Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you ML56 Capacitive Touch Key PCB Design. First introduce the Touch Sensor Channel Selection. Touch Sensor Channels. ML56 series supports up to 14 touch sensor channels. #Reference Sensor It is recommended to select one reference sensor at touch sensor channel TK7 or TK14. Maximize the distance between the reference sensor and other signals to minimize crosstalk. #Shield Electrodes Put the shield electrode around the touch sensor to get better signal quality and waterproof capability. Recommended to select shield channel at touch TK0, TK4 or clock out pins (P3.2 / P4.6 / P5.7). Next, we will explain the PCB Layout Rules. #Touch Key Shapes Recommended to have a 10 x 10 mm sensor area for good touch key sensitivity. Larger touch sensor electrode work better for thicker cover. #Reference Sensor Recommended to assign the reference key at touch channel TK7 or TK14. Maximize the distance to other signals to minimize crosstalk. Round shape electrode with 1 mm diameter size is enough for normal case. #Ground Plane It is recommended that the traces of the touch key have a good hatched ground plane surround. It is recommended to have hatched ground plane under the touch keys. Hatched ground plane with 6 mil trace and 50 mil grid. #Shield Electrode Put touch keys with shield electrode around which provides the same phase signal around touch keys. Hatched shield electrode with 6 mil trace and 50 mil grid. Shield electrode area needs to keep filled around the touch key in greater than 10 mm width. Finally, explain the Touch Key Cover Thickness. As the cover thickness increases, the touch key sensitivities will decrease. Larger touch key size work better for thicker cover. Recommended touch key diameter size with difference acrylic cover thickness as shown in the table. That's all for today's video, thank you everyone!

Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you ML56 Capacitive Touch Key Technology. First introduce the Capacitive Touch Key Fundamentals. The capacitance of the sensor without a finger touch is called as “parasitic capacitance”, CP. Parasitic capacitance results from the electric field between the sensor (including the sensor pad and traces) and other conductors in the system such as the ground planes, traces, any metal in the product’s chassis or enclosure, etc. The capacitance between the sensor pad and the finger is CF. The total capacitance CT of the sensor is the sum of CP and CF. Next, we will explain the ML56 Capacitive Touch Key Sensing Method. ML56 implements two switching capacitor banks for injecting charges to CP (or CT) and CR. CR is the parasitic capacitance of reference channel. After touch key calibration, CP and CR are balanced with CB and CCB (comparator output is “low”). Touch the sensing touch key which makes CT = CP + CF Now the negative input terminal voltage of the comparator is lower than positive side and comparator output is “high”. ML56 touch key controller will increase CCB to CCB’ to balance CT and CR again (comparator output is “low”). A finger touch can be detected by checking the difference of CCB and CCB’. By comparing the CCB’ shift level from CCB, the steady state to a predetermined threshold, the algorithm can determine whether the touch key is in ON (Touch) or OFF (No Touch) state.

介紹與說明 Nuvoton NuMicro ML56 電容式觸控按鍵基本原理和感應方法。 哈囉大家好! 我是新唐 FAE Tim，今天為大家介紹 ML56 電容式觸控按鍵技術。 首先介紹 #電容式觸控按鍵基本原理。 在沒有手指觸摸的傳感器的電容稱為 “寄生電容” CP 。 寄生電容是由傳感器 (包括傳感器，走線和過孔) 與系統中其他導體 (例如接地層，走線，產品機構或外殼中的任何金屬等) 之間的電場所產生的。 傳感器和手指之間的電容為 CF，傳感器的總電容 CT 是 CP 和 CF 之和。 接著要說明 ML56 #電容式觸控按鍵感應方法。 ML56 實現了兩個可變電容器組，用於向 CP (或 CT) 和 CR 注入電荷。 CR 是參考通道的寄生電容，在觸控按鍵校正之後，CP 和 CR 與 CB 和 CCB 保持平衡 (比較器輸出為 “低準位”) 。 手指觸摸在目前偵測的觸控按鍵，導致 CT = CP + CF，使比較器的負輸入端電壓低於正輸入端，並且比較器輸出為 “高準位”。 ML56 觸控按鍵控制器會將 CCB 增加到 CCB’，以使 CT 和 CR 再次達到平衡 (比較器輸出為 “低準位”)。透過檢查 CCB 和 CCB’ 之間的差異，可以做手指觸摸的偵測。 CCB 增加到 CCB’ 的數值與預定的觸控門檻值來做比較，演算法可以確定觸控按鍵處於 ON (觸摸) 狀態還是 OFF (無觸摸) 狀態。 以上是這次的教學影片, 謝謝大家！ 如果您有任何問題，歡迎聯絡我們。 - 更多產品資訊，請至新唐科技網站 https://bit.ly/3hVdcmC 購買管道：https://direct.nuvoton.com/tw/low-power-8051-series/ 聯絡我們： SalesSupport@nuvoton.com #Product #Learning #Basic #zh-Hant
