| MLX12115 13.56MHz RFID Transceiver Features and Benefits Conforms with ISO/IEC 14443A Conforms with ISO/IEC 15693 Compatible with Tag-itTM(2) transponders Low external component count (1) Applications Portable data terminals Access control readers Contact-less payment terminals Smart label printers Ordering Information Part No. MLX12115 Temperature Suffix E (-40 to 85 C C) Package Code FR (Lead free SSOP20, 2 09 mils) Option code -- 1. Functional Diagram Attenuation resistor RX TX Impedance matching Analog functions MLX12115 The main features include user selectable modulation depth in write mode, whereas single sub-carrier ASK, FSK and PSK modulations are recognized in the read mode. Its low power consumption enable design of portable and fixed reader designs requiring tight footprint constraints. The IC minimizes onboard power requirements and reduces parts count in a final reader product. With the addition of a micro-processor, crystal, and a few passive components a full functioning reader can be easily developed. It can provide up to 200 miliwatts of RF power to a 50 ohms load with a 5 volts power supply using the recommended matching network. This is suitable for most short to mid range applications. A simplified antenna and matching network can be used, at the expense of a reduced reading range, for example in hand-held reader applications. The chip is configured with a serial interface. A synchronization signal is available when the majority voting is used. Digital functions Serial data interface Microcontroller 2. Description The MLX12115 is an ISO compliant 13.56MHz RFID transceiver integrated circuit. It could be used as a drop-in replacement of Texas Instruments' S6700. The device supports (2) multiple RF air interfaces, such as Tag-itTM , (1) ISO15693 and ISO14443A and opens with the direct mode where data can be passed directly to a transponder. Purchase of MLX12115s doesn't imply any grant of any ISO14443A license. Customers are advised to sign patent licensing agreements with all third parties, especially those companies listed in the introduction of the corresponding standard. (2) (1) Purchase of MLX12115s doesn't imply any grant of any Tag-itTM license. Customers are advised to sign patent licensing agreements with Texas Instruments. Tag-itTM is a trademark of Texas Instruments Incorporated 3901012115 Rev. 001 Page 1 Fact Sheet Jan-2007 |
