MICROCHIP ATA6613C-PLQW-1

Atmel ATA6612C/ATA6613C is a system-in-package (SiP) product, which is particularly suited for complete LIN-bus slave-node applications. It consists of two ICs in one package supporting highly integrated solutions for in-vehicle LIN networks. The first chip is the LIN-system-basis-chip (LIN-SBC) Atmel ATA6624, which has an integrated LIN transceiver, a 5V regulator and a window watchdog. The second chip is an automotive microcontroller from Atmel series of Atmel AVR 8-bit microcontroller with advanced RISC architecture. The Atmel ATA6612C consists of the LIN-SBC Atmel ATA6624 and the Atmel ATmega88 with 8Kbytes flash. The Atmel ATA6613C consists of the LIN-SBC Atmel ATA6624 and the Atmel ATmega168 with 16Kbytes flash. All pins of the LIN system basis chip as well as all pins of the Atmel AVR microcontroller are bonded out to provide customers the same flexibility for their applications as they have when using discrete parts.

The LIN-SBC ATA6624 is a fully integrated LIN transceiver, which complies with the LIN 2.0, 2.1 and SAEJ2602-2 specifications. It has a low-drop voltage regulator for 5V/85mA output and a window watchdog. The voltage regulator is able to source up to 85mA, but the output current can be boosted by using an external NPN transistor. The LIN-SBC is designed to handle the low-speed data communication in vehicles, e.g., in convenience electronics. Improved slope control at the LIN-driver ensures secure data communication up to 20kBaud. Sleep mode and silent mode guarantee very low current consumption.
