Analog to digital converter (ADC)
The STM8A products described in this datasheet contain a 10-bit successive approximation
ADC with up to 16 multiplexed input channels, depending on the package.
The ADC name differs between the datasheet and the STM8A/S reference manual (see
Table 8).

ADC features
• 10-bit resolution
• Single and continuous conversion modes
• Programmable prescaler: fMASTER divided by 2 to 18
• Conversion trigger on timer events, and external events
• Interrupt generation at end of conversion
• Selectable alignment of 10-bit data in 2 x 8 bit result registers
• Shadow registers for data consistency
• ADC input range: VSSA ≤VIN ≤VDDA
• Schmitt-trigger on analog inputs can be disabled to reduce power consumption

UART3
Universal synchronous/asynchronous receiver transmitter (USART)
The devices covered by this datasheet contain one USART interface. The USART can
operate in standard SCI mode (serial communication interface, asynchronous) or in SPI
emulation mode. It is equipped with a 16 bit fractional prescaler. It features LIN master
support.
