Freescale Sensing Solutions
Freescale's Sensing Solutions go far beyond a sensor translating a signal – it's enabling greater levels of sensing context and intelligence. By increasing levels of modular integration with multiple sensor inputs, logic and other building blocks, Freescale brings greater value and decision making to the overall sensing solution.
Sensing Solutions - Accelerometers
Freescale Accelerometers are designed for end products and embedded systems that require measurement of forces resulting from fall, orientation, tap, double tap, tilt, jolt, motions, positioning, shake, shock or vibration.
Key Accelerometers in the Freescale Family
MMA7660FC: 3-axis, 6-bit digital output (I2C), very low power, low profile capacitive micro machined accelerometer featuring a low pass filter, compensation for 0g offset and gain errors.
MMA8450Q: 3-axis, 12-bit digital output , intelligent low power and noise accelerometer. It is packed with many flexible user programmable embedded functions that are available with two configurable interrupt pins.
MMA8451Q, MMA8452Q, MMA8453Q: Freescale's MMA8451, 2, 3 are extremely low power, 3-axis accelerometers offering a pin compatible family with a broad range of resolution (14-bit to 10-bit) and embedded features to select sophisticated system efficient features and configurable accurate motion analysis.
MMA8652FC: The 12-bit accelerometer has industry leading performance in a small 2 x 2 x 1 mm DFN package. This accelerometer is packed with embedded functions that include flexible user-programmable options and two configurable interrupt pins. Overall power savings is achieved through inertial wake-up interrupt signals that monitor events and remain in a low-power mode during periods of inactivity.
FXLS8471Q: The FXLS8471Q accelerometer is highly versatile for industrial and consumer high-performance low-g applications that offer noise density, board mount offset, temperature performance and sensitivity. Integrated motion detection features include tilt, shake and tap detection with a new vector magnitude output that simplifies implementation and reduces power consumption. This new FXLS8471Q accelerometer has a SPI interface that is pin-compatible with Freescale’s industry-leading I2C accelerometer portfolio.
MMA955xL: Freescale’s MMA955xL intelligent motion sensing platform is an industry first with integration of a MEMS accelerometer, a 32-bit embedded ColdFire microcontroller, flash memory and a dedicated architecture to manage other sensors.
Key Proximity Sensors in the Freescale Family
MPR03x: The MPR03X is an Inter-Integrated Circuit Communication (I2C) driven Capacitive Touch Sensor Controller, optimized to manage two electrodes with interrupt functionality, or three electrodes with the interrupt disabled. When using an I2C protocol devices require separate addresses as no chip select line is available. Thus, in order to use two MPR03x devices in the same system the MPR031 and MPR032 are each available where different I2C addresses are assigned to each part number.
MPR121: The MPR121 is the second generation sensor controller after the initial release of the MPR03x series devices. The MPR121 will feature increased internal intelligence in addition to Freescale's second generation capacitance detection engine.
FXOS8700CQ: The 6-axis sensor combines industry leading accelerometer and magnetometer sensors in a small 3 x 3 x 1.2 mm QFN plastic package. The 14-bit accelerometer and 16-bit magnetometer are combined with a high-performance ASIC to enable an eCompass solution capable of a typical orientation resolution of 0.1 degrees and sub 5 degree compass heading accuracy for most applications.
MAG3110: is a small, low-power digital 3-D magnetic sensor with a wide dynamic range to allow operation in PCBs with high extraneous magnetic fields. The MAG3110 magnetometer measures the three components of the local magnetic field which will be the sum of the geomagnetic field and the magnetic field created by components on the circuit board.
MPL3115A2: Freescale's MPL3115A2 provides highly precise pressure and altitude data with variable sampling rate capability. It has very low-power consumption, smart features and requires zero data processing for mobile devices, medical and security applications
