PAP1100QN: Low Power 10 Touch Controller
Description
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 mutual-
capacitance measurement technique, where it
senses capacitance changes on the touch
panel, and detects multiple touch points
simultaneously.
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,
reducing system cost. Its high-density
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
include:
Run mode
[150 Hz report rate, 1 TP]
Run mode
[150 Hz report rate, 5 TPs]
Shutdown
25 mW
30 mW
145 μW
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.
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.
