Description STM32F100xC, STM32F100xD, STM32F100xE
This dual digital Interface supports the following features:
• two DAC converters: one for each output channel
• up to 10-bit output
• left or right data alignment in 12-bit mode
• synchronized update capability
• noise-wave generation
• triangular-wave generation
• dual DAC channels’ independent or simultaneous conversions
• DMA capability for each channel
• external triggers for conversion
• input voltage reference V
REF+
Eight DAC trigger inputs are used in the STM32F100xx. The DAC channels are triggered through the timer update outputs that are also connected to different DMA channels.
The temperature sensor has to generate a voltage that varies linearly with temperature. The conversion range is between 2 V < V
DDA
< 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.
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.
