Rockchip has announced at COMPUTEX Taipei that it has launched the world lowest power WiFi technology RKi6000 jointly developed with a third party. This technology makes WiFi power consumption equal to that of BT4.0 LE (Low Energy). The receiving power consumption is around 20mA during use, which is 85% lower than state-of-the-art WiFi devices for the Internet of Things (IoT), setting a benchmark power consumption level that should renew the standard for WiFi power consumption in IoT smart hardware globally.

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.
