Product details
Overview
NHS3152UK/A1Z from NXP Semiconductors is a therapy adherence resistive monitor IC integrating an Arm Cortex-M0+ processor, NFC/RFID ISO 14443 Type A interface, six-channel analog I/O with temperature sensor (±0.3 °C accuracy from 0 °C to +45 °C), and ultra-low-power operation down to <50 nA in battery-off mode - designed for single-layer foil pill-bottle or blister-pack usage logging.
For engineers reviewing the NHS3152UK/A1Z datasheet, NHS3152UK/A1Z pinout, NHS3152UK/A1Z application, or NHS3152UK/A1Z equivalent, this page delivers verified specifications, WLCSP25 package mapping, NFC-powered vs. battery-powered operational modes, and real-world therapy monitoring use cases - all grounded in NXP's Rev. 5.02 product data sheet.
Technical Context
The NHS3152UK/A1Z implements a dual-power architecture with automatic source selection between VDDBAT (1.72–3.6 V) and NFC-field-derived power, enabling passive and active operation without external regulators. Its Arm Cortex-M0+ core runs at up to 8 MHz (with programmable clock dividers down to 62.5 kHz) and includes NVIC, SWD debug, and system tick timer.
Analog subsystem integration includes a flexible on-chip analog switch matrix routing six AN0_x pins to shared ADC/DAC/CDC converters via time-division multiplexing, plus dedicated temperature sensing with ±0.3 °C accuracy over the clinical range (0 °C to +45 °C). Power management supports five discrete states: Active, Sleep, Deep-sleep, Deep power-down, and Battery-off - each with domain-specific LDO control (1.2 V and 1.6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+ running up to 8 MHz - enables firmware-defined therapy logic and local decision-making without host MCU. |
| Memory | 32 kB flash + 8 kB SRAM + 4 kB EEPROM (320 B write-protected) - sufficient for secure log storage and firmware updates in constrained medical edge devices. |
| NFC Interface | ISO 14443 Type A, NFC Forum Type 2 certified (ID 58524) - enables tap-to-read compliance data without batteries or connectors. |
| Temperature Sensor | ±0.3 °C absolute accuracy from 0 °C to +45 °C - meets clinical-grade thermal validation requirements for medication storage environment monitoring. |
| Power Modes | Five states including Battery-off (<50 nA @ 3.0 V) - extends shelf life of unpowered smart packaging until first NFC activation or battery connection. |
| Analog I/O | 6 configurable analog pins (AN0_0 to AN0_5) routed via on-chip switch matrix to shared ADC/DAC/CDC - supports resistive network sensing for multi-pill blister detection. |
| I/O Pins | 12 GPIO with interrupt capability, 4 high-current sink drivers (20 mA), I²C (400 kbit/s), SPI, and SWD - enables direct foil trace interfacing and debug during development. |
Pinout & Package
Package: WLCSP25 (2.51 × 2.51 × 0.5 mm, SOT1401-1), ball-grid layout optimized for ultra-thin medical packaging integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | VDDBAT | Main positive supply input (1.72–3.6 V); powers digital/analog domains when active and higher than NFC voltage. |
| A2, C3 | VSS | Digital ground reference; dual-ball connection improves low-impedance return path for noise-sensitive analog measurements. |
| A3 | RESETN | Active-low external reset; weak internal pull-up to highest available supply (VDDBAT or VNFC) ensures reliable boot initialization. |
| A4, A5 | SCL / SDA | I²C-bus interface (400 kbit/s fast mode); open-drain configuration supports multi-drop communication with external sensors or controllers. |
| D1 | PIO0_0/WAKEUP | Deep power-down wake-up input; must be pulled LOW ≥100 μs to exit DEEPPDN - used for foil-break or button-triggered event logging. |
| E4, E5 | LA / LB | NFC antenna terminals; differential connection to external coil enables passive RF energy harvesting and bidirectional command exchange. |
| E1–E3, D3, D4, D5 | AN0_0 to AN0_5 | 6 analog I/O pins; software-configurable as inputs to ADC/CDC or outputs from DAC - forms resistive network interface for pill-count verification. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded NFC + Battery Dual-Power Operation | Enables zero-battery shelf life and post-deployment activation via NFC tap - eliminates need for pre-installation battery charging or replacement. |
| Configurable Analog Switch Matrix | Allows time-multiplexed measurement of all six AN0_x pins using single ADC/DAC/CDC instances - reduces silicon area and power vs. per-channel converters. |
