This was the part you picked when a single-chip design needed both a fieldbus gateway and a local control loop.
80 MHz Cortex-M3 — what that means for protocol throughput
At 80 MHz the Cortex-M3 core can handle Ethernet, USB, and CAN traffic when the DMA engine moves packet data.
Obsolete — sourcing this part today
Texas Instruments ended production on the Stellaris line after the acquisition by TI, and no direct pin-compatible replacement was released.
Ethernet and USB OTG — what the connectivity set enables
The on-chip Ethernet MAC with integrated PHY and the USB OTG controller make this MCU a natural fit for an industrial gateway that bridges a CAN-based machine to a plant network, or for a programmable logic controller that serves a web interface over Ethernet. The USB OTG port can act as a host for a flash drive (firmware update logging) or as a device for configuration from a laptop. The 60 I/O pins leave room for parallel LCD interfaces or a bank of opto-isolated inputs alongside the network ports.
Package and temperature grade — board-level fit
The 100-LQFP (14x14 mm) is a common footprint for mid-density MCUs; the 0.5 mm pitch means a 4-layer board with via-in-pad is not required, but a solid ground plane under the package helps with Ethernet PHY noise.
