IFXCY8CMBR3108-LQXI
Overview
The CY8CMBR3108-LQXI is a dedicated CapSense Express controller designed for implementing capacitive touch interfaces without the need for firmware development. This 8-input device utilizes the patented CSD sensing algorithm and SmartSense auto-tuning to handle varying board parasitics and environmental changes automatically. It operates over a wide voltage range of 1.8V to 5.5V and is optimized for low-power operation, consuming only 22 uA per sensor.
Why Choose This Part
The primary advantage is the configuration-based workflow that eliminates the need for complex C coding or firmware debugging. Integrated SmartSense technology simplifies hardware design by automatically tuning for optimal performance across manufacturing variations. Additionally, the device includes high-sink current GPOs for direct LED driving and flanking sensor suppression to prevent false triggers in dense layouts.
Applications
Key Specifications
Getting Started
Designers should use the EZ-Click Customizer tool to configure sensor parameters, LED behaviors, and I2C registers. Evaluation can be performed using the CY8CKIT-145-40XX or similar CapSense development kits from Infineon. The configuration is stored in on-board non-volatile memory, allowing the device to operate as a standalone controller or as an I2C slave to a host MCU.
