Stellaris Cortex-M3 with Ethernet and CAN — what it was built for
The 32 available I/O and internal oscillator reduce external component count in space-constrained designs.
Obsolete — sourcing reality for a discontinued Stellaris MCU
This part is no longer available through franchised distribution channels.
50 MHz Cortex-M3 — what the speed and memory mean for a replacement search
The 50 MHz core speed places this MCU in the mid-range of Cortex-M3 devices — adequate for real-time control loops, Modbus-to-Ethernet bridging, and sensor fusion at sub-millisecond interrupt rates. A pin-compatible alternative within the Stellaris family is not documented in the lifecycle record; any substitute will require a board layout change.
