LIN Slave Node Design for Wireless Applications
As in-vehicle networking is becomes more prevalent in today’s vehicles the network complexity grows and  so does the wiring and cost associated with each subsequent network. A more simplified approach must be implemented in order to achieve the networking functionality required without ‘breaking the bank’. One approach that has gained popularity is the Local Interconnection Network (LIN). LIN has the specific goal of defining a low cost open networking standard for in-vehicle communication with an emphasis on data integrity, error recovery and fault protection
DC Motor Control in High Temperature Environment
The demand for driver solutions in “under-the-hood” environments is rapidly increasing, and in particular, the use of applications such as turbo chargers, EGR, or AGR calls for new solutions. This document explains Atmel®’s High Temperature H-bridge Motor Control System.
