The Stellaris® family is the first to offer ARM® Cortex™-M3 microcontrollers with USB 2.0 Full Speed On-The-Go (OTG) capability or USB 2.0 Full Speed Host/Device integrated alongside Bosch CAN technology.

Controller Area Network:
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 3 Bosch-licensed CAN controllers (up to 2 in USB-enabled Stellaris microcontrollers), 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.

USB On-The-Go or Host/Device:
For Stellaris devices integrating the USB On-The-Go controller, the controller operates as a function controller for a full-speed or low-speed device in point-to-point communications with USB host, device, or OTG functions. For Stellaris devices integrating the USB Host/Device controller, the controller operates as a function controller for a full-speed or low-speed host or device in point-to-point or multipoint (hub) communications with USB functions. In both OTG and Host/Device instances, the USB controller complies with the USB 2.0 standard, which includes suspend and resume signaling. Three configurable endpoints (1-3) with a dynamic sizable FIFO support multiple packet queueing. DMA access to the FIFO allows minimal interference from system software.
