STMicroelectronics 

Functional overview

STM32F302xB STM32F302xC

The reference voltage can be one of the following:

• External I/O

• DAC output pin

• Internal reference voltage or submultiple (1/4, 1/2, 3/4). Refer to Table 28: Embedded

internal reference voltage on page 61 for the value and precision of the internal

reference voltage.

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

timers and can be also combined per pair into a window comparator

Timers and watchdogs

The STM32F302xB/STM32F302xC includes one advanced control timer, up to six general-

purpose timers, one basic timer, two watchdog timers and a SysTick timer. The table below

compares the features of the advanced control, general purpose and basic timers.
