Product details
Overview
NHS3100/A1Z from NXP Semiconductors is an NFC-enabled, ultra-low-power Arm Cortex-M0+ microcontroller optimized for autonomous temperature monitoring and logging. It integrates an on-die temperature sensor (±0.3 °C accuracy from 0 °C to +45 °C), NFC/RFID ISO 14443 Type A interface, 32 kB flash, 8 kB SRAM, and supports dual power modes-battery (1.72–3.6 V) or NFC-field powered. It targets cold-chain validation tags and disposable sensor labels.
For engineers reviewing the NHS3100/A1Z datasheet, NHS3100/A1Z pinout, NHS3100/A1Z application, or NHS3100/A1Z equivalent, key selection criteria include NFC-powered wake-up capability, battery-off mode current (<50 nA), software-configurable GPIO with high-current sink (20 mA), I²C and SPI peripheral support, and Arm SWD debug compatibility.
Technical Context
The NHS3100/A1Z implements a fully programmable Arm Cortex-M0+ core running at up to 8 MHz (configurable down to 62.5 kHz), paired with a dedicated power management unit (PMU) enabling five distinct power states-including battery-off mode with <50 nA retention current. Its analog subsystem includes a factory-trimmed temperature sensor with ±0.3 °C absolute accuracy in the 0–45 °C range and integrated 32 kHz timer oscillator for RTC functionality.
Dual clock architecture separates system timing (8 MHz internal RC oscillator, ±2 % trimmed) from always-on timing (32.768 kHz FRO), ensuring reliable wake-up and low-power operation. The PMU autonomously selects between VDDBAT and NFC-field power sources, with priority given to battery when both are present and >1.72 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+ with NVIC, SWD debug, and system tick timer-enables firmware customization and real-time interrupt handling. |
| Temperature Accuracy | ±0.3 °C (0 °C to +45 °C); ±0.5 °C outside that range-supports medical-grade cold-chain compliance without external calibration. |
| Power Modes | Five states: Active, Sleep, Deep-sleep, Deep power-down, Battery-off-with <50 nA current in battery-off at 3.0 V for multi-year shelf life. |
| Memory | 32 kB flash (in-system programmable), 4 kB EEPROM (320 B write-protected), 8 kB SRAM-sufficient for firmware, sensor logs, and secure configuration storage. |
| NFC Interface | ISO/IEC 14443 Type A, NFC Forum Type 2 certified (ID 58516)-enables contactless readout of temperature logs via smartphones or readers without batteries. |
| I/O Capability | 12 GPIO pins with configurable pull-up/down, repeater mode, and edge/level interrupts; four pins support 20 mA sink-drives LEDs or small actuators directly. |
| Supply Range | 1.72 V to 3.6 V battery input; also operates solely from NFC field-eliminates need for external power in passive tag applications. |
Pinout & Package
Package: HVQFN24 (SOT616-3), 4 × 4 × 0.85 mm, thermally enhanced, leadless quad flat. Pin functions are software-configurable via IOCON registers; physical pad allocation follows Table 3 and Table 4 of Rev. 8.03 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDBAT (Pad 7) | Primary supply input | Accepts 1.72–3.6 V battery; powers internal LDOs when active and prioritized over NFC source. |
| VSS (Pad 8, 25) | Ground reference | Dual ground pads ensure low-impedance return path for analog and digital domains; Pad 25 must be tied to ground. |
| LA / LB (Pads 19, 20) | NFC antenna terminals | Direct connection points for external loop antenna; require impedance-matched layout per NFC design guidelines. |
| PIO0_0/WAKEUP (Pad 1) | Deep power-down wake source | Configurable as GPIO or hardware wake trigger; requires 100 μs LOW pulse to exit deep power-down mode. |
| RESETN (Pad 9) | Active-low reset input | Resets CPU and peripherals to default state; features weak internal pull-up to highest available voltage (VDDBAT or NFC). |
| PIO0_4/SCL & PIO0_5/SDA (Pads 11, 12) | I²C bus interface | Open-drain, no internal pull-up; supports 400 kbit/s fast-mode I²C for connecting external sensors or EEPROMs. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar temperature-monitoring-with-NFC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV64K | Dedicated NFC EEPROM with integrated temperature sensor (±1 °C); no MCU, no programmable logic, no flash memory. | Limited to basic temperature logging; cannot run custom firmware, process data, or support I²C/SPI peripherals. | Select when only passive, fixed-function logging is needed and firmware flexibility is unnecessary. |
| ATSHA204A + ATtiny412 | Discrete security IC + ultra-low-power MCU; requires external temperature sensor, NFC transceiver, and power management. | Higher BOM count and PCB area; enables full custom firmware but lacks integrated NFC antenna interface and single-chip thermal calibration. | Select when cryptographic authentication or complex sensor fusion is required beyond NHS3100/A1Z's integrated capabilities. |
Compared with ST25DV64K and ATSHA204A+ATtiny412, NHS3100/A1Z uniquely combines Arm-based programmability, factory-calibrated temperature sensing, NFC interface, and sub-50 nA battery-off current in a single HVQFN24 package-reducing system complexity and qualification effort for regulated thermal logging.

FAQ
What power sources does the NHS3100/A1Z support?
The NHS3100/A1Z supports dual power modes: external battery (1.72–3.6 V applied to VDDBAT) and passive NFC-field powering. Its integrated PMU automatically selects the source, prioritizing battery when both are present and valid. In NFC-only mode, it draws energy directly from the RF field to operate the temperature sensor, memory, and NFC interface-making NHS3100/A1Z suitable for truly battery-free applications.
Does the NHS3100/A1Z include a calibrated temperature sensor?
Yes, the NHS3100/A1Z integrates a factory-calibrated on-die temperature sensor with ±0.3 °C absolute accuracy from 0 °C to +45 °C, ±0.5 °C from −40 °C to 0 °C and +45 °C to +85 °C. Calibration data is stored in OTP memory, and readings are accessible via firmware or NFC commands-no external calibration or compensation is required for NHS3100/A1Z to meet cold-chain accuracy standards.
Can the NHS3100/A1Z be programmed with custom firmware?
Yes, the NHS3100/A1Z features an Arm Cortex-M0+ core with 32 kB flash and 8 kB SRAM, supporting standard Arm toolchains (Keil, GCC, IAR). Firmware is loaded via SWD using the SWCLK/SWDIO pins (Pads 15/16), and the device is fully debuggable. This allows full customization of logging intervals, NFC data structure, sensor fusion, and wake-up logic-unlike fixed-function alternatives.
What is the lowest power state of the NHS3100/A1Z and its current draw?
The lowest power state is battery-off mode, where NHS3100/A1Z consumes <50 nA at 3.0 V while retaining critical state in GPREGx registers within the always-on domain. This mode disables all clocks, peripherals, and LDOs except the trigger detector and power gate-enabling decade-scale shelf life before first use, a key requirement for NHS3100/A1Z in disposable sensor applications.
Is the NHS3100/A1Z NFC Forum certified?
Yes, the NHS3100/A1Z is NFC Forum Type 2 certified with certification ID 58516 (as of September 22, 2017). It complies with ISO/IEC 14443 Type A and supports standard NDEF message formatting, ensuring interoperability with all NFC-enabled smartphones and readers without proprietary drivers-critical for NHS3100/A1Z deployment in consumer-facing and logistics environments.
