Philips PCA167x Series Integrated Circuits Datasheet
This document is a product specification datasheet for the PCA167x series of integrated circuits manufactured by Philips Semiconductors. These devices are designed as 32 kHz watch circuits suitable for battery-operated, quartz-crystal-controlled wrist-watches using bipolar stepping motors.
The datasheet provides comprehensive technical details including features such as a 32 kHz amplitude-regulated oscillator with high immunity to leakage currents and very low current consumption (typically 150 nA). It includes ordering information for various types (PCA1672U through PCA1677U), pin configurations, functional descriptions of motor pulses and test modes, electrical specifications, limiting values, handling precautions, chip dimensions, package outlines, and typical application circuit diagrams.
