Additional Details

The RTL8671S-CG is typically packaged in a BGA (Ball Grid Array) package for ease of manufacturing and reliability. It operates on a standard power supply and requires external memory (SDRAM) for program storage and execution. The software development kit (SDK) provided by Realtek includes drivers, middleware, and application examples to simplify product development.
