Atmel Releases New CAN Transceivers for the CAN FD Standard


Suitable for Data Rates up to 5Mbits/s and Fully Compliant with ISO Standards


Atmel have announced a new family of control area network (CAN) transceivers for the automotive and industrial markets. Supporting the new CAN FD (flexible data rate) standard with data rates up to 5Mbits/s, Atmel's new ATA6560 and ATA6561 provide an interface between a CAN protocol controller and the physical two-wire CAN bus.

Compliant with ISO11898-2, ISO11898-5 and SAEJ2284, the new CAN transceiver family offers high electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance. Both the ATA6560 and ATA6561 devices deliver ideal passive behavior to the CAN bus when the supply voltage is off, while the ATA6561 offers a direct interface to MCUs with 3V to 5V supply voltages. Various operating modes together with the dedicated fail-safe features make the ATA6560/ATA6561 an excellent choice for all types of high-speed CAN networks, especially in CAN nodes requiring a low-power mode with wake-up capability via the CAN bus. Atmel's new low-power CAN transceivers are developed on an advanced process technology that allows further integration of analog and complex digital functionality. The devices are available in SO8 and DFN8 packages with wet-able flanks for automated optical solder inspection.

“Our new family of CAN transceivers enables our OEMs to bring improved connectivity with higher speed in their automobile with overall lower power,” said Claus Mochel, marketing director for automotive high voltage products, Atmel Corporation. “We are continuing to expand our automotive product portfolio to give our customers the right mix of products to help shorten their design cycle and bring next-generation designs faster to market.”

Features of the Atmel's ATA6560/61 include:

  • Data rate up to 5Mbits/s
  • Fully ISO 11898-2,-5, SAE J2284 compliant
  • Low EME and high EMI
  • Remote wake-up capability via CAN bus
  • Transmit data (TXD) dominant time-out function
  • Undervoltage detection on VCC and VIO pins
  • CANH/CANL short-circuit and over temperature protected
  • ATA6560: Silent Mode (Receive only)
  • ATA6561: Compatible to 3.3V and 5V control signals
