2 Description

The MLX90109 is a single chip RFID transceiver

for the 125kHz frequency range.

conceived for minimum system cost and minimum

power consumption, offering all required flexibility

for a state of the art AM transceiver base station.

An external coil (L), and capacitor (C) are

connected as a parallel resonant circuit, that

determines the carrier frequency and the oscillator

frequency of the reader.

modulation effects by perfect antenna tuning, and

avoids the need for an external oscillator.

The reader IC can easily be switched to power

down by setting the antenna amplitude to zero.

The MLX90109 can be configured to decode the

transponder signal on-chip.

decoded signal is available through a 2-wire

interface with clock and data.

interface wiring, the non-decoded transponder

signal can also be made available on a single wire

interface.
