DS40001667E-page 14 Advance Information  2012-2017 Microchip Technology Inc.
3.0 SYSTEM ARCHITECTURE
MGC3X30 are mixed-signal configurable controllers.
The entire system solution is composed of three main
building blocks (see Figure 3-1):
• MGC3X30 Controller
• GestIC
®
Library
• External Electrodes
3.1 MGC3X30 Controller
The MGC3X30 feature the following main building
blocks:
• Low Noise Analog Front End (AFE)
• Digital Signal Processing Unit (SPU)
• Communication Interfaces
The MGC3X30 provide a transmit signal to generate
the E-field, conditions the analog signals from the
receiving electrodes and processes these data digitally
on the SPU. Data exchange between the MGC3X30
and the host is conducted via the controller’s
communication interface or the Gesture Port. For
details, please refer to Section 4.0 “Functional
Description”.
3.2 GestIC
®
Library
The embedded GestIC Library is optimized to ensure
continuous and real-time free-space Gesture
Recognition and Motion tracking (MGC3130)
concurrently. It is fully-configurable and allows required
parameterization for individual application and external
electrodes.
3.3 External Electrodes
Electrodes are connected to MGC3X30. An electrode
needs to be individually designed following the guide
lines from the ‘GestIC Design Guide’ for optimal E-field
distribution and detection of E-field variations inflicted
by a user.
