STM32F105xx, STM32F107xx
Eight DAC trigger inputs are used in the STM32F105xx and STM32F107xx connectivity line
family. The DAC channels are triggered through the timer update outputs that are also
connected to different DMA channels.
Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 2 V < V
< 3.6 V. The temperature sensor is internally
DDA
connected to the ADC1_IN16 input channel which is used to convert the sensor output
voltage into a digital value.

Serial wire JTAG debug port (SWJ-DP)
The ARM SWJ-DP Interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a
specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.

Embedded Trace Macrocell™
®
The ARM Embedded Trace Macrocell provides a greater visibility of the instruction and
data flow inside the CPU core by streaming compressed data at a very high rate from the
STM32F10xxx through a small number of ETM pins to an external hardware trace port
analyzer (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or
any other high-speed channel. Real-time instruction and data flow activity can be recorded
and then formatted for display on the host computer running debugger software. TPA
hardware is commercially available from common development tool vendors. It operates
with third party debugger software tools.
