MMA8450Q规格书详情
3-Axis, 8-bit/12-bit Digital Accelerometer
The MMA8450Q is a smart low-power, three-axis, capacitive micromachined accelerometer featuring 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data.
Features
• 1.71V to 1.89V supply voltage
• ±2g/±4g/±8g dynamically selectable full-scale
• Output Data Rate (ODR) from 400 Hz to 1.563 Hz
• 375 μg/√Hz noise at normal mode ODR = 400 Hz
• 12-bit digital output
• I2C digital output interface (operates up to 400 kHz Fast Mode)
• Programmable two interrupt pins for eight interrupt sources
• Embedded four channels of motion detection
– Freefall or motion detection: 2 channels
– Pulse Detection: 1 channel
– Transient (Jolt) Detection: 1 channel
• Orientation (Portrait/Landscape) detection with hysteresis compensation
• Automatic ODR change for auto-wake and return-to-sleep
• 32 sample FIFO
• Self-Test
• 10,000g high shock survivability
• RoHS compliant
Typical Applications
• Static orientation detection (portrait/landscape, up/down, left/right, back/front position identification)
• Real-time orientation detection (virtual reality and gaming 3D user position feedback)
• Real-time activity analysis (pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup)
• Motion detection for portable product power saving (auto-sleep and auto-wake for cell phone, PDA, GPS, gaming)
• Shock and vibration monitoring (mechatronic compensation, shipping and warranty usage logging)
• User interface (menu scrolling by orientation change, tap detection for button replacement
