5.8

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 10).

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

Communication interfaces

The following sections give a brief overview of the communication peripheral. Some

peripheral names differ between the datasheet and the STM8A/S reference manual (see

Table 11).

5.9.1

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.
