          ATA6617 – EK Development Board V1.1

          The development board for the ATA6617 IC is designed to give designers a quick start with the ATA6617 IC and to enable prototyping and testing new LIN designs.

          The ATA6617 is a dual-chip System-in-Package (SIP) product, which is particularly suited for complete LIN bus slave and master node applications. It supports highly integrated solutions for in-vehicle LIN networks. The first chip is the LIN-system-basis-chip (LIN SBC) ATA6624, which has an integrated 5V voltage regulator, a window watchdog, and a fully integrated LIN transceiver, in compliance with the LIN specification 2.1. The second chip is an automotive microcontroller from ’s series of AVR 8-bit microcontrollers with advanced RISC architecture (ATtiny167 with 16K flash). All pins of both integrated chips are bonded out to provide customers the same flexibility for their applications as they have when using discrete parts.

          ATA6617–EK 開發(fā)板特性:

          All Necessary Components to Put the ATA6617 in to Operation Are Included

          Placeholders for Some Optional Components for Extended Functions Included

          All Pins Easily Accessible

          Easily Adaptable Watchdog Times by Replacing a Single Resistor

          Possibility to Activate an External NPN-transistor to Boost the Output Current of the Voltage Regulator (Jumper JP3)

          Possibility to Select between Master or Slave Operation (Mounting D2 and R1)

          Possibility to Mount an External Quartz to Handle Time-critical Applications (Not Necessary for LIN Communication)

          Push Button Included to Create a Local Wake-up after Entering Sleep or Silent Mode

          Ground Coulter Clip for Connecting Probes when Measuring with the Oscilloscope
