1. Overview
This module is an I
2C bus interface-compliant real-time clock which includes a 32.768-kHz crystal oscillator.
In addition to providing a calendar (year, month, date, day, hour, minute, second) function and a clock counter
function, this module provides an abundance of other functions including an alarm function, fixed-cycle timer
function, time update interrupt function, and 32.768-kHz output function.
The devices in this module are fabricated via a C-MOS process for low current consumption, which enables
long-term battery back-up.
All of these many functions are implemented in a thin, compact SON package, which makes it suitable for
various kinds of mobile telephones and other small electronic devices.
