APPLICATIONS
MXC6202xJ/K FUNCTIONAL BLOCK DIAGRAM
The MXC6202xJ/K is optimized for motion-sensing and
tilt-sensing applications such as gesture recognition,
menu and screen navigation and HDD protection for
consumer devices including:
Information Appliances: – Cell Phones, PDA’s, MP3’s
and static acceleration (e.g. gravity). Its design is
based on heat convection and requires no solid proof
mass.
Consumer Products: –Pedometers, Blood Pressure
Monitor, Digital Cameras
Gaming Products:– Joysticks, RF Interfaces, Handheld
This design eliminates the stiction problems
associated with legacy technologies. MEMSIC’s solid
state design leads to significantly lower failure rates in
customer applications as well as lower loss due to
handling during manufacturing and assembly
processes.

GPS: – Electronic Compass Tilt Correction
GENERAL DESCRIPTION
The MXC6202xJ/K is an ultra low cost; dual axis
accelerometer fabricated on a standard, submicron
CMOS process. It is a complete sensing system with
on-chip mixed signal processing and integrated I2C
(Inter IC) bus, allowing the device to be connected
directly to a microprocessor eliminating the need for
A/D converters or timing resources. It measures
acceleration with a full-scale range of ±2 g and a
sensitivity of 400counts/g @3.0 V at 25°C. It can
measure both dynamic acceleration (e.g. vibration)
It is packaged in a small low profile LCC surface
mount package (5.5 mm x 5.5 mm x 1.40 mm with a
maximum height of 1.50 mm) and is available for
operating temperature ranges of -10°C to +70°C (J)
and -40°C to +85°C (K).
The maximum noise floor is 2.0 mg/ Hz allowing
signals below 2milli-g to be resolved at 1 Hz
bandwidth.
