MMA7455LR1 Description

Short technical summary and product information.

The MMA7455LR1 from Freescale Semiconductor is a low-power, low-profile capacitive micromachined accelerometer with digital output via I2C or SPI interfaces. It offers selectable sensitivity for acceleration ranges of ±2g, ±4g, and ±8g, making it versatile for various motion sensing applications.

This accelerometer features signal conditioning, a low-pass filter, and temperature compensation. It includes self-test capabilities for the Z-axis and supports pulse detection for quick motion recognition. The device operates within a low voltage range of 2.4V to 3.6V and includes a standby mode ideal for battery-powered electronics.

Packaged in a compact 3mm x 5mm x 1mm LGA-14 surface-mount package, the MMA7455LR1 is designed for robust performance with high shock survivability up to 5,000g. Its features make it suitable for applications such as image stabilization, freefall detection in HDDs and laptops, pedometers, and general motion sensing.

Key specifications include a sensitivity of 64 LSB/g in 10-bit mode and support for programmable threshold interrupts and level detection for motion recognition.
