This module is an l2C 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.
