MMA8652FCR1

MMA8652FCR1 is a 3-axis, 12-bit, digital accelerometer. It is an intelligent, low-power, three-axis, capacitive micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user-programmable options, configurable to two interrupt pins. Embedded interrupt functions enable overall power savings, by relieving the host processor from continuously polling data. There is access to either low-pass or high-pass filtered data, which minimizes the data analysis required for jolt detection and faster transitions. The device can be configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions, enabling the MMA8652FC to monitor inertial events while remaining in a low-power mode during periods of inactivity.

• Supply voltage range from 1.95 to 3.6V (VDD = 2.5V, VDDIO = 1.8V, T = 25°C)
• Output data rates (ODR) from 1.56Hz to 800Hz
• I²C digital output interface with programmable interrupts
• Four embedded channels of configurable motion detection (Freefall, motion, pulse, transient)
• Orientation (Portrait/Landscape) detection with programmable hysteresis
• Configurable automatic ODR change triggered by the auto-wake/sleep state change
• 32-sample FIFO, self-test
• High-pass filter data available per sample and through the FIFO
• ODR accuracy is ±3.1% typ (VDD = 2.5V, VDDIO = 1.8V, TA = 25°C)
• DFN-10 package, temperature range from -40°C to +85°C
