EM Microelectronic introduced the EM4094, an analog front-end integrated circuit for 13.56MHz RFID readers. This IC was designed to accommodate a wide range of microcontrollers (MCU) and multiple communication protocols. It is well suited for use in low-cost or handheld reader solutions. In addition to the IC, EM Microelectronic also introduced the EMDB408 13.56MHz RFID Demonstration Reader as a reference design and development tool kit.

The EM4094 can be operated between 3Vdc to 5Vdc supply voltage with output power up to 200mW. It integrates an 848kHz BPSK decoder which allows the reader manufacturer to select a cost effective MCU. The IC can be used in a range of reader systems with sub-carrier frequencies between 212kHz and 848kHz. It covers the ISO14443 A and B, Sony FeliCa or ISO15693 standards and operates with NFC devices.

The EM4094 RFID Demonstration Reader reference design is a 13.56MHz RFID reader that is compliant with the ISO14443 type A and B, Sony FeliCa and the ISO15693 standards supporting all mandatory commands. The demo reader also supports mandatory, optional, custom and proprietary commands of EM Microelectronic's transponder ICs: the EM4034, EM4035, EM4135 and the EM4006 read-only IC. The development tool kit serves as a reference design for reader manufacturers; it comes with a fully functional reader, 7.5V AC/DC power supply, EM4034 and EM4035 tags in credit card format, a SIM card with cryptographic functions, USB cable and CD ROM.

Both the EM4094 IC and EMDB408 RFID demo reader are available now. Pricing for the EM4094 starts at $2.65 each in quantities of 1,000 pieces.
