Stellaris Family of ARM™ Cortex®-M3 microcontrollers featuring fully integrated Bosch CAN networking technology, the golden standard in short-haul industrial networks. Stellaris devices include up to 2 Bosch-licensed CAN controllers, each of which supports CAN protocol version 2.0 part A/B, bit rates up to 1Mb/s, and 32 message objects, each with own identifier mask. Each CAN also features maskable interrupt, disable for automatic retransmission mode for TTCAN, and a programmable loop-back mode for self test operation.
