Product data sheet
1 General description
The NHS3152 is an IC optimized for therapy adherence monitoring and logging. It
has an embedded NFC interface, a resistive network sensing-interface, an internal
temperature sensor, and a direct battery connection. These features support an effective
system solution with a minimal number of external components and a single layer foil
implementation for pill usage monitoring. The NHS3152 works either battery-powered or
NFC-powered.
The embedded ARM Cortex-M0+ offers flexibility to the users of this IC to implement
their own dedicated solution. The NHS3152 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 NHS3152 with the industry-wide standard solutions for ARM
Cortex-M0+ processors.
As of September 25, 2017, this device has been certified by the NFC forum (certification
ID: 58524).
CAUTION
Semiconductors are light sensitive. Exposure to light sources can cause the IC to
malfunction. The IC must be protected against light. The protection must be applied to all
sides of the IC.
CAUTION
msc896
This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling
electrostatic sensitive devices.
Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A or
equivalent standards.
