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

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
