mXT1066T2 1.4
maXTouch 1066-node Touchscreen Controller
Product Brief
Description
The mXT1066T2 1.4 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. The mXT1066T2 1.4 allows for both
mutual and self capacitance measurements, with the self capacitance measurements being used to augment the mutual
capacitance measurements to produce reliable touch information.

Adaptive Sensing Touchscreen
Technology
• Up to 41 X (transmit) lines and 26 Y (receive) lines for
use by touchscreen and keys.
• A maximum of 1066 nodes can be allocated to the
touchscreen
• Touchscreen size of 12.4 inches (16:10 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 16 concurrent
touches tracked in real time
Touch Performance
• 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
• Glove Support
- Multiple-finger glove touches up to 1.5 mm
thickness (subject to stack-up design)
- Single-finger glove touch up to 5 mm thickness
(subject to stack-up design)
• Mutual capacitance and self capacitance
measurements supported for robust touch detection
• Noise suppression technology to combat ambient,
charger, and power-line noise
- Up to 240 V
PP
between 1 Hz and 1 kHz sinusoidal
waveform
- Up to 20 V
PP
between 1 kHz and 1 MHz
sinusoidal waveform
• Stylus Support
- Supports passive stylus with 1.5 mm contact
diameter, subject to configuration, stack-up, and
sensor design
• Scan Speed
- Up to 250 Hz reporting rate for one finger (subject
to configuration)
- Typical report rate for 16 touches
100
Hz
(subject to configuration)
- Initial touch latency <10 ms for first touch from idle
(subject to configuration)
- Configurable to allow for power and speed
optimization
Keys
• Up to 32 nodes can be allocated as mutual
capacitance sensor keys (subject to other
configurations)
• Adjacent Key Suppression (AKS) technology is
supported for false key touch prevention
Touch Sensor Technology
• Discrete/out-cell support including glass and PET film-
based sensors
• 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
• Works with PET or glass, including curved profiles
(configuration and stack-up to be approved by
Microchip or a Microchip-qualified touch sensor
module partner)
• Glass 0.4 mm to 4.5 mm (dependent on screen size,
touch size, configuration and stack-up)
• Plastic 0.2 mm to 2.2 mm (dependent on screen size,
touch size, configuration and stack-up)
On-chip Gestures
• Supports wake up/unlock gestures, including symbol
recognition
