Passive RFID IC EM4124

EM4124,Read/Write, EPC Gen2 / ISO 18000-63 Type C Passive RFID IC

EM4124 is a certified EPCTM Class-1 Generation-2 (Gen2) IC and compliant with ISO/IEC 18000-6:2010 Type C. Each chip is manufactured with a 64-bit Unique Identifier to ensure full traceability.

The EM4124 has 176 bits of non-volatile memory (16 bit PC Word, 96 bit EPC Code, 32 bit Kill Password and 32 bit Access Password), enabling the support of ISO or EPC data structures.

EM4124 achieves a typical read sensitivity of -19 dBm at the chip level, which translates into a typical -21 dBm sensitivity at the tag level for a dipole-like antenna with 2 dBi gain (25us TARI, 250 kHz BLF).

EM4325

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 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 1.8, and is delivered with a Unique Identifier (UID) to ensure full traceability.

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.

What is EPC Gen 2?

What is EPC Gen 2?
Gen 2 is the shorthand name given to the second generation EPC global protocol. It addressed the compatible problems in old tag class 0 and 1 and was designed to be globally accepted with enhancements such as a dense reader mode of operation, so as to prevent readers from interfering with one another when they are used in close distance to each other. It was later adopted with minor adjustments as ISO 18000-6C.
