ATA6563-GAQW1 Descripción general
A CAN FD transceiver (Controller Area Network with Flexible Data-Rate) is the physical-layer device that translates the differential logic signals of a CAN protocol controller into the bus-side differential signaling required by the ISO 11898-1 standard. CAN transceivers belong to the broader category of automotive-grade communication interface ICs, sitting in the signal chain between a microcontroller's CAN controller and the actual bus wiring. CAN FD extends classical CAN from 1 Mbit/s to 5 Mbit/s by allowing faster bit rates during the data phase, and the transceiver must preserve the dominant-bit timing needed for arbitration.
Key features include compliance with ISO 11898-1:2015, low electromagnetic emission (EME), high electromagnetic immunity (EMI), an under-voltage detection on VCC and VIO, thermal shutdown protection, and bus-pin transient voltage robustness typical of automotive transceivers. The -GAQW1 ordering code designates the SOIC-8 variant (3.9 mm body width, tape-and-reel packaging, automotive qualification per AEC-Q100).
The architecture combines a differential transmitter with slope-controlled output to limit EME, a high-CMRR differential receiver, and integrated protection diodes on the bus pins. The VIO reference pin lets the logic interface track I/O voltages down to 1.8V on modern microcontrollers, while the WUP function filters remote-frame wake-up events per the ISO 11898-2 standard. Bus pins are tolerant to -27V to +40V and include load-dump resilience typical of automotive CAN transceivers.
Typical applications include automotive body and powertrain ECUs, ADAS sensor nodes, industrial CAN FD networks, gateway modules bridging CAN and CAN FD segments, and battery-management or motor-control ECUs that need a low-power standby mode with selective wake-up. Industrial uses include CANopen and DeviceNet nodes and remote I/O blocks. When designing with the ATA6563-GAQW1, place a 100 nF decoupling capacitor close to VCC and use a split termination (60 ohm resistor + 4.7 nF capacitor) on each bus terminal to meet OEM EMC requirements.

Aplicaciones típicas
ATA6563-GAQW1 es adecuado para 6 aplicacións: Automotive Body Control Module (BCM), ADAS Sensor Node (Radar / Lidar), Electric Vehicle Battery Management System (BMS), Industrial CANopen / DeviceNet Node, Automotive Gateway ECU, Motor Control ECU (BLDC / PMSM).
Automotive Body Control Module (BCM)
The ATA6563-GAQW1's AEC-Q100 Grade 0 qualification (-40C to +150C) and 5 Mbit/s CAN FD support make it ideal for body control modules that aggregate door, lighting, and HVAC nodes over a CAN FD backbone. Its VIO pin interfaces directly to 3.3V microcontrollers, eliminating external level shifters. The integrated Wake-Up Pattern (WUP) receiver allows the BCM to enter low-power standby while still monitoring the bus for remote wake-up frames from other ECUs, supporting OEM parasitic-drain targets under 100 uA.
Recomendado
ADAS Sensor Node (Radar / Lidar)
In advanced driver-assistance systems (ADAS), radar and lidar sensor ECUs use the ATA6563-GAQW1 to communicate object-detection data over CAN FD at 5 Mbit/s. The transceiver's high electromagnetic immunity (EMI) and low electromagnetic emission (EME) meet the stringent OEM EMC requirements for sensor zones, while the bus-pin transient tolerance (-27V to +40V) protects against load-dump events in the 12V automotive supply. The integrated thermal shutdown prevents damage under sustained fault conditions.
Recomendado
Electric Vehicle Battery Management System (BMS)
Battery management systems in electric vehicles require reliable CAN FD communication between battery modules and the vehicle's master ECU. The ATA6563-GAQW1's VIO logic-level shifting allows direct connection to low-voltage battery monitor MCUs, while its WUP standby mode supports ISO 11898-2 selective wake-up, addressing energy efficiency requirements in 400V/800V battery architectures where quiescent drain is critical. The -GAQW1's automotive Grade 0 rating ensures reliable operation across battery-pack temperature extremes.
Recomendado
Industrial CANopen / DeviceNet Node
In industrial automation, the ATA6563-GAQW1 is used in CANopen and DeviceNet slave nodes that communicate with PLCs and motor drives. Its 5 Mbit/s CAN FD capability allows higher process-data throughput than classical CAN, while the AEC-Q100 qualification ensures long-term availability and quality. Industrial designers benefit from the wide supply voltage tolerance (4.5V to 5.5V) and the bus-pin transient protection typical of automotive-grade CAN transceivers, providing robustness in electrically noisy factory environments.
Recomendado
Automotive Gateway ECU
Central gateway ECUs in modern vehicles bridge CAN, CAN FD, and Ethernet domains. The ATA6563-GAQW1's CAN FD support at 5 Mbit/s and VIO logic-level shifting allow the gateway MCU to terminate CAN FD segments without level translation. The Wake-Up Pattern receiver enables the gateway to selectively wake downstream sub-networks when traffic is detected, supporting partial-networking architectures demanded by next-generation vehicle EE systems. The transceiver's low standby current extends the duty cycle.
Recomendado
Motor Control ECU (BLDC / PMSM)
Brushless DC and permanent-magnet synchronous motor controllers in automotive and industrial applications use the ATA6563-GAQW1 to report torque, speed, and fault data to a central ECU. The transceiver's high electromagnetic immunity (EMI) is critical near the motor inverter's switching noise, while its 5 Mbit/s CAN FD support enables real-time torque-vectoring and upper-speed telemetry for high-bandwidth control loops. The thermal shutdown protection guards against fault conditions during stall events.

Notas de diseño
Place a 100 nF X7R ceramic decoupling capacitor as close as possible to the VCC pin (pin 3) and another 100 nF X7R near the VIO pin (pin 5). Keep the VCC and VIO traces short and wide to minimize parasitic inductance. The CANH/CANL traces should be routed as a differential pair with 100-ohm characteristic impedance, kept as short as practical, and routed away from switching nodes to preserve signal integrity.
Use a split termination scheme on each end of the CAN bus: a 60-ohm resistor from CANH to CANL in series with a 4.7 nF (or 100 nF) capacitor to ground. This split termination reduces common-mode emissions at high data rates and meets OEM automotive EMC requirements such as IEC 62228-3. Avoid stubs on the CAN bus - keep drop lengths below 1/10 of the signal rise time for the chosen bit rate (under 100 mm at 5 Mbit/s).
Do not connect VIO to a supply that is enabled after VCC at startup, or the TXD/RXD logic levels will be undefined during MCU boot. Tie STBY (pin 8) high via a 10 kohm pull-up to VIO for normal operation, or low via the MCU GPIO for standby entry. Avoid leaving STBY floating - undefined logic on STBY can cause the transceiver to enter an unknown mode and miss CAN frames. Also ensure the CAN bus is biased recessive before exiting standby to avoid spurious transmission.
The VCC and VIO rails must be sequenced correctly: VIO should ramp before or simultaneously with VCC. According to the Microchip datasheet, an under-voltage condition on VCC or VIO forces the transceiver into a defined state. Add bulk capacitance (10 uF to 47 uF) near the transceiver if the upstream 5V regulator is shared with other loads. The quiescent current draw in standby is in the low-microampere range and must be considered when designing battery-parasitic budgets.
