Description

The overall scope of this reference design is to provide a contactless service interface. Service interfaces allow reading logs from the system and configuring system (calibration data, firmware upgrades, etc.) in factory applications such as Human Machine Interface (HMI). FRAM content on an ultra-low-power MSP MCU available over NFC and serial port (I2C, SPI) simultaneously, enables log messages to be read, by a temperature or pressure transmitter as an example, even when the system is without power. Configuration parameters can also be programmed at commissioning before (or after) the system is installed and powered. With such a function the system does not need to be powered to be configured or to read their logs, this brings significant cost savings at commissioning or in quality returns.

Features
  • ISO14443B interface (RF430CL330): Android NFC standard
  • 64kB FRAM (MSP430FR5969)
  • Up to 8Mb/s throughput to/from FRAM over serial
  • 800kb/s throughput to/from FRAM over NFC
  • Powered over NFC
  • Power ORing is provided between the main system and the NFC daughter card to demonstrate that the NFC card can be woken up when the main system is down.
