Single-chip Ethernet controller for industrial control
The 108-ball BGA (10x10 mm) package and 3.0 V–3.6 V supply suit it for space-constrained, networked industrial controllers, building automation gateways, and motor-drive interfaces.
80 MHz Cortex-M3 with Ethernet — what it buys you
The 80 MHz core delivers enough throughput to run a lightweight TCP/IP stack (like lwIP) while servicing real-time control loops. The 512 KB Flash can hold a bootloader, application firmware, and a small web server; 64 KB RAM provides room for packet buffers and stack. The 46 GPIOs and 16x12-bit ADC give headroom for sensor inputs, HMI, and actuator control.
Industrial temperature range and BGA footprint
For dual-sourcing resilience, look at other Stellaris LM3S6G6x parts in the same 108-BGA footprint — they share the same pinout and peripheral map, differing mainly in Flash and RAM density.
