Peripheral ADC[edit | edit source]

The ADC module available on AURA is based on i.MX93 SoC. The SOC has one instance of the ADC module: it is an 8-channel 12-bit 1MS/s ADC with 4 channels connected to pins in the package. It has its own dedicated pads and is not muxed with GPIO.

Description[edit | edit source]

The ADC port supports the following features:

  • Successive Approximation Register (SAR) method
  • 4-channel, 12-bit resolution
  • Multiple modes of starting conversion (Normal, Injected)
  • Software-initiated conversions in Normal and Injected modes, or external hardware trigger
  • Programmable DMA enables for each channel
  • Programmable presampling for channels
  • Programmable clock prescaler
  • Software-initiated calibration

Pin mapping[edit | edit source]

The Pin mapping is described in the Pinout table section
