ATMEL ATA6631-EK 开发板, ATA6631, LIN总线收发器, 集成电压稳压器
The is an LIN bus transceiver with integrated voltage regulator. The development board for the Atmel ATA6631 is designed to give users a quick start using these ICs and prototyping and testing new LIN designs. The ATA6631 is a fully integrated LIN transceiver in compliance with LIN specification 2.0, 2.1 and SAEJ2602-2 with a 5V/85mA low drop voltage regulator. The Atmel ATA6631 are the successor ICs of the Atmel ATA6623/ATA6625 featuring enhanced EMC performance, reduced current consumption in silent mode, extended TXD time-out time and improved wake-up behaviour, resulting in a very low sleep mode and silent mode current consumption even in the case of a floating bus or a short circuit between the bus line and GND. The ICs are 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.
