ATA6562/3
High-Speed CAN Transceiver with Standby Mode
Features
General Description
• Fully ISO 11898-2, ISO 11898-2: 2016 and
SAE J2962-2 Compliant
The ATA6562/3 is a high-speed CAN transceiver that
provides an interface between a Controller Area Net-
work (CAN) protocol controller and the physical
Two-Wire CAN bus. The transceiver is designed for
high-speed (up to 5 Mbps) CAN applications in the
automotive industry, providing differential transmit and
receive capability to (a microcontroller with) a CAN pro-
tocol controller.
• CAN FD Ready
• Communication Speed up to 5 Mbps
• ISO 26262 Functional Safety Ready
• Low Electromagnetic Emission (EME) and High
Electromagnetic Immunity (EMI)
• Differential Receiver with Wide Common-Mode
Range
It offers improved electromagnetic compatibility (EMC)
and ESD performance as well as features such as:
• ATA6562: Silent Mode
• Ideal passive behavior to the CAN bus when the
supply voltage is off
• 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
• Direct interfacing to microcontrollers with supply
voltages from 3V to 5V (ATA6563)
• Functional Behavior Predictable under All Supply
Conditions
Three operating modes together with the dedicated
fail-safe features make the ATA6562/3 an excellent
choice for all types of high-speed CAN networks, espe-
cially in nodes requiring Low-Power mode with
wake-up capability via the CAN bus.
• Transceiver Disengages from the Bus When Not
Powered Up
• RXD Recessive Clamping Detection
• High Electrostatic Discharge (ESD) Handling
Capability on the Bus Pins
Package Types
• Bus Pins Protected Against Transients in
Automotive Environments
