ATA6560/1

• ATA6561: Pin 5 is the VIO pin and should be

connected to the microcontroller supply voltage.

This allows direct interfacing to microcontrollers

with supply voltages down to 3V and adjusts the

signal levels of the TXD, RXD, and STBY pins to

the I/O levels of the microcontroller. The I/O ports

are supplied by the VIO pin.

FUNCTIONAL DESCRIPTION

The ATA6560/1 is a stand-alone, high-speed CAN

transceiver, compliant with the ISO 11898-2 and

ISO 11898-5 standards. It provides a very low current

consumption in Standby mode and wake-up capability

via the CAN bus. There are two versions available, only

differing in the function of pin 5:

• ATA6560: Pin 5 is the control input for Silent mode

NSIL, allowing the ATA6560 to only receive data

and not send data via the bus. The output driver

stage is disabled. The VIO line and the VCC line

are internally connected; this sets the signal levels

of the TXD, RXD, STBY, and NSIL pins to levels

compatible with 5V microcontrollers.

1.1

Operating Modes

The ATA6561 supports three operating modes: Unpow-

ered, Standby, and Normal. The ATA6560 has an addi-

tional Silent mode. These modes can be selected via

the STBY and NSIL pin. See Figure 1-1 and Table 1-1

for a description of the operating modes.
