The 48 KB SRAM is the tighter resource here — a full Ethernet frame buffer plus two CAN message objects eats into that quickly. This part is officially obsolete per the manufacturer. No last-time-buy windows remain open; new production has ceased. For an existing design already qualified on the LM3S9L97, the only path is surplus or broker-channel procurement. The 100-LQFP (14x14 mm) is a common footprint.","metaTitle":"Texas Instruments LM3S9L97-IQC80-C5 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"TI LM3S9L97-IQC80-C5 Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB Flash, 48KB SRAM, Ethernet + CAN + USB OTG, 100-LQFP, -40°C to 85°C.
