The EM4325 from EM Microelectronic is a Gen2 RFID IC that is compliant with ISO/IEC 18000-63 and ISO/IEC 18000-64 (TOTAL). The chip can be either battery powered or beam powered by the RF energy transmitted from a reader. It 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 1.10, and is delivered with a Unique Identifier (UID) to ensure full traceability. It supports programmable duty cycle control, auto-switching between a battery powered and beam powered operation, and programmable enable/disable of an ultra-low power mode for extended storage applications. It is ideal for RFID tags and RFID front end for embedded applications.
The EM4325 supports advanced applications by providing programmable external interfaces for an auxiliary function and a 4-bit I/O port. 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 an SPI Master with energy harvesting and provide power to external components. The chip has an integrated temperature sensor and supports the temperature range from -40°C to +60°C.
