MCHPCAP1128-1-BP-TR
Overview
The CAP1128-1-BP-TR is an 8-channel capacitive touch controller designed for creating reliable human-machine interfaces. It supports proximity detection and features two integrated LED drivers with PWM control, allowing for synchronized visual feedback. The device communicates via I2C, SMBus, or SPI and includes a dedicated wake output for low-power operation.
Why Choose This Part
It offers superior noise immunity through analog filtering and automatic recalibration to compensate for environmental changes or parasitic capacitance. The device is highly power-efficient, consuming only 5uA in deep sleep while maintaining the ability to wake the host processor via a dedicated pin.
Applications
Key Specifications
Getting Started
Designers can evaluate this part using the CAP1128 Evaluation Board (EVB-CAP1128). Firmware development is simplified by the Microchip CAP11xx library, and hardware integration is straightforward due to the flexible I2C/SPI interface and the small 4x4mm QFN package.
