Atmel announced the availability of two new transceiver families for LIN automotive networking applications. Featuring the industry's lowest power wake-up management (the power consumption of competing solutions is up to 10 times higher), the new Atmel LIN families serve automotive body electronics applications such as door modules, seat control or intelligent sensors, and powertrain applications such as engine control systems. In addition, Atmel's ATA6663/64 transceivers are suited for other body electronic applications where low-speed data communication and low cost are important.

Atmel's ATA6663 and ATA6664 are stand-alone LIN bus transceiver ICs, while the ATA6628/29/30/31 LIN transceivers are system basis chips (SBCs). When compared to a stand-alone LIN transceiver, SBCs are more integrated to include a voltage regulator, a Watchdog Timer (WDT), and high precise voltage divider for supply voltage measurements. The devices' low-power management also enables mixed-supplied LIN bus systems and short circuit-to-ground at the LIN bus with a lower power consumption.

These new LIN devices are designed with Atmel's high-voltage BCD-on-SOI (SMART-I.S.(TM)) process and optimized for operations up to 40V for applications in harsh environments. Combined with the industry's leading EMC robustness (EMC test and conformance test LIN2.1, Europe, and SAE J2602-2, US), customers can benefit from lower bill of material as well as lower software costs. The excellent ESD protection (exceeding 6 kV) is beneficial for designing robust electronic units for the harsh automotive environment.
