| Description | The ATA6561-GAQW-N is a high-speed CAN and CAN FD transceiver from Microchip Technology, designed to provide the physical interface between a CAN protocol controller and the two-wire CAN bus. The device combines high-speed communication, low-power standby operation, a dedicated VIO interface supply, excellent electromagnetic compatibility, and robust bus protection for demanding industrial and embedded communication systems. The ATA6561-GAQW-N supports high-speed CAN communication with data rates of up to 5Mbps, making it suitable for both classical CAN networks and applications using CAN Flexible Data Rate (CAN FD). Its optimized transmitter and receiver architecture provides reliable differential communication while supporting the higher data-phase speeds required by modern CAN FD networks. The device contains one CAN transmitter and one CAN receiver and operates as a half-duplex physical-layer transceiver. The TXD input accepts digital transmit data from the CAN controller, while the RXD output delivers received bus information back to the host microcontroller or CAN controller. A key feature of the ATA6561 is its dedicated VIO supply pin. This allows the digital interface levels at TXD, RXD, and control pins to be matched to the I/O voltage of the connected microcontroller. The feature simplifies interfacing with modern low-voltage MCUs while the CAN transceiver itself operates from its normal 5V-class supply. The main transceiver supply operates from approximately 4.5V to 5.5V. The separate VIO architecture provides additional flexibility when designing mixed-voltage systems and can eliminate the requirement for external logic-level translation between the CAN transceiver and the host processor. The ATA6561-GAQW-N incorporates a low-power standby mode for applications where reduced current consumption is required while the CAN network is inactive. The device can detect activity on the CAN bus and provides remote wake-up capability, allowing the system controller to remain in a low-power state until network communication resumes. The differential receiver provides a wide common-mode operating range and approximately 120mV receiver hysteresis, supporting reliable signal detection in electrically noisy environments. These characteristics are particularly useful in systems with long wiring harnesses, ground offsets, switching loads, motors, relays, and other potential sources of electrical interference. The ATA6561 family is designed with strong EMC and ESD performance. Its CANH and CANL bus pins are protected against electrical disturbances and transient conditions encountered in demanding CAN networks, helping improve communication reliability and reduce the requirement for additional interface protection components. The device also provides predictable behavior during abnormal supply conditions. Protection and fail-safe functions help prevent unwanted bus disturbance during undervoltage, power-up, power-down, or other operating conditions where the host controller or transceiver supply may not be fully active. Thermal protection is integrated into the device to protect the CAN output stage against excessive junction temperature. Additional internal protection mechanisms help protect the transmitter against bus fault conditions, providing a robust interface for industrial control and distributed embedded communication systems. The ATA6561-GAQW-N is supplied in an 8-lead SOIC package with a body width of approximately 3.9mm. The device is supplied in tape-and-reel packaging with a standard full-reel quantity of 4000 pieces, making it suitable for automated high-volume SMT manufacturing. The device supports a junction temperature range of -40°C to +150°C, enabling use in demanding environments where extended temperature capability and reliable CAN communication are required. The ATA6561-GAQW-N is widely used in CAN FD communication nodes, industrial automation equipment, motor controllers, battery management systems, power conversion equipment, industrial gateways, PLC modules, embedded controllers, sensor networks, actuator controllers, robotics, agricultural equipment, transportation electronics, diagnostic equipment, energy management systems, and distributed control applications requiring a compact and robust high-speed CAN physical-layer interface. |
