Multiplexing was developed in the early 1870s, but it’s become much more applicable to digital telecommunications in the late 20th century. Today, frequency division multiplexing (FDM), time division multiplexing (TDM), and wavelength division multiplexing (WDM) have become an extremely important asset to telecommunication processes and has greatly improved the way that we transmit and receive independent signals over AM and FM radio, telephone lines, and optical fibers.

Texas Instruments (TI) released today the industry’s first Near Field Communication (NFC) sensor transponder family. The RF430RL25xH system-on-chip (SoC) device is equipped with a fully programmable low power microcontroller (MCU), non-volatile FRAM, an analog-to-digital converter (ADC) and supports an ISO 15693-compliant NFC interface as well as Serial Peripheral Interface (SPI) and Inter Integrated Circuit (I2C). The high frequency13.56-MHz sensor transponder can operate on full passive (battery-less) or semi-active modes for optimal battery life in portable and wireless sensing applications.
