Evaluation Boards - Sensors

The KIT3468MMA7455L is a high-performance, low-power 12-bit digital accelerometer designed for mobile phone applications. It is used to detect the magnitude and direction of static and dynamic acceleration in three perpendicular axes, and produces linear acceleration measurements with up to 20g dynamic range. It operates at a low frequency and consumes minimal power which makes it ideal for battery-operated mobile phone applications.

The KIT3468MMA7455L includes an I2C digital interface which allows it to communicate with other components on the system. The interface supports up to 8 MHz of maximum data rate and supports up to three 8-bit registers. With the help of the user-friendly software, the register functions can be configured to select sensing range, output data rate, interrupt enable/disable, and other settings.

An external 16-bit memory can also be connected to the interface, allowing the user to set up the desired settings for the KIT3468MMA7455L without needing a secondary microcontroller. The KIT3468MMA7455L also supports an integrated temperature sensor, allowing it to be used for temperature monitoring applications.

Application Field

The KIT3468MMA7455L is used in a wide variety of applications. It is most commonly used in consumer electronics such as mobile phones and portable gaming devices. It can also be used in automotive applications, as it can detect the amount and direction of acceleration applied to a vehicle. It can also be used in medical equipment to detect and monitor various body movements.

Working Principle

The KIT3468MMA7455L works by measuring total acceleration in the three perpendicular axes, and then converting the readings to three independent linear acceleration readings. An internal Digital Signal Processor (DSP) is used to calculate the measurements taken from the force-sensing resistors. The measurements are then output to the registers which can be read using the I2C interface.

The sensing range of the KIT3468MMA7455L can be configured by setting the appropriate register. The default range is up to 20g, but the user can configure the device to detect up to 40g range. The output data rate can also be configured with the set registers. The data rate of the device ranges from 0.781 Hz up to 800 Hz.

The power consumption of the KIT3468MMA7455L is very low, so it is suitable for use in battery-operated devices. The operating voltage of the device is between 1.8 V to 3.6 V. The typical current consumption of the KIT3468MMA7455L is 0.5 μA when the device is operating at full speed.

As a general-purpose accelerometer, the KIT3468MMA7455L provides a reliable solution for detecting and measuring acceleration in a variety of applications. It is easy to set up and configure, and its low power consumption makes it ideal for portable devices.
