This capacitive touch-sensing controller is optimised to replace mechanical buttons in front panels for industrial and consumer applications, portable medical devices, gaming devices and home automation systems. The low-power CY8CMBR2110 device supports up to 10 buttons and drives up to 10 LEDs with fully configurable LED effects.
Cypress also introduced the EZ-Click customizer tool, GUI-based software that combines device configuration, visual feedback, and production line testing for streamlined register configuration of the CY8CMBR2110 controllers, thereby accelerating time-to-market. Designers can use the tool to implement customised LED effects and buzzer output for audio feedback. Controllers in the Mechanical Button Replacement (MBR) family use Cypress’s SmartSense auto-tuning algorithm, which eliminates the requirement for manual system tuning and is the only solution that maintains optimal button performance during run-time.
“The market for front panel user interfaces in industrial, medical and consumer applications is huge and growing,” said Dirk Franklin, business unit director for Cypress’s CapSense solutions. “Designing a capacitive touch sensing user interface is not easy, but with our CapSense Express MBR family, backed by the support of our revolutionary new EZ-Click customiser tool and SmartSense auto-tuning technology, Cypress has delivered ease of design for sleek, reliable capacitive touch control panels. What we like to say about our new, button-replacement family is that ‘it just works!’”
The CapSense Express MBR family includes the CY8CMBR2016 matrix keypad solution, the CY8CMBR2010 ten-button controllers and the CY8CMBR2044 four-button hardware configurable controllers. Devices in the family offer supply current in run mode of 15 µA per button and a 100 nA Deep-Sleep mode. The devices operate over a 1.71V to 5.5V range, making them suitable for a wide range of regulated and unregulated battery applications, and enabling them to operate from a single coin cell battery. The family delivers robust sensing in noisy environments using Cypress’s patented CapSense Sigma Delta (CSD) sensing method, ensuring superior immunity to conducted and radiated noise. These devices also feature an
