CAN transceivers address EMC compatibility requirements

The devices convert digital protocol information into analog CAN communication across in-vehicle networks, as well as long-length CAN node interconnect for industrial applications. Both products offer outstanding performance at 2Mbps baud rate to address CAN flexible data application requirements. The low emission design combined with high immunity enables optimum EMC performance, whilst the 5V and 3.3V I/O compatibility includes an auto-detect. The devices are available with industry-specific product options: for automotive applications there is a built-in “Tx Dominant Timeout” feature (MC33901), and for industrial applications there is built-in support for long-length and low baud rate networks (MC34901). The devices are also pin-for-pin compatible with the industry standard.

“Last month, Freescale announced a major initiative to expand our analog portfolio to address the growing industrial market, and today’s introduction of these world-class CAN devices underscores the focus and speed with which we are executing to our strategic industrial analog initiative,” said James Bates, senior vice president and general manager for Freescale’s Analog and Sensors business. “Our newest high-speed CAN devices are a perfect example of how Freescale is aggressively leveraging our automotive expertise in safety, efficiency and robustness for the fast-growing industrial space.”

The MC33901 and MC34901 devices are planned for availability in Q2 2014. To help accelerate time-to-market and demonstrate the benefits of the multiple embedded functions of the devices, Freescale offers industrial and automotive market-specific feature sets, a small form factor evaluation board, as well as OEM certification reports from external laboratories to facilitate design selection.
