Atmel Releases ATA664151 and ATA664251 LIN SBC and Microcontroller

Sun, Nov 18th, 2012. In Automotive, Vehicle, Networking

Atmel has announced the release of ATA664151 and ATA664251, two new LIN (Local Interconnect Networking) devices specially designed for automotive applications, such as lighting control and switch scan.  ATA664151 is a LIN SBC (System Basis Chip) with many feature such as LIN Transceiver, 8-channel High Voltage Switch Interface, 16-bit SPI, Watchdog and 5V Regulator. The ATA664251 is a system-in-package solution with an ATA664151 (LIN SBC) subsystem integrated with an ATtiny167 microcontroller (8-bit AVR ).  To accelerate development time Atmel offer ATAK42001-V1 Evaluation Kit for ATA664151 and ATAK43001-V1 Evaluation Kit for ATA664251.
