PAP1100QN: Low Power 10 Touch Controller
The PAP1100QN is a low-power, 10-touch
controller designed specifically to provide a
touch screen system with high report rate, touch
accuracy, and responsive on-screen navigation,
with very low latency. The IC uses a mutualcapacitance measurement technique, where it
senses capacitance changes on the touch
panel, and detects multiple touch points
The PAP1100QN touch controller is designed
specifically for applications in a high-noise
environment. It is robust against common-mode,
display, and RF noise; thereby eliminating the
need for a Ground shield on the touch panel,
drive/sense lines support touch screens up to 5”,
with 10 simultaneous touch points. A passive
stylus is also supported. Larger screens can
also be supported where fine-cell spacing is not
a priority.
The low-power design is ideal for extending
battery life. Programmable power modes

25 mW
The controller IC operates from a single 1.72 –
2.0 V or 2.5 – 3.6 V supply voltage, with I/O
voltage from 1.6 to 3.6 V. The part is housed in
a 6 x 6 x 0.55 mm 48-pin TQFN package.
Multi-touch navigation (up to 10 points)
Support for up to 5” screen (larger
depending on application)
Adjustable touch thresholds for up to 1.5
mm PMMA or PC curved lens
Cover lens: up to 2 mm glass or 1.5 mm
Gesture support
Buttons and sliders support
Opens/shorts test support
Internal flash for saving user settings
1200 DPI resolution at full screen
Greater than 200 Hz configurable report rate
Fast response time: < 10 ms
30 mW
SPI/I2C host interface
145 μW
Operating temperature: -20 to +70 C
Haptics output, support for up to 10
waveforms, and a variety of triggers
Lead-free RoHS compliant
Additional programmable Idle/Rest modes are
also available.
There are 30 kbytes of Flash memory for Pixart
supplied based-line operational code storage. In
addition, there are 2 kbytes of Flash memory for
application-specific data storage, such as saved
register settings, customized configurations of
drive/sense mapping, buttons, sliders and
haptics. There is no overlap between the 30
kbytes and 2 kbytes spaces.
