Note4: Ripple should be less than 300mVp-p.
Note5: Due to semiconductor technology principles and characteristics, the built-in RC oscillator’s frequency accuracy may drift (±1.5%) in high/low temperature environments. CI1316XP features built-in baud rate adaptation circuitry to ensure normal communication with the MCU in various temperature conditions. If your application requires highly accurate clocking, please use our chips with external crystal oscillators and corresponding application solutions.
