CY8CMBR2010

■ Ensures portability of the user interface design.

Configuring the CY8CMBR2010

■ Compensates Printed Circuit Board (PCB) variations, Device

process variations, and PCB vendor changes.

The CY8CMBR2010 device features are configured using

external resistors.

General-Purpose Outputs

■ GPOx pin outputs are strong drive^[3]

The resistors on the hardware configurable pins are determined

by the device upon power-on.

The Appendix on page 28 gives the matrix of features enabled

using different external resistor configurations.

■ The GPOx is controlled by the corresponding CSx

To know more about the required settings for your design, refer

to the CY8CMBR2010 Design Guide.

■ Active low output – supports sinking configuration for LEDs

(see Figure 3)

■ If CSx is disabled (grounded), then the corresponding GPOx

must be left floating

Device Features

CapSense Buttons

■ A 5-ms pulse is sent after 350 ms (if Noise Immunity level is

“Normal”) / 1000 ms (if Noise Immunity level is “High”) after

power-up on the GPOx if the CSx fails the System Diagnostics

■ Supports up to ten CapSense buttons.

■ Ground the CSx pin to disable CapSense button input.

Figure 3. Example of GPO0 Driven by CS0

■ A 2.2 nF (±10%) capacitor must be connected on the C_MODpin

for proper CapSense operation.

Button

Sensor

Touched

Released

■ For proper CapSense operation, ensure C_Pof each button is

less than 40 pF.

SmartSense™ Auto-Tuning

CS0

■ Supports auto-tuning of CapSense parameters

■ No manual tuning required; all parameters are automatically

tuned by the device.

GPO0

■ Reduces the design cycle time.

❐ No manual tuning.

Table 2. Advanced Features Supported by CY8CMBR2010

Feature

Benefit

Toggle ON/OFF

Button retains state on touch (ON/OFF)

Flanking Sensor Suppression (FSS)

Noise Immunity

Helps in distinguishing closely spaced buttons

Improves device immunity to external noise (such as RF noise)

Gives an LED effect on button release

LED ON Time

Button Auto Reset

Disables false output trigger, due to conducting object placed close to button

Provides visual effects to design at power-on

Power-on LED Effects

Analog Voltage Support

LED Backlighting

External resistors can be used with GPOs to generate analog voltage output

Common GPO available for LED drive if Analog Voltage Support enabled

Sensitivity Control for CS0 Button and Debounce Useful for special function buttons such as power button

Control for CS0 Button

System Diagnostics

Serial Debug Data

Support for production testing and debugging

Support for production testing and validating design

Low Power Sleep Mode and Deep Sleep Mode Low power consumption

Note

3. When a pin is in strong drive mode, it is pulled up to V when the output is HIGH and pulled down to Ground when the output is LOW.
