2.1 Features

The Sensor Controller has access to both analog and digital peripherals which include:

  • 12-bit ADC capable of sampling analog capable I/Os or internal chip voltages.
  • Two comparators: one high speed continuous time comparator (CompA) and one low-power clocked comparator updated at 32kHz (CompB).
  • 8-bit reference DAC capable of supporting the comparators with reference voltages.
  • SPI master interface.
  • Bit-banged serial interfaces including I2C master, UART and more.
  • Time to digital converter capable of measuring the time between configurable start and stop triggers.
  • Programmable current source capable of giving out currents between 0 and 20µA.
  • Two simple 16-bit timers.
  • Timer with PWM and four capture/compare channels allowing event setting and clearing without waking up the Sensor Controller.
  • 16-bit asynchronous multipurpose timer with 4 capture or compare channels.
  • Ultra low power 16-bit pulse counter capable of count rising edges on any digital input pins or comparator output.
  • Access to all GPIO pins.
