mXT2113TD-ABMK 1.0

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

Keys

Touch Sensor Technology

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

based sensors

•On-cell/touch-on display support includingTFT, 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 timedepending 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 VPPbetween 1 Hz and 1 kHz sinusoidal

waveform (no touches)

-Up to 20 VPP between 1kHz and 1MHz

sinusoidal waveform
