GENERAL DESCRIPTION
The MXC6202G/H/M/N are low cost, dual axis
accelerometers fabricated on a standard, submicron CMOS
process. It is a complete sensing system with on-chip
mixed signal processing and integrated I
2
C bus, allowing
the device to be connected directly to a microprocessor
eliminating the need for A/D converters or timing
resources. The MXC6202G/H/M/N measures acceleration
with a full-scale range of
±2
g
and a sensitivity of
512counts/g (G/M) or 128counts/g (H/N) @3.0 V at 25
°C
.
It can measure both dynamic acceleration (e.g. vibration)
and static acceleration (e.g. gravity). The
MXC6202G/H/M/N design is based on heat convection and
requires no solid proof mass.
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 patent rights of MEMSIC.
MXC6202G/H/M/N FUNCTIONAL BLOCK DIAGRAM
This design eliminates the stiction problems associated with
legacy technologies and provides shock survival greater
than 50,000g’s. Memsic’s solid state design leads to
significantly lower failure rates in customer applications
and lower loss due to handling during manufacturing and
assembly processes
The MXC6202G/H/M/N is packaged in a hermetically
sealed, low profile LCC surface mount package (5 mm x 5
mm x 1.55 mm) and is available in operating temperature
ranges of 0°C to +70°C (G/H) and-40°C to +85°C(M/N).
The MXC6202G/H/M/N provides two I
2
C digital outputs
with 400 KHz, fast mode operation.
The maximum noise floor is 1 mg/
Hz
allowing signals
below 1 milli-g to be resolved at 1 Hz bandwidth
