MLX12115

The MLX12115 is an ISO compliant 13.56MHz

RFID transceiver integrated circuit.

It can be used as a drop-in replacement of

Texas Instruments’ S6700. The device supports

multiple RF air interfaces, such as Tag-it™

ISO15693 and ISO14443A

the direct mode where data can be passed

directly to a transponder.

Package Code

Page 1

The main features include user selectable

modulation depth in write mode, whereas single

sub-carrier ASK and FSK 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 milliwatts 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,

applications.

The chip is configured with a serial interface. A

synchronization signal is available when the

majority voting is used.
