Atmel Extends Automotive Leadership, Launches Fourth Generation Low-Power LIN System Basis Chip (SBC) for In-vehicle Networking

- Offering the Industry’s Largest LIN Portfolio, New LIN SBC Devices Deliver Lower Power Consumption, Improved LDO works down to 2.3V, MLC Blocking Capacitors for Lower Overall System Cost - Industry’s First Device that Complies with the New OEM Hardware Recommendations

San Jose, CA, February 19, 2014 - Atmel® Corporation (NASDAQ: ATML), a leader in microcontroller and touch technology solutions, today announced a new LIN system basis chip (SBC) ATA663254 for low-power local interconnect networking (LIN) systems used for automotive comfort, power-train, sensor and actuator applications. Atmel’s ATA663254 is the first available device in this family of new LIN devices.

Atmel's new generation of LIN SBC devices delivers significantly lower current consumption in various modes of operation. The integrated low dropout voltage regulator (LDO) can be used in combination with low-cost  MLC (multi-layer ceramic) blocking capacitors providing significant cost savings compared to solutions using tantalum capacitors. The improved voltage regulator works down to 2.3V supply voltage with best-in-class current consumption. This enables storing data within the MCU during system shutdown in case of unintended power supply interruption. The advanced features of the ATA663254 enable system designers to design best-in-class in-vehicle network applications in the latest automobiles. The devices are LIN specification 2.0, 2.1, 2.2, 2.2A and SAE J2602-2 certified.

Atmel’s new cost-optimized and performance enhanced LIN SBC is developed on a proprietary BCD-on-SOI (Bipolar CMOS and DMOS-on-Silicon on Insulator) process technology that combines high-voltage capability with rugged silicon on insulator technology. This combination allows for high-temperature operation, excellent EMC performance and very low leakage currents.

"As the leading automotive LIN provider with the largest LIN product portfolio worldwide, we are committed to delivering the most advanced solutions to meet customer and market demands for designing the latest in-vehicle networking systems," said Rob Valiton, Senior Vice President and General Manager, Automotive, Aerospace and Memory Business Units. "Adding to our diverse automotive product portfolio, this new LIN SBC device addresses the latest requirements for in-vehicle networking systems including lower power consumption, more compact PCB board designs and enabling an overall lower system cost. As the automotive design cycle continues to shorten, Atmel is committed to delivering the most innovative automotive products that enable customers to bring their unique, next-generation designs quickly to market."
