Atmel Corp. unveiled a new SiP solution for LIN automotive networking applications, the ATA6614. It is an extension of the existing Atmel LIN SiP family. It merges the LIN System Basis Chip (SBC) ATA6630 together with a LIN transceiver and 5V voltage regulator, as well as the Atmel ATmega328P with 32k Flash memory, in a single package. It comes in a compact 7x7mm QFN48 package.

The new LIN SiP is patterned after the Atmel third-generation LIN intellectual property. Atmel says it has significantly improved EMC and ESD performance that complies with the latest car manufacturer requirements. It is maximized for low-cost LIN slave applications and permits system cost reductions of up to 25 percent. Moreover, the LIN SiP is fully compatible with the Atmel flexible QTouch library solution to provide button, slider and wheel touch applications to be implemented with the same device which communicates these touches, using available LIN protocol stacks over the LIN network.

LIN Marketing Manager at Atmel Corporation, Dr. Stephan Hartmann, states that this device features a remarkably low power LIN wake-up management and advanced AVR microcontrollers that use Atmel picoPower technology. He explains that power consumption of competing solutions can be up to 10x higher than those of the new Atmel SiP family. He adds, "This family is also suitable for automotive body electronics applications such as door modules, seat control or intelligent sensors, and automotive touch applications."

Samples of the new LIN IC ATA6614 are now available. Pricing begins at US$1.89 for 10,000-unit quantities. Various cost-effective tools are likewise available to support designers with the development of LIN networks. Certified LIN 2.0 and 2.1 protocol stacks are also available from leading suppliers.
