High-speed CAN Transceiver Supports 5 Mbps Speeds


Microchip has announced a range of CAN transceivers including various automotive Grade 0 qualified devices. The new ATA65XX devices support the new CAN FD and CAN PN standards and provide high-temperature variants for the harsh automotive environment.

The new devices support 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 ATA65XX family includes six new devices being added to the Microchip’s CAN portfolio. The ATA6562, ATA6563, ATA6564, ATA6565 and ATA6566 are automotive Grade 0 qualified CAN/CAN FD transceivers with an ambient temperature rating of -40° to 150°C. There is also a CAN PN transceiver device including a window watchdog.

All devices are approved by major car manufacturers for use without the external Common Mode Choke (CMC) that is required for most CAN transceivers, the firm stated in the Press release.


“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 devices include wake-up capability via CAN bus with dual wake-up pattern according to ISO11898-2:2016. As 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, Microchip noted.

Power Modules Offer A Route To Smaller HEV Inverters

The ATA65XX family is supported by the ATA656X-EK development kit, ATAB6570A development kit and the ATA6563 click board, all of which are available today.

The devices come in SO 8/14 and DFN8/14 packages with wettable flanks, ready for automatic optical solder-joint inspection.
