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

GENERAL DESCRIPTION
The MXC6232xG/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 0C to +70C (G/H) and-40C to +85C(M/N).
The MXC6232xG/H/M/N is 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 I2C bus, allowing the
device to be connected directly to a microprocessor
eliminating the need for A/D converters or timing resources.
The MXC6232xG/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 25C. It can measure both
dynamic acceleration (e.g. vibration) and static acceleration
(e.g. gravity). The MXC6232xG/H/M/N design is based on
heat convection and requires no solid proof mass.
The MXC6232xG/H/M/N provides I2C digital output with
400 KHz, fast mode operation.

The maximum noise floor is 1 mg/
allowing signals
below 1mg to be resolved at 1 Hz bandwidth
