It has proven its capability to deliver leading edge quality and services to fulfill the needs of even the most demanding automotive customers. It is SMSC s proven total approach to true automotive-grade quality. SMSC s TrueAuto robustness begins with the design for reliability techniques within the silicon IC itself. Automotive-grade excellence and testability are designed into the IC. The IC is fully characterized over many operating parameters to prove the quality of the design under various conditions. It meets or exceeds automotive reliability standards (like AEC-Q100) and customer specific requirements. In addition, extensive technologies and processes, such as enhanced monitors are used in fabrication of TrueAuto products in order to continuously drive improvements in accordance with SMSC s zero Defects per Million (DPM) goals. 80 ARKAY DRIVE, HAUPPAUGE, NY 11788 (631) 435-6000, FAX (631) 273-3123 Copyright 2010 SMSC or its subsidiaries.
