Description
The mXT2113TD-ATMK/mXT2113TD-ABMK 1.0 uses a unique charge-transfer acquisition engine to implement Microchip’s
patented capacitive sensing method. Coupled with a state-of-the-art CPU, the entire touchscreen sensing solution can measure,
classify and track a number of individual finger touches with a high degree of accuracy in the shortest response time.
Automotive Applications
Microchip/Panasonic Knob Technology
• Detect and report the detent (click position) of specific
capacitive mechanical rotary encoders (knobs)
mounted on the touch panel
• Support for up to 4 Knob instances with different size
and number of detents (64 detents maximum)
• Position and size of each knob is individually
configurable. No specific touch pattern required
• Report relative detent position as well as the direction
of rotation
• Configurable suppression area around the knob to
suppress accidental touches from fingers holding the
knob
• Optional push/release function
• Design guidance, tools and other services available
from Microchip and Panasonic
maXTouch® Adaptive Sensing Technology
Keys
Touch Sensor Technology
• 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 (review of designs by
Microchip or a Microchip-qualified touch sensor
module partner is recommended)
Front Panel Material and Design
• Support for non-rectangular sensor designs (for
example, circular, rounded or with cutouts)
Touch Performance
• Moisture/Water Compensation
- No false touch with condensation
• P2P mutual capacitance measurements supported for
extra sensitive multi-touch sensing
• Noise suppression technology to combat ambient and
power-line noise
• Burst Frequency
- Flexible and dynamic Tx burst frequency selection
to reduce EMC disturbance
- Controlled Tx burst frequency drift over process
and temperature range
• AEC-Q100 Qualified
• CISPR 25 compliant
• Up to 33 X (transmit) lines and 64 Y (receive) lines for
use by a touchscreen and/or 2 key arrays
• A maximum of 2112 nodes can be allocated to the
touch sensor
• Touchscreen size of 16.9 inches (2:1 aspect ratio),
assuming a sensor electrode pitch of 6 mm. The
achievable touchscreen size depends on the knob
requirements
• Multiple touch support with up to 16 concurrent
touches tracked in real time depending on the number
of knobs implemented
• Up to 32 nodes can be allocated as mutual
capacitance sensor keys in addition to the
touchscreen, defined as 2 key arrays (subject to
availability of X and Y lines and other configurations)
• Adjacent Key Suppression (AKS) technology is
supported for false key touch prevention
• Works with PET or glass (dependent on sensor size,
touch size, configuration, stack-up, and dimension and
number of detents of the knob)
• Configuration and stack-up to be approved by
Microchip or a Microchip-qualified touch sensor
module partner
- Up to 240 VPP between 1 Hz and 1 kHz sinusoidal
waveform (no touches)
- Up to 20 VPP between 1 kHz and 1 MHz
sinusoidal waveform

• Scan Speed
- Typical report rate for 10 touches 120 Hz (subject to configuration)
- Initial touch latency <20 ms for first touch from idle (subject to configuration)
- Panasonic Knob rotation speed maximum 80 rpm
- Configurable 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
Enhanced Algorithms
• Dedicated drift calibration algorithm for the knob locations
• Lens bending algorithms to remove display noise
• Touch suppression algorithms to remove unintentional large touches
• Palm Recovery Algorithm for quick restoration to normal state
Data Store
• 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)
Power Saving
• Programmable timeout for automatic transition from Active to Idle state
• Pipelined analog sensing detection and digital processing to optimize system power efficiency
Application Interfaces
Power Supply
Package
