open pedestal that is mounted on the floor. Because it is an integrated reader, both the reader and antennae are included. It supports processes like goods receiving, transition from stock room to sales floor and anti-theft (EAS). Depending on the role, the optimum RFID parameters are chosen automatically.

!D Hand 2 - RAIN RFID handheld reader

The !D Hand 2 is Nedap’s 2nd generation RAIN RFID handheld reader, especially designed for in-store retail applications. Its high reading performance in combination with its intuitive, fashionable design make it the ideal device for store staff to work with.

!D POS

The !D POS is an integrated reader to be used for reading items at the point-of-sale station. It has a small, rugged casing that can be mounted under the cash desk. The antenna only reads items on top of the reader, while ignoring items below or next to the antenna, due to the built-in shielding. It can be connected via USB or Ethernet, while the power can be supplied by a local power supply.

!D Top

The !D Top is a state-of-the-art integrated reader that can easily be mounted on the wall or to the ceiling - using almost invisible steel cables. Its elegant, compact design blends into every store, keeping the entrance of the store or the passage to the stock room wide open. At the store entrance, the !D Top can be used stand-alone as RFID-based EAS system or used as an addition to existing traditional EAS systems.
