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 Cortex-M0+ processors.
