Philips PCA16xx Series 32 kHz Watch Circuits with EEPROM Datasheet
The Philips PCA16xx series consists of CMOS integrated circuits specially suited for battery-operated, quartz-crystal-controlled wrist-watches with bipolar stepping motors. The devices include a 32 kHz oscillator with excellent frequency stability and an internal EEPROM for electrically programmable time calibration. They require only a quartz crystal as an external component and offer very low current consumption, typically 170 nA.
