AtmelВ® ATA6614Q 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 ATA6630, which has an integrated LIN transceiver, a 5V regulator
(85mA) and a window watchdog. The second chip is an automotive microcontroller from Atmel’s series of AVR® 8-bit
microcontroller with advanced RISC architecture and 32Kbytes of flash (Atmel ATmega328P). All pins of the AVR
microcontroller and almost all pins of the LIN System Basis Chip are bonded out to provide customers the same flexibility for
their applications as they have when using discrete parts.
The Atmel ATA6614Q is pin compatible to the Atmel ATA6612P/ATA6613P.
In Section 2. “Pin Configuration” on page 3 you will find the pin configuration for the complete SiP. In Section 3. “Absolute
Maximum Ratings” on page 5 to Section 5. “Microcontroller Block” on page 30 the LIN SBC is described, and in Section 7.
“Ordering Information” on page 307 the AVR is described in detail. …
