Texas Instruments Incorporated has announced its development of the near field communications (NFC) transceiver with the lowest power, changing the way the industry looks at ultra-low-powered contactless short-range communication.
When compared to the competition, this new device, called the TRF7970A, extends the life of the battery up to twice as long. This is because it provides the user with eight power mode options, ranging from
The transceivers have software that is easy-to-configure, so that developers can rapidly begin their work. Developers are also capable of accessing all of the control registers directly, so that for simple tweaking of numerous parameters to allow for the best possible performance for all of the applications.
The current platform for the TRF7970A NFC includes:
• The lowest power NFC transmitter in the industry
• Support for the crystal oscillator frequencies (13.56 MHZ and 27.12 MHz) which allows for more speed flexibility for engineers and more design cost options.
• A wide range of supported communication options, allowing for peer-to-peer communication, as well as card emulation, and capability for reader/writer.
• NFC software stack libraries with a new detector for RF fields which permits ease of development and designs that are strong yet cost effective.
• NFC Peer-to-PEER Initiator and a Passive and Active Target Operation within the MSP430 microcontrollers.
• A significant FIFO buffer at 128 bytes for NFC transactions, permitting microcontroller-using developers who have small MHz to build products that can handle sizeable transfers of data.
• ISO/IEC 18092 and ISO/IEC 21481 standards compliance so that developers can create products that will operate globally.
• Multiple reader/writer protocol support.
