1 / 7 page ![]() CF5760 series SEIKO NPC CORPORATION —1 CMOS Analog Clock IC OVERVIEW The CF5760 series are analog clock ICs that derive their timing from a 32.768 kHz oscillator element. They feature a reset function (optional seconds control function) which can be used to maintain accurate time. Vari- ous alarm functions and motor outputs are available to match a wide range of clock specifications.
