Pin Function
Terminal CE CLK DI DO CLKOUT Directions Input Input Input Output Output Functions Chip enabled input. Serial clock input. Data input. Data 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. CLKOE Input 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 ) VDD GND

"QMEMS" EPSON TOYOCOM
In order to meet customer needs in a rapidly advancing digital, broadband and ubiquitous society, we are committed to offering products that are one step ahead of the market and a rank above the rest in quality. To achieve our goals, we follow a "3D (three device) strategy" designed to drive both horizontal and vertical growth. We will to grow our three device categories of "Timing Devices", "Sensing Devices" and "Optical Devices", and expand vertical growth through a combination of products from these categories. A Quartz MEMS is any high added value quartz device that exploits the characteristics of quartz crystal material but that is produced using MEMS (micro-electro-mechanical system) processing technology. Market needs are advancing faster than previously imagined toward smaller, more stable crystal products, but we will stay ahead of the curve by rolling out products that exceed market speed and quality requirements. We want to further accelerate the 3D strategy by QMEMS. Quartz devices have become crucial in the network environment where products are increasingly intended for broadband, ubiquitous applications and where various types of terminals can transfer information almost immediately via LAN and WAN on a global scale. Epson Toyocom Corporation addresses every single aspect within a network environment. The new corporation offers "Digital Convergence" solutions to problems arising with products for consumer use, such as, core network systems and automotive systems.
PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM CONFORMING TO INTERNATIONAL STANDARDS
At Epson Toyocom, all environmental initiatives operate under ISO 14000 is an international standard for environmental management the Plan-Do-Check-Action(PDCA) cycle designed to achieve that was established by the International Standards Organization in 1996 continuous improvements. The environmental management against the background of growing concern regarding global warming, system (EMS) operates under the ISO 14001 environmental destruction of the ozone layer and global deforestation management standard. All of our major manufacturing and non-manufacturing sites,in Japan and overseas, completed the acquisition of ISO 14001 certification. In the future, new group companies will be expected to acquire the certification around the third year of operations.
WORKING FOR HIGH QUALITY
In order provide high quality and reliable products and services than meet customer needs, Epson Toyocom 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.
QS-9000 is an enhanced standard for quality assurance systems formulated by leading U.S. automobile manufacturers based on the international ISO 9000 series. ISO/TS 16949 is a global standard based on QS-9000, a severe standard corresponding to the requirements from the automobile industry.
