CY8CMBR2044 | Cypress Semiconductor


CY8CMBR2044 solution supports up to 4-buttons and is quickly configured in hardware, eliminating the need for software tools, firmware development and chip programming. This solution supports direct LED drive and configurable LED effects at Power-on. Enabled with Cypress’s revolutionary SmartSense™ Auto-tuning algorithm, it eliminates the need for manual tuning. This advancement in solution simplicity enables designers to include a capacitive sensing UI without risk to the end product development schedule, offering a faster time-to-market. Essentially the UI design task has been reduced to the PCB layout of the sensor board – the CapSense Express controller handles rest.
