SX8651EVK Evaluation kit for SX8651 multitouch controller
4
GENERAL DESCRIPTION
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
operation modes which offer programmability on different
configurations such as conversion rate and settling time,
thus enable optimization in throughput and power

includes four user-selectable

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).
