Certified security is combined with a tamper status detection mechanism and battery-free sensing in the NTAG 22x DNA StatusDetect IC family by NXP. The ICs measure a change in ambient conditions, such as moisture, liquid fill level or pressure and allow developers to combine secure authentication with opening status detection or condition monitoring of products to help maintain a secure supply chain and product integrity.

Evaluation board verifies battery management for the IoT
To verify operation of battery management in electronic devices such as wearables, industrial IoT products, such as smart cards and electronics shelf labels as well as portable devices, Rohm has developed the REFLVBMS001-EVK-001.
Sensor Watch pares down connectivity to add functionality
Crowd Supply has added an Arm Cortex M0+ to the classic Casio wristwatch to produce the Sensor Watch. According to Crowd Supply, it forsakes power-hungry features like Wi-Fi connectivity, Bluetooth support and a huge screen, focusing instead on 1990s nostalgia-styling, practical applications and battery life.
Step-down buck converter is for multi-cell batteries
Single stage power conversion in multi-cell battery applications is provided with the MAX77540 step-down buck converter. Examples of use are AR / VR headsets, land mobile radios and digital single-lens reflex (DSLR) cameras. The power-dense MAX77540 buck converter features 94 per cent peak efficiency and wafer level packaging that measures 61 per cent smaller than traditional quad flat no-lead (QFN) packages.
