What this Stellaris MCU brings to the board
The Texas Instruments LM3S6C11-IBZ80-A1T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 6000 series, clocked at 80 MHz with 512 KB of Flash and 64 KB of RAM.
80 MHz Cortex-M3 — what the speed buys you
The 80 MHz core on the Cortex-M3 architecture gives this part enough headroom to run a lightweight TCP/IP stack alongside control loops without needing an external Ethernet controller. For a panel-mounted PLC or a remote I/O slice, that means one less chip on the BOM and a simpler layout.
Memory sizing and the firmware budget
512 KB of Flash and 64 KB of RAM split as 64K x 8. The Flash holds a full application with a small RTOS and a TCP/IP stack; the RAM covers packet buffers and a modest variable pool.
Package and rework reality
This part comes in a 108-ball LFBGA, 10x10 mm body. The BGA footprint means a four-layer PCB minimum and a hot-air rework station with a fine nozzle.
Temperature grade and where it runs
Buyers should treat this part as a candidate for a bridge buy or a final order rather than a long-term production commitment.
