CapSense Express™ -8 Configurable IOs

Features

Overview

■ 8 configurable IOs supporting

❐ CapSense buttons

❐ LED Drive

❐ Interrupt outputs

❐ WAKE on interrupt input

❐ User defined input or output

The CapSense Express^TMcontroller allows the control of 8 IOs

configurable as capacitive sensing buttons or as GPIOs for

driving LEDs or interrupt signals based on various button

conditions. The GPIOs are also configurable for waking up the

device from sleep based on an interrupt input.

The user has the ability to configure buttons, outputs, and

parameters through specific commands sent to the I²C port. The

IOs have the flexibility in mapping to capacitive buttons and as

standard GPIO functions such as interrupt output or input, LED

drive and digital mapping of input to output using simple logical

operations. This enables easy PCB trace routing and reduces

the PCB size and stack up. CapSense Express products are

designed for easy integration into complex products.

■ 2.4V to 5.25V operating voltage

■ Industrial temperature range: –40°C to +85°C

■ I²C slave interface for configuration

❐ Selectable to 50 kHz,100 kHz and 400 kHz

■ Reduce BOM cost

❐ Internal oscillator - no external oscillators or crystal

❐ Free development tool - no external tuning components

Architecture

The logic block diagram illustrates the internal architecture of

CY8C20180.

■ Low operating current

❐ Active current: continuous sensor scan:1.5 mA

❐ Sleep current: no scan, continuous sleep: 2.6 uA

The user can configure registers with parameters needed to

adjust the operation and sensitivity of the CapSense system.

CY8C20180 supports a standard I²C serial communications

interface that allows the host to configure the device and to read

sensor information in real time through easy register access.

■ Available in 16-pin COL and 16-pin SOIC packages

The CapSense Express Core

The CapSense Express Core has a powerful configuration and

control block. It encompasses SRAM for data storage, an

interrupt controller, sleep and watchdog timers. System

resources provide additional capability, such as a configurable

I²C slave communication interface and various system resets.

The Analog System is composed of the CapSense PSoC block

which supports capacitive sensing of up to eight inputs.
