Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix '-N' corresponds to the specific package variant required, as it indicates the inclusion of wettable flanks for improved solder joint inspection. Confirm that the VDFN8 package with the exposed thermal pad is correctly integrated into the PCB layout to ensure proper grounding and thermal dissipation. Ensure all design parameters align with the official datasheet specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the ATA6561-GBQW-N when the application requires a VIO pin to interface directly with 3.3V or 5V microcontrollers, distinguishing it from the ATA6560 which lacks this feature. Choose this model if the design necessitates the VDFN8 package with wettable flanks for enhanced reliability during automated optical inspection. Ensure the system requirements match the 5 Mbps speed limit and the specified operating temperature range for optimal performance.

Drivers, Receivers, Transceivers Part Context

The ATA6561-GBQW-N belongs to the ATA6560/1 family of high-speed CAN transceivers produced by Microchip Technology. This family is engineered to provide reliable communication between controller area network protocol controllers and the physical two-wire bus. The ATA6561 variant specifically includes a VIO pin for flexible I/O level adaptation, making it suitable for modern microcontroller architectures.

Drivers, Receivers, Transceivers Replacement Considerations

The ATA6561-GBQW is the non-'N' equivalent within the same family, differing primarily in package characteristics. Both variants share identical electrical functionality and pinouts. Verify that the replacement part meets the specific packaging requirements of the assembly process, particularly regarding the presence or absence of wettable flanks.

Drivers, Receivers, Transceivers FAQ

What is the function of the VIO pin on the ATA6561?

The VIO pin serves as the supply voltage for the I/O level adapter, allowing the transceiver to interface directly with microcontrollers having supply voltages ranging from 2.8V to 5.5V.

How does the device behave when unpowered?

In the Unpowered Mode, the transceiver disengages from the bus, presenting a recessive state on both the CANH and CANL lines to prevent interference with other nodes.

What fail-safe features are included in the ATA6561?

The device includes TXD dominant time-out, undervoltage detection on VCC and VIO pins, overtemperature protection, short-circuit protection for bus pins, and RXD recessive clamping detection.
