Functional Description The Atmel® ATA6560/ATA6561 is a stand-alone high-speed CAN transceiver compliant with the ISO 11898-2 and 11898-5 CAN standard. 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: ● Atmel ATA6561: The 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. ● 2.1 Atmel ATA6560: The pin 5 is the control input for silent mode NSIL allowing the ATA6560 to only receive data but 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. Operating Modes The Atmel ATA6561 supports three operating modes: unpowered, standby and normal. The Atmel ATA6560 additionally has the silent mode. These modes can be selected via the STBY and NSIL pins. See Figure 2-1 and Table 2-1 for a description of the operating modes. Figure 2-1. Operating Modes ATA6560 VCC < Vuvd(VCC) ATA6561 VCC < Vuvd(VCC) or VIO < Vuvd(VIO) VCC < Vuvd(VCC) Unpowered Mode VCC < Vuvd(VCC) or VIO < Vuvd(VIO) VCC > Vuvd(VCC) VCC < Vuvd(VCC) STBY = 1 STBY = 1 Standby Mode STBY = 0 and (NSIL = 0 or TXD = 0) Unpowered Mode VCC > Vuvd(VCC) and VIO > Vuvd(VIO) STBY = 1 STBY = 1 STBY = 0 and TXD = 0 STBY = 0 and NSIL = 1 and Standby Mode STBY = 0 and TXD = 1 and Error = 0 TXD = 1 and Error = 0 NSIL = 1 and TXD = 1 and Error = 0 Silent Mode VCC < Vuvd(VCC) or VIO < Vuvd(VIO) * Normal Mode Error = 0 and TXD = 1 Silent Mode Normal Mode Error = 1 NSIL = 0 or Error = 1 * Silent Mode is externally not accessible Note: For the Atmel ATA6561 NSIL is internally set to “1”.

Reflects the bus only for wake-up ATA6560/ATA6561 [DATASHEET] 9288J–AUTO–04/15 2.1.1 Normal Mode A low level on the STBY pin together with a high level on pins TXD and NSIL selects the normal mode. In this mode the transceiver is able to transmit and receive data via the CANH and CANL bus lines (see Figure 1 on page 2). 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 VCC/2 and the undervoltage monitoring of VCC is active. The slope of the output signals on the bus lines is controlled and optimized in a way that guarantees the lowest possible electromagnetic emission (EME). To switch the device in normal operating mode, set the STBY pin to low and the TXD pin and the NSIL pin (if applicable) to high (see Table 2-1 on page 4, Figure 2-2 and Figure 2-3). The STBY and the NSIL pins each provide a pull-up resistor to VIO, thus ensuring defined levels if the pins are open. Please note that the device cannot enter Normal Mode as long as TXD is at ground level. Atmel® ATA6560 will only switch to normal mode when all inputs are set accordingly. The switching into normal mode is depicted in the following two figures. Figure 2-2.

