Description

2.3.28

2.3.29

2.3.30

This dual digital Interface supports the following features:

● two DAC converters: one for each output channel

● 8-bit or 12-bit monotonic output

● 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 STM32F103xC, STM32F103xD and

STM32F103xE performance 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 < VDDA < 3.6 V. The temperature sensor is internally

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.
