CAN Flexible Data-rate and CAN Partial Networking transceiver family includes automotive parts

The industry’s family of Controller Area Network (CAN) transceivers including various automotive Grade 0 qualified parts is now available from Microchip Technology Inc. The ATA65XX family adds six new devices to Microchip’s CAN portfolio.

The new family supports the recently established CAN FD (Flexible Data-rate) protocol for up to five Mbit/s communication speed and the new CAN PN (Partial Networking) standard for improved energy efficiency of vehicles. Therefore, the devices are fully compliant with the ISO 118980-2/5/6, 11898-2:2016 and the SAE J2962-2 standards. The ATA6562, ATA6563, ATA6564, ATA6565 and ATA6566 build the industry’s first automotive Grade 0 qualified CAN/CAN FD transceiver family with an ambient temperature rating of -40° to 150°C.

The family also provides a CAN partial networking transceiver including a window watchdog. All devices in the family are approved by major car manufacturers for use without the external Common Mode Choke (CMC) that is required for most CAN transceivers.

“Microchip has one of the strongest and most complete CAN portfolios in the industry,” said Matthias Kaestner, vice president of Microchip’s automotive division. “Our transceivers ensure reliable communication in the harsh automotive environment with less external components and minimal board space which leads to lower system cost.”

All family members include wake-up capability via CAN bus with dual wake up pattern according to ISO11898-2:2016. A modern vehicle contains more than 70 Electronic Control Units (ECU) with CAN interface. This feature avoids unwanted power-up sequences, leading to significant energy savings and reduced emissions.
