Overview

Cypress’ PSoC mixed-signal arrays are programmable systems-on-chips (SOCs) that integrate a microcontroller and the analog and digital components that typically surround it in an embedded system.  A single PSoC device can integrate as many as 100 peripheral functions with a microcontroller, saving you design time, board space, power consumption, and from 5 cents to as much as $10 in system costs.

The CapSense Express Family, supported by PSoC Express™ Visual Embedded System Design Tool and the CapSense Express Configuration Tool, is the quickest and easiest to use for touch sensing functionality. The CapSense Express family supports up to ten general purpose I/Os for buttons, multi-segment sliders, LEDs, and other general purpose functions, all configured via I2C registers.

A single Capsense device can replace dozens of mechanical switches and controls with a simple touch-sensitive interface. Capsense-based "button" and "slider" controls are more reliable than their mechanical counterparts because they are not prone to environmental wear-and-tear that effects most buttons and switches.
