The 96 KB RAM gives headroom for moderate packet buffering and data logging. ## Obsolete — sourcing reality for this part This part is marked obsolete by the manufacturer. For a BOM line that requires this exact order code — for a legacy board in a machine tool, a panel retrofit, or a field repair — the only channel is surplus or independent distribution.","metaTitle":"LM3S9B90-IQC80-B1 Stellaris ARM Cortex-M3 MCU, 80MHz, 256KB Flash","metaDescription":"LM3S9B90-IQC80-B1 is an obsolete Stellaris ARM Cortex-M3 MCU with 80MHz core, 256KB Flash, 96KB RAM, Ethernet/CAN/USB.
