SCA8X0/21X0/3100 Series
General Description
1.1
Introduction
VTI Automotive Digital Accelerometer Platform is an accelerometer product concept based on VTI
capacitive 3D-MEMS technology. The VTI ADP platform integrates high accuracy micromechanical
acceleration sensing together with a flexible SPI digital interface. The products within the platform
range from single axis accelerometers into two or three axis accelerometers. Dual Flat Lead (DFL)
housing of the component guarantees robust operation over the product lifetime.
The products are designed, manufactured and tested for high stability, reliability and quality
requirements of automotive applications. The accelerometers have extremely stable output over
wide range of temperature, humidity and mechanical noise. The components are qualified against
AEC-Q100 standard and have several advanced self diagnostics features. The DFL housing is
suitable for SMD mounting and the component is compatible with RoHS and ELV directives.
This Product Family Specification describes the VTI Automotive Digital Accelerometer Platform
common characteristics and how to operate with the products. Detail product specification is
described in individual data sheets of each product.
