Abstract: A method for near field communication with a serial transmission microcontroller and an NFC tag device using the same are provided in the present invention. The method includes: providing a serial interface microcontroller; capturing an NFC carrier signal from an NFC LC resonant circuit; performing a frequency division to the NFC carrier signal to obtain a NFC clock signal; filtering the NFC carrier signal from the NFC LC resonant circuit to obtain an envelope signal; sequentially receiving a digital sequence of the envelope signal according to triggering of the NFC clock signal based on a serial transmission protocol; and decoding an NFC data from the digital sequence based on an NFC transmission protocol rule.
