NHS3100 NTAG SmartSensor temperature monitor Rev. 8.03 27 May 2021 Product data sheet 1 General description The NXP Semiconductors NHS3100 is a member of the NTAG SmartSensor product family. The IC is optimized for temperature monitoring and logging. It has an embedded NFC 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 temperature monitoring. The NHS3100 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 NHS3100 contains multiple features, including multiple power-down modes and a selectable CPU frequency of 8 MHz and down for ultra-low power consumption. Users can program this NHS3100 with the industry-wide standard solutions for Arm Cortex-M0+ processors. As of September 22, 2017, the NFC forum has certified this device (certification ID: 58516). 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 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.NXP Semiconductors NHS3100 NTAG SmartSensor temperature monitor 2 Features and benefits 2.1 System Arm Cortex-M0+ processor running at frequencies of up to 8 MHz Arm Cortex-M0+ built-in nested vectored interrupt controller (NVIC) Arm serial wire debug (SWD) System tick timer IC reset input 2.2 Memory 32 kB on-chip flash programming memory 4 kB on-chip EEPROM of which 320 bytes are write-protected 8 kB SRAM 2.3 Digital peripherals Up to 12 general-purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors and repeater mode GPIO pins which can be used as edge and level sensitive interrupt sources High-current drivers (sink only 20 mA) on four GPIO pins 2 High-current drivers (sink only 20 mA) on two I C-bus pins Programmable watchdog timer (WDT) 2.4 Analog peripherals Temperature sensor with: 0.5 C absolute temperature accuracy between 40 C and 0 C 0.3 C absolute temperature accuracy between 0 C and +45 C 0.5 C absolute temperature accuracy between +45 C and +85 C 2.5 Communication interfaces NFC/RFID ISO 14443 type A interface NFC Forum type 2 compatible 2 2 I C-bus interface supporting full I C-bus specification and fast mode with a data rate of 400 kbit/s, with multiple-address recognition and monitor mode 2.6 Clock generation 8 MHz internal RC oscillator, trimmed to 2 %, accuracy, which is used for the system clock Timer oscillator operating at 32 kHz linked to an RTC timer unit 2.7 Power control Support for 1.72 V to 3.6 V external voltages The NHS3100 can also be powered from the NFC field.
