•

8-bit or 12-bit output mode

•

Left or right data alignment in 12-bit mode

•

Synchronized update capability

•

Noise-wave generation

•

Triangular-wave generation

•

Dual DAC channel independent or simultaneous conversions

•

DMA capability for each channel

•

External triggers for conversion

•

Input voltage reference (VREF+)

Eight DAC trigger inputs are used in the device. 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 1.7 V and 3.6 V. The temperature sensor is internally

connected to the ADC_IN18 input channel which is used to convert the sensor output

voltage into a digital value. Refer to the reference manual for additional information.

As the offset of the temperature sensor varies from chip to chip due to process variation, the

internal temperature sensor is mainly suitable for applications that detect temperature

changes instead of absolute temperatures. If an accurate temperature reading is needed,

then an external temperature sensor part should be used.

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.

Debug is performed using 2 pins only instead of 5 required by the JTAG (JTAG pins could

be re-use as GPIO with alternate function): the JTAG TMS and TCK pins are shared with

SWDIO and SWCLK, respectively, 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

STM32F413xG/H 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 any high-speed

channel available. Real-time instruction and data flow activity can be recorded and then

formatted for display on the host computer that runs the debugger software. TPA hardware

is commercially available from common development tool vendors.

The Embedded Trace Macrocell operates with third party debugger software tools.
