Overview
Features
Features
System
- Cortex-M0+ processor running at frequencies of up to 8 MHz
- Cortex-M0+ built-in Nested Vectored Interrupt Controller (NVIC)
- Arm serial wire debug
- System tick timer
- IC reset input
Memory
- 32 kB on-chip flash programming memory
- 4 kB on-chip EEPROM of which 256 bytes can be write protected
- 8 kB SRAM
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/sinks (20 mA) on four GPIO pins
- High-current drivers/sinks (20 mA) on two I2C-bus pins
- Programmable WatchDog timer (WDT)
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
Communication Interfaces
- NFC/RFID ISO 14443 type A interface
- I2C-bus interface supporting full I2C-bus specification and Fast-mode with a data rate of 400 kbit/s, with multiple address recognition and monitor mode
Clock Generation
- 8 MHz internal RC oscillator, trimmed to 2%, accuracy, which is used as the system clock
- Timer oscillator operating at 32 kHz linked to the RTC timer unit
Power Control
- Support for 1.72 V – 3.6 V external voltages
- The NHS3100 can also be powered from the NFC field
- Activation via NFC possible
- Integrated Power Management Unit (PMU) for versatile control of power consumption
- Four reduced power modes for Cortex-M0+: Sleep, Deep-sleep and Deep power-down and Battery-off
- Power gating for each analog peripheral for ultra-low power operation
- < 50 nA IC current consumption in Battery-off mode at 3.0 V
- Power-On Reset (POR)
