Semtech SX9300EVKA Dual Channel Capacitive Touch Sensor Development and Evaluation Kit
Product Description
The Semtech SX9300EVKA is a professional-grade touch sensor development and evaluation kit featuring the SX9300 dual channel capacitive touch sensor controller. This device specializes in accurately discriminating between inanimate objects and human body proximity, crucial for Specific Absorption Rate (SAR) compliance and RF emission power control in portable electronic devices.
Key technical features include:
- Dual channel capacitive sensor with on-chip auto-calibration for sustained sensitivity across diverse temperature, humidity, and noise environments
- Operating voltage range from 2.7 V to 5.5 V
- Host-compatible I2C serial communication bus operating from 1.65 V to 5.5 V, including compatibility with 1.8 V hosts for flexible integration
- NIRQ interrupt output that signals proximity detection, enabling precise proximity distance estimation or simple detection indication
- Dedicated TXEN transmit enable pin synchronizes measurements with RF transmissions, optimizing power consumption and noise immunity
The device enables system designers to integrate highly reliable human presence detection, which is essential for meeting strict SAR regulatory standards and enhancing biomedical engineering applications that require minimized electromagnetic exposure. This kit is widely adopted for development in fields involving biotechnology equipment design, molecular diagnostics instrumentation, and bioprocessing controls, where safe, low-emission electronic interaction is critical.
The package includes one SX9300EVKA evaluation board and a development tools CD for firmware and software support. This touch sensor controller kit is vital for researchers and engineers focused on innovations in live-cell imaging instruments, biopharmaceutical production electronics, and synthetic biology device development, where precise proximity sensing and RF emission management contribute to safer and more efficient laboratory technologies.
Worldwide shipping is available for this laboratory-grade development solution.
