ATA6564

The slope of the output signals on the bus lines is con-

trolled and optimized in a way that ensures the lowest

possible electromagnetic emission (EME).

1.0

FUNCTIONAL DESCRIPTION

The ATA6564 is a stand-alone high-speed CAN

transceiver compliant with the ISO 11898-2, ISO

11898-2: 2016 and SAE J2962-2 CAN standards. It

provides very low current consumption in Silent mode.

To switch the device in normal operating mode, set the

S pin to low and the TXD pin to high. See Table 1-1 and

Figure 1-2. The S pin provides a pull-down resistor to

GND, thus ensuring a defined level if the pin is open.

1.1

Operating Modes

Please note that the device cannot enter Normal mode

as long as TXD is at ground level.

The ATA6564 supports two operating modes: Silent

and Normal. These modes can be selected via the S

pin. See Figure 1-1 and Table 1-1 for a description of

the operating modes.

1.1.2

SILENT MODE

A high level on the S pin selects Silent mode. This

receive-only mode can be used to test the connection

of the bus medium. In Silent mode the ATA6564 can

still receive data from the bus, but the transmitter is

disabled and therefore no data can be sent to the CAN

bus. The bus pins are released to recessive state. All

other IC functions, including the high-speed compara-

tor (HSC), continue to operate as they do in Normal

mode. Silent mode can be used to prevent a faulty CAN

controller from disrupting all network communications.

1.1.1

NORMAL MODE

A low level on the S pin together with a high level on pin

TXD selects the Normal mode. In this mode, the trans-

ceiver is able to transmit and receive data via the

CANH and CANL bus lines (see Section “Functional

Block Diagram”). The output driver stage is active and

drives data from the TXD input to the CAN bus. The

High-Speed Comparator (HSC) converts the analog

data on the bus lines into digital data which is output to

pin RXD. The bus biasing is set to V_VCC/2 and the

undervoltage monitoring of VCC is active.
