Frequently asked questions
What supply voltage and oscillator configuration does the LM3S6G11-IQC80-A2 require?
The part operates from 3V to 3.6V — a tight regulated 3.3 V rail is required. The internal oscillator handles basic timing and UART baud generation without an external crystal, but LINbus and other protocol-sensitive serial links with tight baud-rate accuracy may need an external crystal to meet specification.
