mtch102/5/8 ds40001793c-page 6 preliminary ? 2015-2016 microchip technology inc. 1.0 device overview the mtch102/5/8 provides an easy way to add proximity or touch detection to any application with human machine interface. these devices can integrate up to two, five and eight capacitive touch/proximity detection sensors which can work through plastic, wood or even metal front panels with microchip?s proprietary metal over capacitive technology. it also supports a wide range of conductive materials as sensors, like copper pad on pcb, silver ink, pedot or carbon printing on plastic film, indium tin oxide (ito) pad, wire/cable, etc. the mtch102/5/8 uses a sophisticated scan optimization algorithm to actively attenuate noise from the signal. the sensitivity adjustment and flexible power mode allow users to easily configure the device at run-time. an active-low output will communicate the state of the sensors to a host/master mcu or drive an indication led. figure 1-1: mtch102/ 5/8 block diagram 1.1 pin description mtix connect the sensor to this input. an additional resistor of at least 4.7 k ? is recommended for best noise immunity. sensors work best when the base capacitance is minimized. this will maximize the percentage change in capacitance when a finger is added to the circuit. the recommended sensor capacitance is 5pf to 50pf. mtox the mtox pin is an open-drain output which reports the touch/proximity state of the corresponding mtix input. a pull-up resistor is required on each output. the mtox will pull the line low when a touch/proximity event happens and release the line when the touch/ proximity is released. guard the guard function is multiplexed with one of the mtix pins. if the gc pin is floating, the guard pin will function as a standard mtix sensor. if the gc pin is grounded, the guard pin will output a signal in-phase with the other sensors being scanned. this has several advantages, such as providing a mutual capacitance coupling to the sensors to increase sensitivity, and providing a low-impedance trace near the sensor to absorb noise. the active guard layout should encircle the sensor and its traces so that it will shield the sensor. for more information about guarding and layout guidelines, see application notes ?mtouch ? sensing solution acquisition methods capacitive voltage divider? (an1478) and ?techniques for robust touch sensing design? (an1334).
? 2015-2016 microchip technology inc. preliminary ds40001793c-page 7 mtch102/5/8 gc the gc (guard control) is multiplexed with one of the mtox pins. by grounding the gc pin, the active guard signal will be enabled on the guard pin. mtsa the mtsa pin is an input that determines the sensitivity of touch/proximity sensors. applying v dd will give the lowest sensitivity while applying v ss will give the highest. mtpm the mtpm pin is an input that determines the power mode of mtch10x devices. by connecting v ss to the mtpm pin, the device will operate in low-power mode. see figure 5-1 for current consumption and response time specifications. when applying v dd on the mtch10x mtpm pin, the device will scan the sensors at the fastest possible sampling rate. host-controlled sampling rates are available using the smart scan scheduling feature described in section 4.0, power mode and timeout reset .

? 2015-2016 microchip technology inc. preliminary ds40001793c-page 9 mtch102/5/8 3.0 sensitivity adjustment the sensitivity of the sensor inputs determines how far it can respond to proximity or how much capacitance is required to activate a touch. the voltage on the mtch102/5/8 mtsa pin will determine the sensitivity. v dd voltage will give the lowest sensitivity, while v ss voltage will give the highest. the device will sample the voltage on the mtsa pin after every 32 nd scan, so it does not only support setting a fixed sensitivity by a resistor ladder, but it also allows adjusting the sensitivity dynamically while the device is running. a digital-to-analog converter (dac) controlled by the host or a hardware potentiometer can be used to adjust the sensitivity. refer to the typical circuit in figure 3-1 to figure 3-4 . figure 3-1: fixed sensitivity using resistor ladder figure 3-2: hardware sensitivity adjust using potentiometer figure 3-3: sensitivity controlled by host using dac figure 3-4: sensitivity controlled by host using pwm note: both r1 and r2 are recommended to be greater than 100k for lower power consumption. 10k r3 r1 v dd r2 mtsa 10k r2 r1 v dd mtsa 10k r2 mtsa host dac note: refer to application note ?using pwm to generate analog output?

mtch102/5/8 ds40001793c-page 10 preliminary ? 2015-2016 microchip technology inc. 4.0 power mode and timeout reset the mtch102/5/8 has three power mode options to meet the needs of various applications: normal mode, low-power mode and smart-scheduling mode. the state of the mtpm pin determines the power mode. 4.1 normal mode the device will run in normal mode if the mtpm pin is connected to v dd . in this mode, the mtch102/5/8 will scan continuously; so it will achieve the shortest response time among the three power modes, but also the power consumption is the highest. 4.2 low-power mode the device will run in low-power mode if the mtpm pin is connected to v ss . the device will go to sleep for 256 ms after each round of sensor scans; so it will achieve the lowest power consumption, but it will have the longest response time among the three power modes, as shown in figure 4-1 . figure 4-1: low-power mode 4.3 smart-scheduling mode the mtch102/5/8 also implements a smart-scheduling mode that allows a host to set the exact sampling rate by pulsing the mtpm pin, as shown in figure 4-2 . the minimum recognizable pulse width is 25 ns. if the mtpm pin is toggled during a scan cycle, the device will skip the next sleep and immediately start a new set of scans. figure 4-2: smart-scheduling mode 4.4 timeout reset the device keeps track of the activated state duration for each mtix input channel. the sensor state will be reset once the activated state duration exceeds the timeout duration, and the associated mtox pin will release the line. for the normal and low-power modes, the timeout duration is 10 seconds. for the smart-scheduling mode, the timeout duration is 400 multiplied by the scan interval. mtix burst scan sleep:256 ms mtix burst scan sleep mtpm scan interval
