Product details

80 MHz Cortex-M3 with integrated Ethernet MAC — the BOM-fit tier

The LM3S6G11-IQC80-A1: The integrated Ethernet MAC controller handles frame processing on-chip; an external PHY chip and magnetics are still needed for the physical connection.

The 512 KB Flash can hold a TCP/IP stack, RTOS kernel, and application code. The 64 KB SRAM is byte-addressable; buffer Ethernet frames and sensor data carefully.

100-LQFP (14x14 mm) — layout and rework notes

Verify the mechanical drawing for an exposed pad; if present, stitch it to ground with thermal vias.

For a production BOM, this is a green light for new designs, though the Stellaris series has been in the market for years, so monitor Texas Instruments' PCN feed for any future transition notices.

Frequently asked questions

Does LM3S6G11-IQC80-A1 support Ethernet?

Yes, it has an integrated Ethernet MAC controller. You still need an external PHY chip and magnetics for the physical RJ-45 connection, but the MAC handles the IEEE 802.3 frame processing on-chip. The connectivity list also includes I²C, IrDA, LINbus, Microwire, SPI, SSI, and UART/USART.
