CapSense® Controllers | Cypress
Cypress’s CapSense® technology consists of an advanced analog sensing channel and the Capacitive Sigma Delta (CSD) sensing algorithm. This patented algorithm provides high sensitivity to ensure accurate touch in noisy environments, proximity distances of up to 30 cm, and allows for fast scan times. Cypress has also developed the SmartSense™ algorithm, which provides for robust noise immunity and adaptation to changing environments, without the need for manual tuning.
Cypress’s CapSense® portfolio consists of the Mechanical Button Replacement (MBR) family. The MBR family requires no firmware development and allows for easy development for Capacitive sensing systems using Cypress’s GUI-based software tool, EZ-Click™. The latest solution in the MBR family is the CapSense MBR3 device.
Features supported by the CapSense MBR3 include:
- Buttons and sliders (up to 16 GPIOs for buttons or slider use)
- General Purpose Output pins (GPOs) that can be used for external feedback (such as LEDs and buzzers) when the capacitive button is touched
- Register configurable, which can be accomplished using Cypress’s GUI-based software tool, EZ-Click™
- Pre-programmed firmware (no need to develop firmware)
- SmartSense™ auto tuning that allows your CapSense® system to adapt to changing environments, variations in PCB manufacturing, and eliminates the need for manual tuning.
- Ultra-low power with industry’s widest voltage range
- Industry’s best solution for liquid tolerance to prevent false touches in wet/moist environments
- Industry’s best solution for proximity sensing to replace external sensors (for example, IR sensors in Smartphones)
The CapSense® technology can also be enabled in Cypress’s Programmable System on Chip (PSoC®) devices. PSoC® is the world's only programmable embedded System-on-Chip integrating an MCU core, high-performance Programmable Analog Blocks, PLD-based Programmable Digital Blocks, and Programmable Interconnect and Routing. This device allows for the user to implement Digital and Analog features, while also having the option to use CapSense®. For more information on these devices, please visit the PSoC Webpage here.
