19 / 103 page  DocID023331 Rev 2 19/103 STM8L052C6 Functional overview 48 3.9 Analog-to-digital converter 12-bit analog-to-digital converter (ADC1) with 25 channels (including 1 fast channel) and internal reference voltage Conversion time down to 1 µs with fSYSCLK= 16 MHz Programmable resolution Programmable sampling time Single and continuous mode of conversion Scan capability: automatic conversion performed on a selected group of analog inputs Analog watchdog Triggered by timer Note: ADC1 can be served by DMA1. 3.10 System configuration controller and routing interface The system configuration controller provides the capability to remap some alternate functions on different I/O ports. TIM4 and ADC1 DMA channels can also be remapped. The highly flexible routing interface allows application software to control the routing of different I/Os to the TIM1 timer input captures. It also controls the routing of internal analog signals to ADC1 and the internal reference voltage VREFINT. 3.11 Timers The medium-density value line STM8L052C6 contains one advanced control timer (TIM1), two 16-bit general purpose timers (TIM2 and TIM3) and one 8-bit basic timer (TIM4). All the timers can be served by DMA1. Table 2 compares the features of the advanced control, general-purpose and basic timers. Table 2. Timer feature comparison Timer Counter resolution Counter type Prescaler factor DMA1 request generation Capture/compare channels Complementary outputs TIM1 16-bit up/down Any integer from 1 to 65536 Yes 3 + 1 3 TIM2 Any power of 2 from 1 to 128 2 None TIM3 TIM4 8-bit up Any power of 2 from 1 to 32768 0 |
