The Motorola Scalable Controller Area Network (MSCAN) definition is based on the MSCAN12 definition which is the specific implementation of the Motorola Scalable CAN concept targeted for the Motorola MC68HC12 Microcontroller Family.

The module is a communication controller implementing the CAN 2.0 A/B protocol as defined in the BOSCH specification dated September 1991. For users to fully understand the MSCAN specification, it is recommended that the Bosch specification be read first to familiarize the reader with the terms and concepts contained within this document.

The CAN protocol was primarily, but not only, designed to be used as a vehicle serial data bus, meeting the specific requirements of this field: real-time processing, reliable operation in the EMI environment of a vehicle, cost-effectiveness and required bandwidth. MSCAN utilizes an advanced buffer arrangement resulting in a predictable real-time behavior and simplifies the application software.
