1 Introduction

This document describes the evaluation kits of the:
- SX8634 (proximity, buttons and slider)
- SX8635 (proximity, buttons and wheel)
- SX8644 (buttons and slider)
- SX8645 (buttons and wheel)
In this user guide the term EVK refers to the SX8634EVK, SX8635EVK SX8644EVK and SX8645EVK
The SX863x and SX864x family (see references [1] to [13]), is an ultra low power, fully integrated 12 (or 8) -channel
solution for capacitive touch-buttons, slider and wheel and proximity applications with enhanced LED drivers. The
SX863x/4x family features dedicated capacitive sense inputs (that requires no external components) in addition to 8
general purpose I/O ports (GPIO). Each GPIO is typically configured as LED driver with independent PWM source
for enhanced lighting control such as intensity and fading. SX863x offers additionally proximity detection.
