MTCH6303 Multi-Touch Projected Capacitive Touch Controller Product Brief Description Microchip’s MTCH6303 is an innovative turnkey projected capacitive touch controller that provides multi-touch coordinates as well as a readymade multi-finger surface gesture suite. MTCH6303 brings modern user interface (UI) elements – such as pinch and zoom, multi-finger scrolling, and swipes – to any embedded design, with minimal host requirements. The MTCH6303’s advanced signal processing provides noise-avoidance techniques and predictive tracking for ten fingers, typically at 100 Hz each for five touches. It also combines with Microchip’s MTCH652 High-voltage Line Driver to achieve a superior signal-to-noise ratio (SNR) for outstanding touch performance in noisy environments (refer to www.microchip.com/MTCH652). These capabilities are critical in demanding environments such as industrial controls, home and office automation with security control panels, thermostat, printers and lighting controls, and various consumer applications including exercise equipment and audio systems.

MTCH6303 PIN DESCRIPTIONS BOOSTDO RESET • MTCH6303 DO serial data output, connect to MTCH652 DIN Input. • Pulling the RESET pin low generates a device Reset. BOOSTPWM • MTCH652 OSCIN input signal for boost AVDD • Positive supply for analog modules. This pin must be connected at all times. BOOSTOE1 • Ground reference for analog modules. This pin must be connected at all times. • MTCH652 OE Outputs When OE is set to logic ‘0’, all MTCH652 output latches (OUTxx) are GND. When OE is set to logic ‘1’, all output latches that are set to drive ‘1’ will output the boost voltage level. SDA/SCL/IRQ BOOSTLE1 AVSS • • • • MTCH652 LE Outputs Latch Enable Input (LE) is the active-low latch input used for latching-in serial data. Serial data is ignored unless LE is logic ‘0’. After clocking serial data, the data is internally latched when LE changes from logic ‘0’ to logic ‘1’. I2C Data I2C Clock I2C Interrupt D+/D• USB D+ and D- COMM_SEL • Communication selection pin • VDD: I2C • GND: USB VUSB3V3 • USB internal transceiver supply If the USB module is not used, this pin must be connected to VDD OSC1/OSC2 • Clock signal input VCAP • A low-ESR capacitor is required on the VCAP pin, which is used to stabilize the internal voltage regulator output. The VCAP pin must not be connected to VDD and must have a CEFC capacitor, with at least a 6V rating, connected to ground. IN0-IN26 • RX sensor lines connect to the MTCH6303 IN pins. RX sensor lines must correspond to the longer axis of the touch sensor. TX sensor lines are connected to the required MTCH652.
