8.18 COMP

The comparator peripheral in the device compares the voltage levels on two inputs terminals and provides a digital output based on this comparison. It supports the following key features:

  • Programmable hysteresis
  • Programmable reference voltage:
    • External reference voltage (VREF IO)
    • Internal reference voltage (1.4V, 2.5V)
    • Integrated 8-bit reference DAC
  • Configurable operation modes:
    • High-speed mode
    • Low-power mode
  • Programmable output glitch filter delay
  • Supports 6 blanking sources from TIMx instances (see Table 8-8)
  • Device wakeup from all low power modes using comparator output
  • Output connected to advanced timer fault handling mechanism
  • Selection of comparator channel inputs from device pins or internal analog module (see Table 8-9, Table 8-10 and Table 8-11)
