Microcontroller

The MLX90121 is an ISO compliant 13.56MHz RFID transceiver integrated circuit.

The main features include user selectable modulation depth in write mode, whereas single sub-carrier, FSK and PSK modulations are recognized in the read mode.

The receiver is based on a diode envelope detector, followed by an IF filter and amplifier. A logarithmic amplifier is used for single subcarrier detection, ensuring fast and clean data recovery. The limiting output of the log amp is used for FSK and PSK recovery.

The transmitter uses a built in open drain output transistor, which can provide up to 250 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.
