Features

AI Translation
  • Up to 14 X (transmit) lines and 24 Y (receive) lines for use by a touchscreen and/or key array
  • A maximum of 336 nodes can be allocated to the touch sensor
  • Touchscreen size of 7.11 inches (16:9 aspect ratio), assuming a sensor electrode pitch of 6.5 mm. Other sizes are possible with different electrode pitches and appropriate sensor material
  • Multiple touch support with up to 10 concurrent touches tracked in real time
  • Up to 16 nodes can be allocated as mutual capacitance sensor keys in addition to the touchscreen, defined as 1 key array. Adjacent Key Suppression (AKS) technology is supported for false key touch prevention
  • Discrete/out-cell support including glass and PET film-based sensors
  • On-cell/touch-on display support including TFT, LCD (ITPS, IPS) and OLED
  • Synchronization with display refresh timing capability
  • Support for standard (for example, Diamond) and proprietary sensor patterns
  • Works with PET or glass, including curved profiles
  • 10 mm glass (or 5 mm PMMA) with bare finger
  • 6 mm glass (or 3 mm PMMA) with multi-finger 5 mm glove (2.7 mm PMMA equivalent)
  • Moisture/Water Compensation - No false touch with condensation or water drop up to 22 mm diameter. One-finger tracking with condensation or water drop up to 22 mm diameter
  • Mutual capacitance and self capacitance measurements supported for robust touch detection
  • P2P mutual capacitance measurements supported for extra sensitive multi-touch sensing
  • Noise suppression technology to combat ambient and power-line noise - Up to 240 VPP between 1 Hz and 1 kHz sinusoidal waveform (no touches) - IEC 61000-4-6, 7 Vrms, Class A (normal touch operation) conducted noise immunity
  • Stylus Support - Supports passive stylus with 1.5 mm contact diameter
  • Scan Speed - Typical report rate for 10 touches 290 Hz. Initial touch latency < 18 ms for first touch from idle. Configurable to allow for power and speed optimization
  • Touch panel failure detection - Automatic touch sensor diagnostics during run time to support the implementation of safety critical features - Diagnostics reported using dedicated output pin or by standard Object Protocol messages - Configurable test limits
  • Lens bending algorithms to remove display noise
  • Touch suppression algorithms to remove unintentional large touches, such as palm
  • Palm Recovery Algorithm for quick restoration to normal state
  • 60-byte CRC-checksummed data area for use as a run-time Product Data Store Area
  • Up to 64 bytes of user’s custom data (not CRC checksummed)
  • Encrypted configuration parameters and touch coordinate reports (OBP messages) using customer's own security key
  • Programmable timeout for automatic transition from Active to Idle state
  • Pipelined analog sensing detection and digital processing to optimize system power efficiency
  • I2C client interface for main communication with the device, with support for Standard mode (up to 100 kHz), Fast mode (up to 400 kHz), Fast-mode Plus (up to 1 MHz)
  • Interrupt to indicate when a message is available
  • Additional SPI Debug Interface to read the raw data for tuning and debugging purposes
  • Digital (Vdd) 3.3V nominal
  • Digital I/O (VddIO) 3.3V nominal
  • Analog (AVdd) 3.3V nominal
  • High voltage internal X line drive (XVdd) 6.6V with internal voltage pump
  • 56-pin XQFN 6×6×0.4 mm, 0.35 mm pitch
  • Operating Temperature -40℃ to +85℃
