TIDA-00217
Dynamic Field-Powered NFC for Data Logging Access Control & Security Applications Reference Design
TIDA-00217
Overview
This reference design is a sub-system design for NFC (Near Field Communication) and authentication. This subsystem design is intended as a reference design for part authentication, access control, personal identification, battery-less sensor interface, security token transfer, and low power transfer of local data. In many systems, especially safety critical applications, it is imperative that only authentic, inspected, and properly maintained parts are utilized. The documentation describes the implementation of a subsystem capable of storing such information and communicating this data to the outside world by way of NFC or I2C/SPI/UART to a connected host controller. This reference design provides an easy method for wireless data and power transfer to any standard NFC compliant device.
Features
- RF430CL330H Dynamic NFC Transponder enables static tag emulation
- NFC Type 4B Compliant
- NFC/RFID Protocol Handled in ROM Code
- Passive or Active Operational Modes allows for data extraction even if a system loses power
- MSP430FR5969 Ultra-Low-Power FRAM Microcontroller
- 100uA/MHz Active Current, 450nA Standby Current w/ RTC
- FRAM enables quicker and lower-power writes
- Security features like AES and IP Encapsulation minimize cycles and protect information
- Wireless Sensor Interface
- Uses Either Field or Bus Power
