Overview<\/span>
\nThis module is an I2C bus interface-compliant real-time clock which includes a 32.768 kHz DTCXO. 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, Wakeup timer function,\uf020time update interrupt function,\uf020and 32.768 kHz output function. By the battery backup switchover function and the interface power supply input pin, RX8900 can support various power supply circuitries. The devices in this module are fabricated via a C-MOS process for low current consumption, which enables long-term battery back-up.<\/p>\n
