NHS3152DBUL

NHS3152 Therapy adherence resistive monitor Rev. 5.02 27 May 2021 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, the NFC Forum has certified this device (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 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. msc896 NXP Semiconductors NHS3152 Therapy adherence resistive 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 input output (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 Analog-to-Digital Converter (ADC) Digital-to-Analog Converter (DAC) Current-to-Digital Converter (CDC) 6 analog I/O pins 2.5 Flexible analog on-chip switch Each of the six I/O pins can be dynamically connected to the on-chip converters.
