Product details
Overview
NHS3100UK/A1Z from NXP Semiconductors is an NFC-enabled, ultra-low-power temperature monitoring IC with embedded Arm Cortex-M0+ processor, integrated ±0.3 °C accurate temperature sensor (0 °C to +45 °C), 32 kB flash, and dual power capability (1.72–3.6 V battery or NFC field). It enables standalone, battery-free temperature logging in cold chain validation and disposable sensor tags.
For engineers reviewing the NHS3100UK/A1Z datasheet, NHS3100UK/A1Z pinout, NHS3100UK/A1Z application, or NHS3100UK/A1Z equivalent, this page delivers verified package mapping (WLCSP25), confirmed I²C/NFC/temperature sensor functionality, validated deep power-down current (<50 nA), and two documented alternative parts for temperature-sensing NFC SoCs.
Technical Context
The NHS3100UK/A1Z integrates an Arm Cortex-M0+ core running at up to 8 MHz with NVIC, SWD debug, and system tick timer, alongside dedicated analog blocks including a factory-trimmed temperature sensor with ±0.3 °C accuracy over 0–45 °C and a 32 kHz RTC oscillator. Its power architecture supports automatic source selection between VDDBAT and NFC rectified voltage.
It implements four reduced-power modes-sleep, deep-sleep, deep power-down, and battery-off-with <50 nA current draw in battery-off mode at 3.0 V, and features programmable power gating per analog peripheral. The I²C interface operates at 400 kbit/s with open-drain SCL/SDA pins, and NFC compliance is certified to NFC Forum Type 2 (ID: 58516).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC-enabled temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV64K | EEPROM-based NFC tag with external temperature sensor interface (I²C); no embedded MCU or local processing | Lacks onboard computation, logging autonomy, or RTC; requires host MCU for data processing and scheduling | Select when only passive NFC readout of pre-recorded values is needed; not suitable for autonomous logging or firmware customization |
| INFINEON SLB9670 | Trusted Platform Module (TPM) with integrated temperature sensor; focused on cryptographic security, not ultra-low-power logging | Higher active current (>1 mA), no battery-off mode; designed for secure boot, not environmental monitoring | Choose only when cryptographic attestation of temperature data is required; unsuitable for long-term unattended logging |
Compared with ST25DV64K and INFINEON SLB9670, NHS3100UK/A1Z uniquely combines autonomous temperature logging, sub-50 nA battery-off operation, and user-programmable Arm Cortex-M0+ firmware - enabling fully self-contained, smartphone-readable smart sensor tags without external controllers.

FAQ
What is the temperature accuracy specification of the NHS3100UK/A1Z across its full operating range?
The NHS3100UK/A1Z features a factory-trimmed internal temperature sensor with ±0.5 °C absolute accuracy from −40 °C to 0 °C, ±0.3 °C from 0 °C to +45 °C, and ±0.5 °C from +45 °C to +85 °C. These values are measured and guaranteed per the Rev. 8.03 datasheet and apply directly to the NHS3100UK/A1Z in its WLCSP25 package without external calibration.
Does the NHS3100UK/A1Z support both battery-powered and NFC-powered operation simultaneously?
No - the NHS3100UK/A1Z uses an automatic source selector that prioritizes VDDBAT when >1.72 V is present; NFC power (VNFC) is used only when VDDBAT is absent or below threshold. Both sources cannot power the IC concurrently, but seamless switchover is supported in either direction without reset or data loss in the NHS3100UK/A1Z.
How many GPIO pins does the NHS3100UK/A1Z provide, and what configuration options are available?
The NHS3100UK/A1Z provides 12 GPIO-capable terminals (PIO0_0 through PIO0_11) in its WLCSP25 package. Each pin supports software-defined function (GPIO or peripheral), configurable pull-up/pull-down resistors or repeater mode, and hysteresis control via the IOCON register block - all confirmed for the NHS3100UK/A1Z in Section 7.2 and 8.6 of the datasheet.
Is the NHS3100UK/A1Z NFC Forum certified, and what is its certification ID?
Yes - the NHS3100UK/A1Z is NFC Forum Type 2 certified with ID 58516, as documented in the Rev. 8.03 product data sheet dated 27 May 2021. This certification ensures interoperability with all NFC Forum–compliant smartphones and readers for reliable, standards-based data access to the NHS3100UK/A1Z.
What is the minimum current consumption of the NHS3100UK/A1Z in battery-off mode?
The NHS3100UK/A1Z draws less than 50 nA in battery-off mode at 3.0 V, as specified in Section 2.7 of the datasheet. This ultra-low quiescent current enables multi-year shelf life prior to activation and is a guaranteed parameter for the NHS3100UK/A1Z WLCSP25 variant.
