FUNCTIONAL DESCRIPTION

The ATA6565 is a stand-alone, dual high-speed

CAN transceiver, compliant with the ISO 11898-2,

ISO 11898-5, ISO 11898-2:2016, and SAE J2962-2

standards. Each of the two transceivers provides a very

low current consumption in Standby mode and

wake-up capability via the CAN bus.

1.1

Operating Modes

Each of the transceivers supports three operating

modes: Unpowered, Standby, and Normal. Addition-

ally, there is the internal Silent mode, which is not exter-

nally accessible. This mode is a Receive Only mode,

which means the CAN drivers are deactivated and only

data from the bus can be received.

The functions described in the following text apply to

each of the two identical high-speed CAN transceivers

integrated in the ATA6565. Therefore, if for example,

the CANH pin is stated, this applies to each of the two

transceivers, meaning CANH1 and CANH2. The two

transceivers are identical, and there is no internal

The operating modes can be selected via the STBY pins

(STBY1 and STBY2). See Figure 1-1 and Table 1-1 for

a description of the operating modes.

Silent mode is externally not accessible. In this mode, the transceiver can only receive data from the bus,

but the transmitter is disabled.
