SX8654/SX8655/SX8656
Haptics Enabled 4/5-Wire
Resistive Touchscreen Controller with Proximity Sensing
GENERAL DESCRIPTION
The SX8654, SX8655 and SX8656 belong to a family
of
high
performance
haptics
enabled
4/5-wire
resistive
touch
screen
controller
with
proximity
detection, optimized for hand held applications such
as mobile phones, portable music players, game
machines,
point-of-sales
terminal
and
other
consumer and industrial applications. They feature a
wide input supply range from 2.3V to 3.6V.
The
controller
computes
touch
screen
X-Y
coordinates and touch pressure with a precision, low
power 12-bit analog-digital converter.
On-chip data
averaging processing algorithms can be activated to
reduce host activity and suppress system noise. The
processing core features low power modes which
intelligently minimize current in operation as well as in
automatic shut-down.
A capacitive proximity detection circuit has been
integrated into the SX8654 and SX8656 to enable
host
controlled
power
management
for
battery
applications. Proximity detection above 5 cm is
possible using either the resistive touch screen as the
sensor or with a single conductive plate, with
communication to the host via the serial interface.
The SX8654 and SX8655 also integrate a haptics
motor driver for Linear Resonant Actuator (LRA) and
Eccentric Rotating Mass (ERM) micro motors with up
to 250mA drive current.
Haptics control can be
performed using either an external PWM signal or the
I2C serial interface, providing simple host interfacing
and minimizing its I/O requirement.
Integrated very high ESD protection, of up to ±15kV
on display inputs not only saves cost and board area,
but also increases application reliability.
The three devices have an ambient operating
temperature range of -40°C to +85°C, and are offere d
in both a 4mm x 4mm, 20-lead QFN package and
2.07mm x 2.07mm 19-lead CSP package for space-
conscious applications.
TYPICAL APPLICATIONS
Game Machines, Portable Music Players
Mobile Phones
DSC, DVR, Phones
POS/POI Terminals
Touch-Screen Monitors
