... Packages: SO8, DFN8 1. Description The Atmel ATA6663 is a fully integrated LIN transceiver complying with the LIN specification 2.0, 2.1 and SAEJ2602-2. The Atmel ATA6664 is an identical version, the only difference is that the TXD-dominant Time-out function is disabled so the device is able to send a static low signal to the LIN bus. It interfaces the LIN protocol handler and the physical layer ...

... After switching on V and INHIBIT is switched on. The supply current in sleep mode is typically 10µA. 3.3 Ground Pin (GND) The Atmel ATA6663/ATA6664 does not affect the LIN Bus in the case of a GND disconnec- tion able to handle a ground shift up to 11. 3.4 Bus Pin (LIN) A low-side driver with internal current limitation and thermal shutdown, and an internal pull-up resistor are implemented as specified by LIN2.x. The voltage range is from – ...

... Even if the voltage exceeds the pre-wake detection high (V LINH This means the LIN bus must be above the Pre-wake detection threshold V microseconds before a new LIN wake-up is possible. Atmel ATA6663/ATA6664 6 ) and a rising edge at pin LIN results in a remote wake-up request. The BUS LIN Wake-up Waveform Diagram ...

... The wake-up request flag (indicated at pin RXD) as well as the wake-up source flag (indicated at pin TXD) are reset immediately if the microcontroller sets pin EN to high (see page 6 Atmel ATA6663/ATA6664 8 ), results in a local wake-up request. According to ISO7637, the wake-up time ensures ) and the internal termination resistor is switched on. The local ...
