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)

MXC6202xJ/K FUNCTIONAL BLOCK DIAGRAM
and static acceleration (e.g. gravity). Its design is
based on heat convection and requires no solid proof
mass.
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.
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.
Information furnished by MEMSIC is believed to be accurate and reliable.
However, no responsibility is assumed by MEMSIC for its use, or for any
infringements of patents or other rights of third parties which may result from
its use. No license is granted by implication or otherwise under any patent or
