CY8CMBR3102-SX1IT

CY8CMBR3102-SX1IT is a CapSense® Express™ controller with smartsense auto-tuning - 16 buttons, 2 sliders, proximity sensor. It enables advanced, yet easy-to-implement, capacitive touch-sensing user interface solutions. This register-configurable family, which supports up to 16 capacitive sensing inputs, eliminates time-consuming firmware development. This controller is ideal for implementing capacitive buttons, sliders, and proximity-sensing solutions with minimal development-cycle times. It features an advanced analogue sensing channel and the Capacitive Sigma Delta PLUS (CSD PLUS) sensing algorithm, which delivers a signal-to-noise ratio (SNR) of greater than 100:1 to ensure touch accuracy even in extremely noisy environments. This controller is enabled with Cypress’s SmartSense™ Auto-tuning algorithm, which compensates for manufacturing variations and dynamically monitors and maintains optimal sensor performance in all environmental conditions.
