E-Paper label with NFC link

The reference design contains a NFC link to a PDA or Android smartphone. The magnetic energy of the NFC reader / writer of the Android phone is high enough to supply the reference PCB with MCU and E-Paper label. The PCB holds a System on Chip (NFC antenna interface, embedded MCU, EEprom and SPI interface), a further MCU and the E-paper label. The E-Paper label is connected with the main MCU by SPI. The text string will be forwarded wireless from the smart phone to the E-Paper on the reference PCB. The whole application does not need a battery or power supply, because the power is delivered by the magnetic field of the NFC antenna. If you have 38 seconds left, then have a look on the Youtube video.

Applications for the NFC interface

The NFC SoC is ideal for applications like passive wake-up, multipurpose RF interface to a micro controller, low power or passive programming, ultra low power data logger, RFID programmable configuration EEPROM, ISO 14443A smart card, NFC Forum Tag Type 4, and Bluetooth and Wi-Fi pairing.
If you plan an own wireless application around a smartphone (e.g. NFC, Classic Bluetooth, Bluetooth Low Energy or WI-Fi) and need advice, consulting, prototyping or development then do not hesitate to drop an email to harald.naumann (at) gsm-modem.de
