Technical Data
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.
• Tilt Measurement

EXTERNAL COMPONENTS
The MMA6700EG requires minimum external components. Aside from a supply bypass capacitor, two 1 μF capacitors provide
filtering for the internal analog and digital power supply rails, while a third, 100 nF filter capacitor is required for the internal voltage
reference. This circuit configuration is illustrated in Figure 2. Redundant pins are provided for the internal voltage reference and
analog supply rails. In safety critical applications, these pins may be connected to separate external capacitors to guard against
circuit malfunction in the event of a fault such as an open filter capacitor connection. An internal monitor detects an open digital
supply rail filter capacitor condition, which puts the device into reset should this fault occur.
