mXT144UD-AMBSL 1.0

Description

The mXT144UD-AMxSL 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 sensor 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 mXT144UD-AMxSL 1.0

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.

Keys

Touch Sensor Technology

•On-cell/touch-on display support including OLED,TFT

and LCD (ITPS, IPS)

•Discrete/out-cell support including glass and PET film-

based sensors

•Synchronization with display refresh timing capability

•Support for slider touch sensor patterns designed

following Microchip guidelines(review of designs by

Microchip or a Microchip-qualified touch sensor

module partner is recommended)

Front Panel Material

Touch Performance

•Moisture/Water Compensation

-No false touch with condensationor water drop

up to 22mm diameter

-One-finger tracking with condensation or water

drop up to 22mm 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

•Burst Frequency

-Flexible and dynamic Tx burst frequency selection

to reduce EMC disturbance

-Configurable Tx waveform shaping to reduce

emissions

•Scan Speed

-Typical report rate for 5 touches 120Hz (subject

to configuration)

-Initial touch latency <6 ms for first touch from idle

(subject to configuration)

•AEC-Q100 Qualified

•CISPR25 compliant(for both mutual and self

capacitance measurements)

•Up to 12 X (transmit) lines and 12 Y (receive) linesfor

use by a slider and/or key array

•A maximum of 144 nodes can be allocated to the

touch sensor

•Slider length 936 mm, assuming a sensor electrode

pitch of 6.5mm. Other lengths 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 slider,

defined as 1 key array (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, including curved profiles

(configuration and stack-up to be approved by

Microchip or a Microchip-qualified touch sensor

module partner)

•10mm glass (or 5mm PMMA) with bare finger

(dependent on sensor size, touch size, configuration

and stack-up)

•6mm glass (or 3mm PMMA) with multi-nger 5mm

glove (2.7mm PMMA equivalent) (dependent on

sensor size, touch size, configuration and stack-up)
