Detailed product information
EM4325 is a Class-3 Generation-2 (Gen2) IC that is compliant with ISO/IEC 18000-63 (Gen2) & ISO/IEC 18000-64 (TOTAL) as well as EPCTM Class-1 Generation-2. The chip can be used either in passive mode or in battery assisted passive (BAP).
EM4325 supports advanced applications by providing programmable external interfaces for an auxiliary function and a 4-bit I/O port which may be configured as an input for tamper detection or as an output for notification of RF events to external devices. It may be configured to support a Serial Peripheral Interface (SPI) bus. The chip may serve as either an SPI Master device or an SPI Slave device.
EM4325 implements temperature sensor and data logging capability for cold chain temperature monitoring application.
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.
Smart battery supply management is provided to extend battery life in BAP applications.
