Description
16/69
register to generate an alarm. A 20-bit prescaler is used for the time base clock and is by
default configured to generate a time base of 1 second from a clock at 32.768 kHz.
Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 40 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used as a watchdog to
reset the device when a problem occurs, or as a free running timer for application timeout
management. It is hardware or software configurable through the option bytes. The counter
can be frozen in debug mode.
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from the
main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.
SysTick timer
This timer is dedicated for OS, but could also be used as a standard down counter. It

General-purpose timers (TIMx)
There are 3 synchronizable general-purpose timers embedded in the STM32F102xx
medium-density USB access line devices. These timers are based on a 16-bit auto-reload
up/down counter, a 16-bit prescaler and feature 4 independent channels each for input
capture, output compare, PWM or one-pulse mode output. This gives up to 12 input
captures / output compares / PWMs on the LQFP48 and LQFP64 packages.
The general-purpose timers can work together via the Timer Link feature for synchronization
or event chaining. Their counter can be frozen in debug mode.
Any of the general-purpose timers can be used to generate PWM outputs. They all have
independent DMA request generation.
These timers are capable of handling quadrature (incremental) encoder signals and the
digital outputs from 1 to 3 hall-effect sensors.
I
Two I²C bus interfaces can operate in multi-master and slave modes. They can support
standard and fast modes. They support dual slave addressing (7-bit only) and both 7/10-bit
addressing in master mode. A hardware CRC generation/verification is embedded.
They can be served by DMA and they support SM Bus 2.0/PM Bus.