| Ultra-Low-Power Battery-Off Mode | <50 nA current draw at 3.0 V preserves shelf life >5 years in unpowered smart packaging - critical for OTC and prescription adherence solutions. |
| On-Chip Temperature Sensing | ±0.3 °C accuracy over 0–45 °C clinical range - validates medication storage conditions without external sensor calibration or BOM cost. |
| Arm SWD Debug Support | Serial Wire Debug (SWCLK/SWDIO on B5/C5) enables in-system firmware update and real-time debugging during device qualification and field deployment. |
Applications
| Smart Pill Bottle Monitoring | Blister-Pack Adherence Tracking |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar therapy adherence monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV64K | NFC EEPROM only (no MCU, no analog sensing, no temperature sensor); 64-kbit memory; I²C + RF interface. | Limited to passive data storage; cannot execute custom logic, perform resistive sensing, or log temperature - requires companion MCU. | Select when only NFC-accessible static data storage is needed; not suitable as standalone adherence monitor. |
| MAX32665 | Arm Cortex-M4F MCU with BLE, 2 MB flash, but no integrated NFC or resistive sensing front-end; requires external NFC chip and analog circuitry. | Supports richer connectivity and processing, but increases BOM count, PCB area, and power consumption - lacks NHS3152UK/A1Z's foil-integration optimization. | Choose for Bluetooth-enabled remote reporting where NFC tap-read is secondary; verify analog signal chain design effort. |
Compared with ST25DV64K and MAX32665, NHS3152UK/A1Z uniquely integrates NFC, Arm M0+, analog sensing, and ultra-low-power operation in one WLCSP die - eliminating external components required for foil-based pill monitoring and reducing total system footprint by >40%.

FAQ
What power sources does the NHS3152UK/A1Z support?
The NHS3152UK/A1Z supports dual power sources: external battery (1.72–3.6 V via VDDBAT) and passive NFC-field harvesting (via LA/LB terminals). An internal automatic source selector prioritizes VDDBAT when both are present. In battery-off mode, current draw is <50 nA - enabling multi-year shelf life before first activation. The NHS3152UK/A1Z enters active mode upon NFC field detection or RESETN assertion.
How does the NHS3152UK/A1Z interface with resistive foil networks for pill counting?
The NHS3152UK/A1Z uses its six AN0_x analog I/O pins (AN0_0 to AN0_5) connected to segmented foil traces. Through its on-chip analog switch matrix and shared ADC/CDC, it performs time-division multiplexed resistance measurements to detect breaks or continuity changes indicating pill removal. Firmware interprets voltage shifts to increment dose counters stored in EEPROM - all without external analog components. This capability is intrinsic to the NHS3152UK/A1Z architecture.
Is the NHS3152UK/A1Z NFC Forum certified?
Yes, the NHS3152UK/A1Z is NFC Forum Type 2 certified with certification ID 58524 (as of September 25, 2017). It complies fully with ISO/IEC 14443 Type A standards and supports standard NFC read/write operations - enabling interoperability with smartphones, point-of-care readers, and pharmacy systems without proprietary drivers. This certification applies directly to the NHS3152UK/A1Z in WLCSP25 packaging.
What is the temperature accuracy specification of the NHS3152UK/A1Z sensor?
The NHS3152UK/A1Z integrated temperature sensor achieves ±0.3 °C absolute accuracy between 0 °C and +45 °C - the clinically critical range for medication storage. Accuracy degrades to ±0.5 °C outside that band (−40 °C to 0 °C and +45 °C to +85 °C). Calibration is factory-trimmed; no user compensation is required. This performance is specified and guaranteed for the NHS3152UK/A1Z across its operating voltage and temperature range.
Can the NHS3152UK/A1Z be programmed in-system after assembly?
Yes, the NHS3152UK/A1Z supports in-system programming via Arm Serial Wire Debug (SWD) using the SWCLK and SWDIO pins (B5 and C5 in WLCSP25). It also allows firmware updates over NFC using the built-in bootloader. Both methods preserve EEPROM log data and support secure signature verification. Development toolchains including MCUXpresso IDE fully support the NHS3152UK/A1Z - no special hardware programmers are required beyond standard SWD probes.
