ATA6565
Dual High-Speed CAN Transceiver with Standby Mode
Features
General Description
• Fully ISO 11898-2, ISO 11898-5,
ISO 11898-2:2016, and SAE J2962-2 Compliant
The ATA6565 is a fully integrated, dual high-speed
Controller Area Network (CAN) transceiver with two
completely independent and separated high-speed
CAN transceivers integrated in one package (only the
GND pins, GND1 and GND2, are internally connected).
Each of the two identical transceivers provides an inter-
face between a CAN protocol controller and a physical
two-wire CAN bus.
• CAN FD Ready
• Communication Speed Up to 5 Mbps
• Low Electromagnetic Emission (EME) and High
Electromagnetic Immunity (EMI)
• Differential Receiver with Wide Common-Mode
Range
The device is designed for high-speed (up to 5 Mbps)
CAN applications in the automotive industry, providing
differential transmit and receive capability to (a micro-
controller with) a CAN protocol controller. It offers
improved Electromagnetic Compatibility (EMC) and
Electrostatic Discharge (ESD) performance, as well as
features such as:
• Remote Wake-up Capability via CAN Bus –
Wake-up on Pattern (WUP) as Specified in
ISO 11898-2:2016, 3.8 µs Activity Filter Time
• Functional Behavior Predictable Under All Supply
Conditions
• Transceiver Disengages from the Bus when Not
Powered Up
• Ideal passive behavior to the CAN bus when the
supply voltage is off
• RXD Recessive Clamping Detection
• High Electrostatic Discharge (ESD) Handling
Capability on the Bus Pins
• Very low current consumption in Standby mode
with bus wake-up capability
• Bus Pins Protected Against Transients in
Automotive Environments
Two operating modes, together with the dedicated
fail-safe features, make the ATA6565 an excellent choice
for all types of high-speed CAN networks. The ATA6565
includes more than one high-speed CAN interface, which
requires a Low-Power mode with wake-up capability via
the CAN bus. These features are especially valuable for
body control units and gateways.
• Transmit Data (TXD) Dominant Time-out Function
• Undervoltage Detection on VCC Pin
• Bus Pins Short-Circuit and Overtemperature
Protected
• Fulfills the OEM “Hardware Requirements for LIN,
CAN and FlexRay™ Interfaces in Automotive
Applications”, Rev. 1.3
Package Types
• Qualified According to AEC-Q100 and AEC-Q006
