Description
The ML8953 is a 3-axis accelerometer based on the piezo-resistive sensing principle and that provides data output in a digital format.
The internal logic circuitry consists of a MCU with embedded Flash ROM, and supporting both I2C and SPI interface. Flexible addresses simplify connectivity to the host controller.
The internal MCU offers several features that minimize work load from the host controller.
The internal Flash ROM stores factory calibration data, taking the additional calibration steps off the customer’s manufacturing line.
Features:
o MEMS-based 3D Accelerometer
o Detects static and dynamic acceleration on three orthogonal axes
o Digital output: temperature, acceleration (component and vector), roll/pitch angles
o Factory calibration and internal temperature compensation
o Automatic measurement, continuous or interruption mode, polling mode, average output
o Programmable trigger threshold of acceleration levels
Main Specifications:
o Detection range: -3g to +3g (acceleration)
-180o to +180o (roll/pitch angle)
o Sensitivity: 10mg/bit (acceleration)