Switching from Silent Mode to Normal Mode STBY t NSIL t TXD t tdel(sil-norm) = 10µs max Operation Mode Silent Mode Normal Mode t ATA6560/ATA6561 [DATASHEET] 9288J–AUTO–04/15 5 2.1.2 Silent Mode (Only with the Atmel ATA6560) A low level on the NSIL pin (available on pin 5) and on the STBY pin selects silent mode. This receive-only mode can be used to test the connection of the bus medium. In silent mode the Atmel ATA6560 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 comparator (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. 2.1.3 Standby Mode A high level on the STBY pin selects standby mode. In this mode the transceiver is not able to transmit or correctly receive data via the bus lines. The transmitter and the high-speed comparator (HSC) are switched off to reduce current consumption and only the low- power wake-up comparator (WUC) monitors the bus lines for a valid wake-up signal. A signal change on the bus from “Recessive” to “Dominant” followed by a dominant state longer than twake switches the RXD pin to low to signal a wake-up request to the microcontroller. In standby mode the bus lines are biased to ground to reduce current consumption to a minimum. The wake-up comparator (WUC) monitors the bus lines for a valid wake-up signal. When the RXD pin switches to low to signal a wake-up request, a transition to normal mode is not triggered until the STBY pin is forced back to low by the microcontroller. A bus dominant time-out timer prevents the device from generating a permanent wake-up request by switching the RXD pin to high. For Atmel® ATA6560 only: In the event the NSIL input pin is set to low in standby mode, the internal pull-up resistor causes an additional quiescent current from VIO to GND. Atmel therefore recommends setting the NSIL pin to high in standby mode. 2.2 Fail-safe Features 2.2.1 TXD Dominant Time-Out Function A TXD dominant time-out timer is started when the TXD pin is set to LOW. If the LOW state on the TXD pin persists for longer than tto(dom)TXD, the transmitter is disabled, releasing the bus lines to recessive state. This function prevents a hardware and/or software application failure from driving the bus lines to a permanent dominant state (blocking all network communications). The TXD dominant time-out timer is reset when the TXD pin is set to HIGH (≥ 4µs). 2.2.2 Internal Pull-Up Structure at the TXD, NSIL, and STBY Input Pins The TXD, STBY, and NSIL pins have an internal pull-up to VIO. This ensures a safe, defined state in case one or all of these pins are left floating. Pull-up currents flow in these pins in all states, meaning all pins should be in high state during standby mode to minimize the current consumption. 2.2.3 Undervoltage Detection on Pins VCC and VIO If VVCC or VVIO drop below their respective undervoltage detection levels (Vuvd(VCC) and Vuvd(VIO) (see Section 6. “Electrical Characteristics” on page 9), the transceiver switches off and disengages from the bus until VVCC and VVIO have recovered. The low-power wake-up comparator is only switched off during a VCC or VIO undervoltage. The logic state of the STBY pin is ignored until the VCC voltage or the VIO voltage has recovered. 2.2.4 Bus Wake-up Time-out Function In standby mode a bus wake-up time-out timer is started when the CAN bus changes from recessive to dominant state. If the dominant state on the bus persists for longer than tto_bus, the RXD pin is switched to HIGH. this function prevents a clamped dominant bus (due to a bus short-circuit or a failure in one of the other nodes on the network) from generating a permanent wake-up request. The bus wake-up time-out timer is reset when the CAN bus changes from dominant to recessive state. 2.2.5 Overtemperature Protection The output drivers are protected against overtemperature conditions. If the junction temperature exceeds the shutdown junction temperature, TJsd, the output drivers are disabled until the junction temperature drops below TJsd and pin TXD is at high level again. The TXD condition ensures that output driver oscillations due to temperature drift are avoided. 6 ATA6560/ATA6561 [DATASHEET] 9288J–AUTO–04/15 Figure 2-4. Release of Transmission after Overtemperature Condition Failure Overtemp OT Overtemperature t TXD VIO GND t BUS VDIFF (CANH-CANL) D R D R D R tt RXD VIO GND t 2.2.6 Short-Circuit Protection of the Bus Pins The CANH and CANL bus outputs are short-circuit protected, either against GND or a positive supply voltage. A currentlimiting circuit protects the transceiver against damage. If the device is heating up due to a continuous short on CANH or CANL, the internal overtemperature protection switches the bus transmitter off. 2.2.7 RXD Recessive Clamping This fail-safe feature prevents the controller from sending data on the bus if it’s RXD line is clamped to HIGH (e.g., recessive). That is, if the RXD pin cannot signalize a dominant bus condition because it is e.g, shorted to VCC, the transmitter within ATA6560/ATA6561 is disabled to avoid possible data collisions on the bus. In normal and silent mode (only ATA6560), the device permanently compares the state of the high-speed comparator (HSC) with the state of the RXD pin. If the HSC indicates a dominant bus state for more than tRC_det without the RXD pin doing the same, a recessive clamping situation is detected and the device is forced into silent mode. This fail-safe mode is released by either entering standby or unpowered mode or if the RXD pin is showing a dominant (e.g., LOW) level again. Figure 2-5. RXD Recessive Clamping Detection CAN TXD RXD Operation Mode Normal Silent Normal If the clamping condition is removed and a dominant bus is detected, the transceiver goes back to normal mode.
