CM0902
Dual High-Speed CAN Physical Layer
Overview
Industrial Applications
The CM0902 devices with Dual high-speed CAN physical layer are Freescale’s standard
•Transportation
cost-effective products used to convert digital protocol information into analog CAN
Heavy vehicles
communication. They target CAN high-speed operation with two fully independent CAN
Agriculture machinery
interfaces in a 14-pin SOIC package.
Aviation systems
The CM0902 supports long-length CAN node interconnects for industrial applications and has
an option with a built-in transceiver dominant timeout feature for automotive applications.
Freescale’s robust CM0902 dual CAN high-speed physical layers offer extremely low quiescent
current while exceeding the most stringent EMC/ESD requirements without added circuitry.

Electric Vehicles
The CM0902 allows for the implementation of a cost-effective system. These parts minimize
•Backplanes
external circuitry and save system cost, including the elimination of common mode choke.
•Lift/elevators
It’s easy to get started with the KIT33CM0902EFEVB and KIT34CM0902EFEVB evaluation
• Factory automation
boards. These small evaluation boards can be used for quick application prototyping and
demonstration of the CM0902 products for fast design and short time to market.
