The Analog-to-Digital Converter (ADC) is based on a Successive Approximation Register (SAR)
10-bit ADC. It also integrates an 8-to-1 analog multiplexer, making possible the analog-to-digital
conversions of 8 analog lines. The conversions extend from 0V to ADVREF.
The ADC supports an 8-bit or 10-bit resolution mode, and conversion results are reported in a
common register for all channels, as well as in a channel-dedicated register. Software trigger,
external trigger on rising edge of the TRIGGER pin, or internal triggers from timer counter out-
put(s) are configurable.
The ADC also integrates a sleep mode and a conversion sequencer and connects with a Periph-
eral DMA Controller channel. These features reduce both power consumption and processor
intervention.
Finally, the user can configure ADC timings, such as startup time and sample & hold time.
Integrated multiplexer offering up to eight independent analog inputs
Individual enable and disable of each channel
Hardware or software trigger
Peripheral DMA Controller support
Possibility of ADC timings configuration
Sleep mode and conversion sequencer
– External trigger pin
– Timer counter outputs (corresponding TIOA trigger)
– Automatic wakeup on trigger and back to sleep mode after conversions of all enabled
channels
