Product overview
It is clocked by the 128 kHZ LSI internal RC clock source, and thus stays active even in case
of a CPU clock failure
The IWDG time base spans from 60 Āµs to 1 s.
4.8
Auto wake-up counter
ā Used for auto wake-up from active halt mode
ā Clock source: internal 128 kHz internal low frequency RC oscillator or external clock
4.9
Beeper
The beeper function outputs a signal on the BEEP pin for sound generation. The signal is in
the range of 1, 2 or 4 kHz.

TIM1 - 16-bit advanced control timer
This is a high-end timer designed for a wide range of control applications. With its
complementary outputs, dead-time control and center-aligned PWM capability, the field of
applications is extended to motor control, lighting and half-bridge driver.
ā 16-bit up, down and up/down autoreload counter with 16-bit prescaler
ā 4 independent capture/compare channels (CAPCOM) configurable as input capture,
output compare, PWM generation (edge and center aligned mode) and single pulse
mode output
ā Synchronization module to control the timer with external signal
ā Break input to force the timer outputs into a defined state
ā 3 complementary outputs with adjustable dead time
ā Encoder mode
ā Interrupt sources: x input capture/output compare, 1 x overflow/update, 1 x break
4.11
TIM2- 16-bit general purpose timer
ā 16-bit autoreload (AR) up-counter
ā 15-bit prescaler adjustable to fixed power of 2 ratios 1ā¦32768
ā Timers with 3 or 2 individually configurable capture/compare channels
ā PWM mode
ā Interrupt sources: 2 or 3 x input capture/output compare, 1 x overflow/update
4.12
TIM4 - 8-bit basic timer
ā 8-bit autoreload, adjustable prescaler ratio to any power of 2 from 1 to 128
ā Clock source: CPU clock
ā Interrupt source: 1 x overflow/update
