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.

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
