Functional overview

Ultra-fast comparators (COMP)

The STM32F301x6/8 devices embed up to three ultra-fast rail-to-rail comparators which

offer the features below:

 Programmable internal or external reference voltage

 Selectable output polarity.

The reference voltage can be one of the following:

 External I/O

 DAC output

 Internal reference voltage or submultiple (1/4, 1/2, 3/4). Refer to Table 27: Embedded

internal reference voltage for the value and precision of the internal reference voltage.

All comparators can wake up from STOP mode, and also generate interrupts and breaks for

the timers.

Timers and watchdogs

The STM32F301x6/8 includes advanced control timer, up to general-purpose timers, basic

timer, two watchdog timers and a SysTick timer. The table below compares the features of

the advanced control, general purpose and basic timers.

1. TIM1/15/16/17 can be clocked from the PLL running at 144 MHz when the system clock source is the PLL and AHB or

APB2 subsystem clocks are not divided by more than 2 cumulatively.
