SX8651EVK ADVANCED COMMUNICATIONS & SENSING USER GUIDE User Guide SX8651EVK Evaluation kit for SX8651 multitouch controller 4 consumption for a wide range of touch sensing GENERAL DESCRIPTION applications. The SX8651EVK is an evaluation tool for the SX8651 The touch screen inputs have been specially designed to multitouch controller. provide robust on-chip ESD protection of up to 15kV in The SX8651 is a multitouch controller that enables a both HBM and Contact Discharge, and eliminates the need completely different user interaction with 4-wire resistive for external protection devices. touchscreen. It enables the detection of 2 fingers on the The SX8651 is offered in two tiny packages: 3.0 mm x touchscreen and several gestures like the rotation and the 3.0 mm DFN and a 1.5 mm x 2.0 mm wafer-level chip-scale pinch/ stretch. package (WLCSP). This ultra low power touchscreen controller has been optimized for portable equipment where power and board- EVK CONTENT space are at a premium. The evaluation board It incorporates a highly accurate 12-bit ADC for data A USB cable to connect the board to the PC conversion and operates from a single 1.65 to 3.7V supply voltage. A CDROM with the installation files and the user guide The SX8651 features a built-in preprocessing algorithm for MINIMAL CONFIGURATION data measurements, which greatly reduces the host processing overhead and bus activity. This complete PC with MS windows 2000/XP touchscreen solution includes four user-selectable USB interface operation modes which offer programmability on different configurations such as conversion rate and settling time, RECOMMENDED READING thus enable optimization in throughput and power SX8651 Datasheet Revision V1.2/March 2012 Page 1 www.semtech.com 2010 Semtech Corp.
