View All Product from NXP USA Inc. 32.768 kHz quartz oscillator, amplitude regulated with excellent frequency stability andhigh immunity to leakage currents Two integrated quartz crystal oscillator capacitors Very low current consumption: typically 130 nA Two-wire serial interface (I2C-bus) Integrated 24-bit counter with auto increment every 32 seconds Interrupt output for processor wake-up Stop function for accurate time setting and current saving during shelf life User test modes for accelerated application testing and development
The PCA8802 is a CMOS integrated circuit for battery operation, typically supplied bybutton cells or flexible polymer batteries. Incorporated is a 32.768 kHz quartz crystaloscillator circuit including the two load capacitors. The circuit is optimized for a quartz with6 pF load capacitance specification. Higher values can also be used with the addition ofexternal load capacitors.The main function of the oscillator is to generate a 1⁄32 Hz clock signal which is used toincrement a 24 bit binary counter. The counter can be read over the serial interface andcan also be set to any desired value. Control over the divider chain also allows foraccurate starting of the counter. Incrementing of the counter value during read isprevented by freezing of the counter during access.An interrupt signal is also available and is triggered coincident with the counter updating.This signal can be used as a wake-up for a microcontroller.
