Product specification
32 k Hz watch circuits with EEPROM
Features
- 32 k Hz oscillator, amplitude regulated with excellent frequency stability
- High immunity of the oscillator to leakage currents
- Time calibration electrically programmable and reprogrammable (via EEPROM)
- A quartz crystal is the only external ponent required
- Very low current consumption; typically 170 n A
- Detector for silver-oxide or lithium battery voltage levels
- Indication for battery end-of-life ORDERING INFORMATION TYPE NUMBER PCA1601U/10 PCA1602T PCA1603U/7 PCA1604U PCA1604U/10 PCA1605U/7 PCA1606U/10 PCA1607U PCA1608U PCA1611U PCA1621U/7 PCA1621U/10 PCA1622U PCA1623U/7 PCA1624U PCA1625U/7 PCA1626U PCA1627U/7 PCA1628U PCA1629U/7 Note PACKAGE(1) NAME
