13.56MHz NFC Transceiver IP
The IP is NFC Transceiver AFE which includes microcontroller and memories integration, power management unit, clock management unit, peripheral interfaces, analog frontend.
In addition, implemented first stage bootloader firmware (stored in ROM) which initializes minimal necessary parts of the system and loads actual firmware from Flash memory.
The IP contains ALM block, performs modulation by actively transmitting signal of an inversed polarity to suppress reader’s signal thus enlarging AM depth. Long ALM sequences have recovered clock between the modulation pulses, so it can remain locked thus enriching tag emulation distance range.
In case implemented IP connection is done via NFC Controller Interface (NCI, software defined in NFC Forum). NCI is mapped to one of physical interfaces (I2C, SPI, UART).
