Introduce the waterproof and noise immunity of ML56 touch key. Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you the waterproof and noise immunity of ML56 touch key. First introduce the waterproof and noise immunity of ML56 touch key. Good waterproof function, support finger touch with 2 mm depth water droplet. IEC 61000-4-6 conducted noise immunity (CNI) with 10 Vrms noise voltage. Next, we will explain the related parameter settings of the ML56 touch key, and first explain the touch sensitivity. #Pulse Width (Touch key sensing pulse width time control) Touch key sensitivity can be adjusted by setting Pulse Width properly, shorter Pulse Width setting comes with poor sensitivity and less power-consumption, vice versa. Then explain the stability of touch performance, Part 1. #Times (Touch key sensing times control) Touch key raw data stability can be adjusted by setting Times properly, shorter Times setting comes with poor raw data stability and less power-consumption, vice versa. Stability of touch performance, Part 2. #IIR (IIR filter) IIR filter can control the ratio of current raw data and previous one. User can enable IIR Filter to be against noise. It will increase the touch response time when enables IIR Filter. Stability of touch performance, Part 3. #Debounce (Touch key debounce) Touch key stability can be adjusted by setting Debounce properly, the debounce times for touch key entry (on) and release (off) detection, shorter Debounce setting comes with faster touch response time, vice versa. Stability of touch performance, Part 4. #Trace Baseline (Baseline is generated by “Calibration”) Touch key auto environment compensation is an algorithm that baseline tracking each touch key automatically at power-up and keeps compensating environment variation affects touch key performance during runtime. Based on the above parameter description, the following introduces the waterproof and noise immunity parameter settings. The first is waterproof parameter setting. Good waterproof function, support finger touch with 2 mm depth water droplet. Touch key system parameters are shown in the table Pulse Width = 500 ns Times = 128 Next is the noise immunity parameter setting IEC 61000-4-6 conducted noise immunity (CNI) with 10 Vrms noise voltage. Touch key system parameters are shown in the table. Pulse Width = 2 us Times = 128 IIR New = 6, Old = 2 Debounce Entry = 1, Release = 1 Then we use the ML56 NuMaker Board to show you the waterproof function of the touch key. Dip the finger in water first, and then touch the touch key. Repeat the above actions, we can see that the touch key still works normally and is not affected. Finally, we use the ML56 NuMaker Board to show you the noise immunity ability of the touch key. Turn on the walkie-talkie first, and then interfere with the touch key at close range, we can see that the touch key still operate normally and is not affected.

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.
