SX8651EVK Evaluation kit for SX8651 multitouch controller
4
The SX8651EVK is an evaluation tool for the SX8651
multitouch controller.
The SX8651 is a multitouch controller that enables a
completely different user interaction with 4-wire resistive
touchscreen. It enables the detection of 2 fingers on the
touchscreen and several gestures like the rotation and the
pinch/ stretch.
This ultra low power touchscreen controller has been
optimized for portable equipment where power and board-
space are at a premium.
It incorporates a highly accurate 12-bit ADC for data
conversion and operates from a single 1.65 to 3.7V supply
voltage.
The SX8651 features a built-in preprocessing algorithm for
data measurements, which greatly reduces the host
processing overhead and bus activity. This complete
touchscreen
solution
includes
four
user-selectable
operation modes which offer programmability on different
configurations such as conversion rate and settling time,
thus enable optimization in throughput and power
consumption for a wide range of touch sensing
applications.
The touch screen inputs have been specially designed to
provide robust on-chip ESD protection of up to ±15kV in
both HBM and Contact Discharge, and eliminates the need
for external protection devices.
The SX8651 is offered in two tiny packages: 3.0 mm x
3.0 mm DFN and a 1.5 mm x 2.0 mm wafer-level chip-scale
package (WLCSP).
