Watchdog timers
The watchdog system is based on two independent timers providing maximum security to
the applications.
3.14.1
Window watchdog timer
The window watchdog (WWDG) is used to detect the occurrence of a software fault, usually
generated by external interferences or by unexpected logical conditions, which cause the
application program to abandon its normal sequence.
3.14.2
Independent watchdog timer
The independent watchdog peripheral (IWDG) can be used to resolve processor
malfunctions due to hardware or software failures.
It is clocked by the internal LSI RC clock source, and thus stays active even in case of a
CPU clock failure.
3.15
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.
3.16
Communication interfaces
3.16.1
SPI
The serial peripheral interface (SPI1) provides half/ full duplex synchronous serial
communication with external devices.
Maximum speed: 8 Mbit/s (fSYSCLK/2) both for master and slave
Full duplex synchronous transfers
Simplex synchronous transfers on 2 lines with a possible bidirectional data line
Master or slave operation - selectable by hardware or software
Hardware CRC calculation
Slave/master selection input pin
Note:
SPI1 can be served by the DMA1 Controller.
3.16.2
IC
The I2C bus interface (I2C1) provides multi-master capability, and controls all IC bus-
specific sequencing, protocol, arbitration and timing.
Master, slave and multi-master capability
Standard mode up to 100 kHz and fast speed modes up to 400 kHz.
7-bit and 10-bit addressing modes.
SMBus 2.0 and PMBus support
Hardware CRC calculation
