The Texas Instruments LM3S9DN6-IBZ80-A1T is a Stellaris® ARM® Cortex®-M3S 9000 series 32-bit single-core microcontroller running at 80 MHz. The 108-LFBGA (10x10 mm) package and 1.235 V to 1.365 V core supply target compact, power-sensitive industrial control and networked embedded systems.
80 MHz Cortex-M3 — what it buys you
At 80 MHz the Cortex-M3 core handles real-time control loops, protocol stacks (Ethernet, USB, CAN), and data acquisition without external logic. The 72 general-purpose I/O lines give enough headroom for a modest HMI or multi-axis motion controller.
The 108-ball LFBGA (10x10 mm) is a fine-pitch BGA — rework requires hot-air station and X-ray inspection.
