Atmel® Corporation (NASDAQ: ATML) launched its next-generation family of local interconnect networking (LIN) transceivers, system basis chips (SBC) and voltage regulators for automotive body, powertrain, infotainment sensor, actuator, and other automotive applications.

The company also announced a new family of control area network (CAN) transceivers for automotive and industrial markets. Those devices support the new CAN FD (flexible data rate) standard with data rates up to 5Mbits/s.

OEM Hardware Recommendations

According to Atmel, its new LIN transceivers are the industry’s first to comply with new original equipment manufacturer (OEM) hardware recommendations and to provide scalable functionality to improve overall system cost.

The devices feature an LDO with outstanding minimum supply voltage of 2.3V combined with linear mode current of 130uA to support data storage even during an unexpected shut down. The devices are compliant with the latest standards including LIN 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2. Some members of the family also include application specific functions such as relay drivers, watchdog, high-side switches and wake up inputs to enable system designers to build innovative in-vehicle network applications in next-generation automobiles.

The LIN devices are available in DFN packages with heat-slug and wet-able flanks to support optical solder inspection. These next-generation devices also provide a family package footprint so that designers can upgrade their designs with various devices within the LIN SBC family.

“Our expanded LIN portfolio includes pin-outs that are the first to support the new OEM hardware recommendations enabling system designers to develop differentiated LIN systems in next-generation vehicles,”  said Claus Mochel, Atmel’s marketing director for automotive high voltage products. “Atmel’s LIN family footprint makes it easier to migrate upwards and devices in the family offer application-specific functionality for various LIN-connected applications such as window lifters, sun-roofs, trunk opener or seat controls.”

CAN FD Support

Atmel’s  new family of control area network (CAN) transceivers supporting the new CAN FD (flexible data rate) standard with data rates up to 5Mbits/s. Atmel’s new ATA6560 and ATA6561 provide an interface between a CAN protocol controller and the physical two-wire CAN bus.

Compliant with ISO11898-2, ISO11898-5 and SAEJ2284, the new CAN transceiver family offers high electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance. Both the ATA6560 and ATA6561 devices deliver ideal passive behavior to the CAN bus when the supply voltage is off, while the ATA6561 offers a direct interface to MCUs with 3V to 5V supply voltages.

Various operating modes together with the dedicated fail-safe features make the ATA6560/ATA6561 an excellent choice for all types of high-speed CAN networks, especially in CAN nodes requiring a low-power mode with wake-up capability via the CAN bus. Atmel’s new low-power CAN transceivers are developed on an advanced process technology that allows further integration of analog and complex digital functionality. The devices are available in SO8 and DFN8 packages with wet-able flanks for automated optical solder inspection.

“Our new family of CAN transceivers enables our OEMs to bring improved connectivity with higher speed in their automobile with overall lower power,” said Mochel. “We are continuing to expand our automotive product portfolio to give our customers the right mix of products to help shorten their design cycle and bring next-generation designs faster to market.”
