一.產品描述 提供6個觸摸感應按鍵,一對一直接輸出,輸出為開漏(opendrain)型態,適合作AD鍵。對於防水和抗干擾方面有很優異的表現! 二。產品特色 1.工作電壓範圍:3.1V – 5.5V 2.工作電流: 3mA@5V 3.6 個觸摸感應按鍵 4.提供一對一的直接輸出,未按鍵為開漏(open drain)型態輸出,按鍵時為低電平。 5.可以經由調整 CAP 腳的外接電容,調整靈敏度,電容越大靈敏度越高 6.具有防水及水漫成片水珠覆蓋在觸摸按鍵面板,按鍵仍可有效判別 7.內建 LDO 增加電源的抗干擾能力 三。 產品應用 各種大小家電,娛樂產品 四.功能描述 1.VK3606OM 於手指按壓觸摸盤,在 60ms 內輸出對應按鍵的狀態。 2.單鍵優先判斷輸出方式處理, 如果 K1 已經承認了, 需要等K1 放開後, 其他按鍵才能再被承認,同時間只有一個按鍵狀態會被輸出。 3.具有防呆措施, 若是按鍵有效輸出連續超過 10 秒, 就會做復位。 4.環境調適功能,可隨環境的溫濕度變化調整參考值,確保按鍵判斷工作正常。 5.可分辨水與手指的差異,對水漫與水珠覆蓋按鍵觸摸盤,仍可正確判斷按鍵動作。但水不可於按鍵觸摸盤上形成“水柱”,若如此則如同手按鍵一般,會有按鍵承認輸出。 6.內建 LDO 及抗電源雜訊的處理程序,對電源漣波的干擾有很好的耐受能力。 7.K0~K5 中不使用的按鍵請接地,避免太過靈敏而產生誤動。 8.D0~D5 中不使用的輸出請接地,避免浮接會有漏電流的情 況。

The concept of smart cities emerged few years ago as a new vision for urban development that aims to integrate multiple information and communication technology (ICT) solutions in a secure fashion to manage a city’s assets. Modern ICT infrastructure and e-services should fuel sustainable growth and quality of life, enabled by a wise and participative management of natural resources to be ensured by citizens and government. The need to build smart cities became a requirement that relies on urban development that should take charge of the new infrastructures for smart cities (broadband infrastructures, wireless sensor networks, Internet-based networked applications, open data and open platforms) and provide various smart services and enablers in various domains including healthcare, energy, education, environmental management, transportation, mobility and public safety.

The field of digital communication has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communi- cation networks (e.g., digital subscriber loop, cable, fiber optics), wireless communication (e.g., cell phones and wireless local area networks), and stor- age media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the mathematical background necessary to understand communication theory.
