Pin Configuration

I cannot extract a complete pinout table for the APM32F103C8T6 from the provided source material.

Issue

The datasheet section provided contains only a legend/abbreviations table (Table 2) that explains pin type symbols and naming conventions. It does NOT contain:

  • A pin assignment table with pin numbers and names
  • A pin diagram or package drawing showing pin positions
  • Any actual pinout information for the APM32F103C8T6 variant

What is needed

To extract the pinout for APM32F103C8T6 (LQFP-48 package), I would require:

  1. Pin assignment table from the datasheet (typically labeled "Pin Configuration" or "Pin Definitions")
  2. Pin diagram image showing the physical layout with pin numbers 1–48
  3. Or both combined

Recommendation

Please provide:

  • The pin configuration/assignment table section from the APM32F103 datasheet
  • A pin diagram image for the LQFP-48 package variant

Once either of these is supplied, I can extract a clean, accurate pinout table for the APM32F103C8T6.

Absolute Maximum Ratings

If the load on the device exceeds the absolute maximum rating, it may cause permanent

damage to the device. Here, only the maximum load that can be borne is given, and there is no guarantee that the device functions normally under this condition.
