Atmel Corp. has announced the availability of the ATA6602 and ATA6603 multichip modules, extending Atmel's current broad IC family for LIN applications. These devices are designed for automotive actuator applications typically found in comfort electronics (e.g., window lifter, mirror or seat adjuster) as well as in powertrain applications. The ATA6602 and ATA6603 are also for sensor node applications such as control panels, air quality, rain/sun sensors and many more.
These two ICs combine a microcontroller (8-bit AVR) and a LIN system basis chip (LIN SBC) in a single package (SiP, system-in-package) without internal connections. As a result, the ATA6602/ATA6603 ICs offer the highest integration level including microcontroller, voltage regulator, LIN transceiver and watchdog in one package covering the complete basic functionality of a LIN node. These products achieve minimum space requirements, shorter time-to-market due to the simpler system design, and lower sourcing, logistics, and assembly cost.
The ATA6602 integrates the automotive-qualified ATmega88 AVR Flash MCU with 8 KB of Flash memory, whereas the ATA6603 incorporates the automotive-qualified ATmega168 with a Flash memory of 16 KB. The LIN SBCs within the ATA6602 and ATA6603 modules incorporate the LIN transceiver, an advanced voltage regulator, and a watchdog timer. They are manufactured using Atmel's high-voltage BCDMOS process for operation in harsh environments. Thanks to its silent mode, the LIN SBC provides very low power consumption (40 microamps with activated voltage regulator). In addition, the LIN SBC provides high immunity against ESD and EMC, various protection functions, and a unique, broad input/output voltage range (-40 to 60V) for the LIN bus pin which is for use in truck applications. Samples of the ATA6602/ATA6603 in QFN48 (7 x 7 mm) packages are available now. Pricing starts at US$1.87 (ATA6602) for 10k pieces and US$1.99 (ATA6603) for 10k pieces.
