MTCH6102 MTCH6102 Low-Power Projected Capacitive Touch Controller Description: Touch Features: Microchips MTCH6102 is a turnkey projected Gesture Detection and Reporting capacitive touch controller that simplifies adding Self-Capacitance Signal Acquisition gestures to touch interface designs with Multiple Built-in Filtering Options industry-leading low-power performance. It utilizes up to 15 channels to support taps, swipes, and scrolling on Power Management: XY touch pads and touch screens. MTCH6102 allows Configurable Sleep/Idle Frame Rates designers to quickly and easily integrate projected Standby mode <500 nA (typical) capacitive touch into their cost-sensitive, low-power Active mode <12 uA possible application. MTCH6102 provides developers with a flexible touch-sensing solution to optimize common constraints of size, power and cost that are critical to Communication Interface: applications such as wearable devices, remote 2 I C (up to 400 kbps) controls, gaming devices and track pads. Both Polling and Interrupt Schemes Supported Sync Signal Allows for Host Frame Detection Applications: 2 Field Upgradeable over I C Wearable Devices such as Headphones, Watches, Fitness Wristbands Operating Conditions: Track Pads and Computer Peripherals 1.8V to 3.6V, -40C to +85C Input Devices with Configurable Button, Keypad or Scrolling Functions Package Types: Any Interface with Single-Finger Gestures to Swipe, Scroll, or Doubletap Controls 28-Pin SSOP Home Automation Control Panels 28-Pin UQFN Security Control Keypads Automotive Center Stack Controls Gaming Devices Remote Control Touch Pads Touch Sensor Support: Up to 15 Channels Sensor Sizes up to 120 mm (4.7) Individual Channel Tuning for Optimal Sensitivity Works with Printed Circuit Board (PCB) Sensors, Film, Glass and Flexible Printed Circuit (FPC) Sensors Cover Layer Support: Plastic: up to 3 mm Glass: up to 5 mm Touch Performance: >200 Reports per Second (configurable) 12-Bit Resolution Coordinate Reporting 2014 Microchip Technology Inc.
