The KC3215A series is a miniature 32.768kHz clock oscillator with a tuning fork blank. By adopting a tuning fork crystal, the KC3215A series realized ultra low current consumption up to 0.8µA at 3.3 Vol. Initial frequency tolerance is +5 to +/-23 ppm, and frequency stability over temperature is -120 ppm to +10ppm over -40 to +85°C.
