MGC3130-I/MQ

Specialized Overview

The MGC3130-I/MQ is a 28-pin QFN electrical-field-based 3D gesture controller from Microchip Technology. It operates on a single 3.3V supply and supports an industrial temperature range of -20°C to +85°C. The device features five receive channels and one transmit channel, enabling detection ranges from 0 to 10 cm with up to 200 positions per second and 150 dpi spatial resolution. Carrier frequencies range from 44 kHz to 115 kHz. Power modes include processing at 20 mA, programmable self wake-up at 110 µA, and deep sleep at 9 µA. It includes an I²C interface for configuration and sensor output streaming.

Specialized Feature Summary

• Integrated Colibri Gesture Suite enables on-chip 3D hand gesture recognition and x, y, z positional data tracking without host processing.
• Advanced signal processing unit provides high receiver sensitivity below 1 fF with automatic frequency hopping for noise immunity.
• Supports field upgradeable GestIC libraries via I²C for flexible gesture definition and system customization.
• Includes gesture port pins for direct mapping of events to external I/O signals, simplifying embedded integration.

Specialized Applications

• Audio products and control interfaces
• Home automation and white goods
• Medical products and industrial switches

Specialized Procurement Notes

Verify the specific package type and operating temperature grade against project requirements before ordering. Confirm that the I²C pull-up resistor values match the design specifications for reliable communication. Ensure the electrode design adheres to the GestIC Design Guide to maintain optimal sensitivity and performance levels.

Specialized Selection Notes

Select the MGC3130 variant when 3D position tracking alongside gesture recognition is required. The MGC3030 offers gesture recognition only without positional data. Consider the QFN package for compact designs requiring a 0.5 mm pitch. Verify power consumption constraints to ensure the deep sleep mode meets battery life expectations.

Specialized Part Context
