24 VCMP - Voltage Comparator
24.1 Introduction
24.2 Features
2010-09-06 - d0001_Rev1.00
The Voltage Supply Comparator is used to monitor the supply voltage from software. An interrupt can
be generated when the supply falls below or rises above a programmable threshold.
Note
• Voltage supply monitoring
• Scalable V
• Internal 1.25 V bandgap reference
• Low power mode for internal V
• Selectable hysteresis
• Selectable response time
• Asynchronous interrupt generation on selectable edges
• Operational in EM0-EM3
• Comparator output direct on PRS
• Configurable output when inactive to avoid unwanted interrupts
0 1 2 3
• 0 or ±20 mV
• Rising edge
• Falling edge
• Rising and Falling edges

Note that VCMP comes in addition to the Power-on Reset and Brown-out Detector
peripherals, that both generate reset signals when the voltage supply is insufficient for
reliable operation. VCMP does not generate reset, only interrupt. Also note that the ADC is
capable of sampling the input voltage supply.

What?
The Voltage Supply Comparator (VCMP)
monitors the input voltage supply and
generates software interrupts on events using
as little as 100 nA.
Why?
The VCMP can be used for simple power
supply monitoring, e.g. for a battery level
indicator.
How?
The scaled power supply is compared to a
programmable reference voltage, and an
interrupt can be generated when the supply
is higher or lower than the reference. The
VCMP can also be duty-cycled by software to
further reduce the energy consumption.
