Note4: Ripple must be less than 100mVp-p.
Note5: Due to semiconductor technology principles and characteristics, the built-in RC oscillator’s frequency accuracy may experience temperature drift (±1.5%) in high/low temperature environments. The CI13082V features built-in baud rate adaptation circuitry to maintain normal communication with the MCU across temperature variations.
