They enable usercommand input with natural hand and finger movements. Applying the principles of electrical nearfield sensing, the MGC3X30 contain all the building blocks to develop robust 3D gesture input sensing systems. Implemented as a low-power mixed-signal configurable controller, they provide a large set of smart functional features with integrated signal driver,a frequency adaptive input path for automatic noise suppression and a digital signal processing unit. Microchips on-chip Colibri Suite obsoletes processing needs at the host, reduces system power consumption resulting in low software development efforts for short time-to-market success. The MGC3XXX family represents a unique solution that provides gesture information of the human hand in real time. Dedicated chip family members add position data, touch or multi touch information to the free space gesture sensing.The MGC3XXX allow the realization of a new generation of user interfaces across various industry markets.傲壹电子(AO-Electronics) 官网：/main.php 中文网：MGC3030主要特性: Recognition of 3D Hand Gestures and x, y, z Positional Data (MGC3130) Proximity and Touch Sensing Built-in Colibri Gesture Suite (running on chip) Advanced 3D Signal Processing Unit Detection Range: 0 to 10 cm Receiver Sensitivity: 1 fF Position Rate: 200 positions/sec Spatial Resolution: up to 150 dpi Carrier Frequency: 44 kHz to 115 kHz Channels Supported:- Five receive (Rx) channels- One transmit (Tx) channel On-chip Auto Calibration Low Noise Radiation due to Low Transmit Voltage and Slew Rate Control Noise Susceptibility Reduction:- On-chip analog filtering- On-chip digital filtering- Automatic frequency hopping Enables the use of Low-Cost Electrode Material including:- Printed circuit board- Conductive paint- Conductive foil- Laser Direct Structuring (LDS)- Touch panel ITO structures Field Upgrade Capability Operating Voltage: 3.3V (+/-5%) (single supply) Temperature Range: -20 to +85MGC3030功耗特性: Variety of Several Power Operation modes include:- Processing mode: 20 mA 3.3V, typical- Programmable Self Wake-up: 110 A 3.3V- Deep Sleep: 9 A 3.3V, typicalMGC3030外设特性: 1x I2C Interface for Configuration and Sensor output streaming Five Gesture Port pins for individual mapping of gesture to EIOsMGC3030应用: Audio Products Notebooks/Keyboards/PC Peripherals Home Automation White Goods Switches/Industrial Switches Medical Products Game Controllers Audio Control图1.
