NFC + I2C combo device is a passive solution for NFC interaction with electronic devices

NXP’s NTAG I2C solution enables feature-rich options on home appliances and wearable devices – as well as the ability to power itself. The NTAG’s I²C memory can be accessed via the existing embedded microcontroller of any electronic device.


Turning off the tick in the RTOS cuts MCU power consumption

Segger has added tickless low power support to its embOS real time operating system. The tickless low power feature reduces the power consumption for battery powered devices; it stops the periodic system tick interrupt during idle periods. Instead of having a timer interrupt for each system tick the timer is reprogrammed to be able to spend as much time as possible in low power mode.


FRAM microcontroller range grows for metering, health/fitness and wearables designs

Texas Instruments has added to its ferroelectric RAM MCUs with the ultra-low-power MSP430FR69x that has integrated smart analogue, extended scan interface, LCD controller and up to 128 kB memory.
