Atmel's Solution for Automotive LIN Networking Applications

The new LIN SiP is based on Atmel’s second-generation LIN IP with excellent EMC and ESD performance. It is optimized for low-cost LIN slave applications and enables system cost reductions of up to 25%. A powerful LIN UART with integrated hardware routines simplifies protocol stack handling and limits the interrupt generation, thus reducing the microcontroller load and flash memory consumption. Simple assignment of an individual physical LIN node address, which is important in applications such as air-conditioning systems, can be realized by using an integrated 100 microampere current source.

One important criteria for LIN applications is low current consumption. To ensure that the LIN node's current consumption is well below 100 microampere in applications that are continuously connected to the battery, the ATA6617 provides several current saving modes where different functionalities are individually switched off or on, depending on the application requirements.

All pins of the LIN system basis chip and the microcontroller are bonded out, thus providing customers the same flexibility and performance for their applications as with discrete parts.

Thanks to the QFN38 package, measuring only 5 x 7 mm, designers can save more than 50% of PCB size compared to conventional solutions.
