New CAN family supports the new FD and PN standards

Now available from Microchip and claimed to be the industry’s first family of CAN transceivers that includes various automotive Grade 0 qualified parts is the ATA65XX family that adds six new devices to their CAN portfolio. The new family supports the recently established CAN FD protocol for up to five Mbit/s communication speed and the new CAN PN 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 -40C to 150C. The family also provides a CAN PN transceiver including a window watchdog. All devices in the family are approved by major car manufacturers for use without the external 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 ECUs with CAN interface. This feature avoids unwanted power-up sequences, leading to significant energy savings and reduced emissions.
