Weekdays Month Years / INT Minutes Alarm CONTROL Hour Alarm LOGIC 2 SCL SDA Day Alarm I C-BUS The various interrupt function Timer function can be set up between 1/4096 second and 255 minutes. Alarm function can be set to day of week, day, hour, or minute. Weekday Alarm INTERFACE CLKOUT frequency ADDRESS Timer Control REGISTER Timer POR 0F Pin Function Terminal connection/External dimensions (Unit:mm) Functions Input Bi-directional CLKOUT Output Serial clock input. Data input and output. The CLKOUT pin is a clock output(open drain output)pin with control output.(Output frequency can be selected as 32.768kHz, 1024Hz, 32Hz, or 1Hz.) The CLKOE pin is an input pin used to control the output mode of the CLKOUT output pin. During the initial power-on(when power is applied from 0 V), if the CLKOE input pin is at high level(= H), the power-on reset function selects 32.768kHz as the frequency. Interrupts output by Alarm and Timer events.(Open drain output) Connected to a positive power supply. Connected to a ground. CLKOE /INT VDD GND Input Output   1. N.C. 2. SCL 3. SDA 4.

The environmental management system (EMS) operates under the ISO 14001 environmental management standard. All of our major manufacturing and non-manufacturing sites, in Japan and overseas, completed the acquisition of ISO 14001 certification. ISO 14000 is an international standard for environmental management that was established by the International Standards Organization in 1996 against the background of growing concern regarding global warming, destruction of the ozone layer, and global deforestation. WORKING FOR HIGH QUALITY In order provide high quality and reliable products and services than meet customer needs, Seiko Epson made early efforts towards obtaining ISO9000 series certification and has acquired ISO9001 for all business establishments in Japan and abroad. We have also acquired ISO/TS 16949 certification that is requested strongly by major automotive manufacturers as standard. ISO/TS16949 is the international standard that added the sector-specific supplemental requirements for automotive industry based on ISO9001. ►Explanation of the mark that are using it for the catalog ►Pb free. ►Complies with EU RoHS directive. *About the products without the Pb-free mark.
