The 512 KB Flash (organized as 512K x 8) holds a substantial firmware image — enough for a TCP/IP stack, application logic, and a bootloader with room to spare. The 64 KB SRAM (64K x 8) supports moderate data buffers and runtime variables. For designs that need more headroom for Ethernet packet buffers or data logging, check whether the application fits within this memory envelope; if not, a sibling with larger SRAM in the same 100-LQFP footprint may be the better pick. ## Ethernet on-chip — saves a separate MAC and external PHY interface The integrated Ethernet MAC is the standout connectivity feature. ## Package and footprint — 100-LQFP (14x14 mm) No BGA routing complexity or via-in-pad requirements. The supplier device package is 100-LQFP (14x14), confirming the footprint. Surface-mount only.","metaTitle":"LM3S6G65-IQC80-A2T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S6G65-IQC80-A2T 32-bit ARM Cortex-M3 MCU at 80 MHz with 512 KB Flash and 64 KB SRAM.
