The industry’s first 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 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 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 (ECUs) with CAN interface. This feature avoids unwanted power-up sequences, leading to significant energy savings and reduced emissions.

Does this part allow for violating CAN protocol rules and speeding or slowing payload values? When you try connecting to various vehicles this is what the auto makers do, You cannot just put a CAN interface on any vehicle and expect them to follow the rules, you will get dropouts unless you have their secrets and know how the timing is hindered or modified
