MGC3130
4.0
FUNCTIONAL DESCRIPTION
Microchip Technology’s MGC3130 configurable
controller uses up to five E-field receiving electrodes.
Featuring a Signal Processing Unit (SPU), a wide
range of 3D gesture applications are being pre-
processed on the MGC3130, which allows short
development cycles.
Always-on 3D sensing, even for battery-driven mobile
devices, is enabled due to the chip’s low-power design
and variety of programmable power modes. A Self
Wake-up mode triggers interrupts to the application
host reacting to interaction of a user with the device
and supporting the host system in overall power
reduction.
Featuring a programmable 4-pin digital interface, the
MGC3130 matches a multitude of hardware
requirements. Developers have the choice of data
exchange via I

master-slave architecture between two MGC3130
devices to add an additional sensing area (e.g., Two-
devices to add an additional sensing area (e.g., Two-
Zone Design) or a single MGC3130 and another circuit
with a corresponding interface, such as a touch screen
controller.
GestIC sensing electrodes are driven by a low-voltage
signal with a frequency in the range of 100 kHz, which
allows their electrical conductive structure to be made
of any low-cost material. Even the reuse of existing
conductive structures, such as a display’s ITO coating,
is feasible, making the MGC3130 an overall, very cost-
effective system solution.
