Beschreibung

ATAK42001-V1 Development Kit for the ATA664151 Atmel ICATAN00599284E-AUTO-02/15The development kit for the Atmel® ATA664151 IC consists of the PC interface board (ATAB0004A-V2.0) and the Atmel ATA664151 application board (ATAB664xA-V2.0) attached together. The kit provides users with a quick start guide for prototyping and testing new LIN designs with the ATA664151 IC.The Atmel ATA664151 is a system basis chip with an eight-channel high-voltage switch interface with HV current sources, a LIN 2.1 and SAEJ2602-2-compliant LIN transceiver, a 5V low-drop voltage regulator with up to 80mA current capability and an adjustable window watchdog. This chip combination makes it possible to develop simple, inexpensive, yet powerful slave and master nodes for LIN bus systems. The Atmel ATA664151 is designed in particular for LIN switch applications and includes nearly the entire LIN node. The development board is designed to handle low data-rate communication in vehicles (such as in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20Kbaud. Sleep mode and active low-power mode guarantee minimal current consumption even if there is a floating bus line or short circuit on the LIN bus toGND.
