High Accuracy Low g Inertial Sensor

MEMS Sensing, State Machine ASIC

The MMA6700EG series is a dual axis, Low g, XY-axis sensor based on

Freescale’s HARMEMS technology with an embedded DSP ASIC allowing for

additional processing of the digital or analog signals.

Features

•

XY-axis of sensitivity in one device

•

10- or 11-bit digital data output

•

±3.5 g or ±5 g full-scale range per axis

- MMA6700EG: ±3.5 g (11-bit data sensitivity = 3.43 mg/digit typical at 25º C)

- MMA6701EG: ±5 g (11-bit data sensitivity = 4.91 mg/digit typical at 25ºC)

•

SPI-compatible serial interface

•

Bidirectional internal self-test

•

On-chip temperature sensor and voltage regulator

•

Support for signed or unsigned output data

•

Selection of integrated signal conditioning low-pass filters

•

Capture/hold input for system-wide synchronization support

•

3.3 V or 5 V single supply operation

•

Ratiometric analog voltage output

•

Traceability through programmable registers, 3 8-bit.

•

Customer-assigned one-time-programmable Registers (2 8-bit Registration)

•

Minimal external component requirements

•

Wide operating temperature range from -40ºC to +125ºC

•

20-pin SOIC wide-body RoHS-compliant package

•

Minimum external components, 4 capacitors

Typical Applications

•

With a +3.5 g or +5 g full scale range, the newly designed, high accuracy

sensor enables electronic stability control (ESC) designers to accommodate

higher original signal noise level without sacrificing resolution.
