1. Overview
This module is an four signal lines interface -compliant real-time clock which includes a 32.768-kHz quartz
oscillator that has been adjusted for high precision. In addition to providing a function for generating six types
of interrupts, a dual alarm function, an oscillation stop detection function (used to determine presence of valid
internal data at power-on), and a power supply voltage monitoring function, this module includes a digital clock
precision adjustment function that can be used to set various levels of precision.
Since the internal oscillation circuit is driven at a constant voltage, 32.768-kHz clock output is stable and free
of voltage fluctuation effects.
This implementation of multiple functions in one SMT package is ideal for applications ranging from cellular
phones to PDAs and other small electronic devices.
