5.1 Analog-to-Digital Converter (ADC)

STM8 and MSPM0 both offer ADC peripherals to convert analog signals to a digital equivalent. For STM8, STM8L001XX and STM8L101XX do not have ADC module. STM8S series and the rest of STM8L series offer 10-bit or 12-bit ADC, respectively. For MSPM0, both device series feature a 12-bit ADC. Table 5-1 and Table 5-2 compare the different features and modes of the ADCs.

(1) Only MSPM0C1105 and MSPM0C1106 in C series support external reference.
(2) ADC can be triggered in standby mode, which changes the operating mode.
Table 5-2 Conversion Modes
STM8 MSPM0 Comments
Single conversion mode Single channel single conversion ADC samples and converts a single channel once
Single scan mode Sequence of channels conversion ADC samples a sequence of channels and converts once.
Continuous and buffered continuous modes Repeat single channel conversion The one selected channel is repeatedly sampled and converted
Continuous scan mode Repeat sequence of channels conversion The group of channels are sampled and converted repeatedly

ADC Code Examples: information about ADC code examples can be found in the MSPM0 SDK examples guide.
