NHS3100: NTAG SmartSensor with Temperature Sensor and Digital IOs

Overview

The NXP NHS3100 is an IC optimized for temperature monitoring and logging. With its embedded NFC interface, internal temperature sensor and direct battery connection, it supports an effective system solution with a minimal number of external components.

The embedded Arm^® Cortex^®-M0+ offers flexibility to the users of this IC to implement their own dedicated solution. The NHS3100 contains multiple features, including multiple Power-down modes and a selectable CPU frequency of up to 8 MHz, for ultra-low power consumption.

Users can program this NHS3100 with the industry-wide standard solutions for Arm Cortex-M0+ processors.
