This data sheet provides information on the PCA167x series 32 kHz watch circuits, including features, characteristics, and usage instructions.
The Philips PCA167x series consists of CMOS integrated circuits specifically suited for battery-operated, quartz-crystal-controlled wrist-watches with a bipolar stepping motor. These devices utilize either a silver-oxide or a 3 V lithium battery and feature a 32 kHz oscillator with excellent frequency stability.
| Oscillator Frequency | 32 kHz |
|---|---|
| Supply Voltage (Typical) | 1.5 V |
| Supply Current (Typical) | 150 nA |
| Operating Temperature Range | -10 to +60 C |
The devices use either a silver-oxide or a 3 V lithium battery.
Connecting the RESET to Vpp stops motor pulses and produces a 32 Hz signal at the TEST pin.
