Overview

The CY8CMBR2010 CAPSENSE? Express family supports up to ten capacitive touch-sensing channels that enable ten buttons/LEDs. It is hardware-configured and supports direct LED drive and effects at power-on. Infineon's SmartSense auto-tuning algorithm eliminates the need for system tuning enabling designers to reduce the UI design task to the PCB layout of the sensor board ¨C the CAPSENSE? Express controller handles the rest.

Key Features

  • Up to ten CAPSENSE? buttons
  • Voltage range 1.71 V to 5.5 V
  • No programming required
  • SmartSense auto-tuning
  • 15 ¦ÌA per button in run mode
  • 100 nA in the deep sleep mode
  • Robust noise-immunity

About

About CY8CMBR2010

The CY8CMBR2010 CAPSENSE? Express capacitive touch-sensing controller saves time and money, quickly enabling a capacitive touch-sensing user interface in your design. It is a hardware-configurable device and does not require any software tools, firmware coding, or device programming. This device is enabled with Infineon¡¯s revolutionary SmartSense auto-tuning algorithm. SmartSense auto-tuning ends the need to manually tune the user interface during development and production ramp. This speeds the time to volume and saves valuable engineering time, test time, and production yield loss.

CAPSENSE? touch-sensing buttons

The CY8CMBR2010 CAPSENSE? controller supports up to ten capacitive touch-sensing buttons and ten general purpose outputs (GPO). The GPO is an active-low output controlled directly by the CAPSENSE? input making it ideal for a wide variety of consumer, industrial, and medical applications. The wide operating range of 1.71 V to 5.5 V enables unregulated battery operation, further saving component cost. The same device can also be used in different applications with varying power supplies.

Noise Immunity

The CY8CMBR2010 CAPSENSE? Express family includes noise immunity and FSS. Noise immunity improves the immunity of the device against radiated and conducted noise such as audio and radio frequency (RF) noise. FSS provides robust sensing even with closely spaced buttons. FSS is a critical requirement in small form factor applications.?

Power-on LEDs

Power-on LED effects provide visual feedback to the design at power-on. This improves the aesthetic value of the end product. System diagnostics test for design faults at power-on and report any failures. This simplifies production line testing and reduces manufacturing costs. Serial debug data output gives critical information about the design such as button CP and signal-to-noise ratio (SNR). This further helps in production line testing.
