The Stellaris family has been superseded by the Tiva C series (TM4C123x), which offers a similar Cortex-M4 core with more memory and peripherals but a different pinout. A board respin is required. For existing designs, the closest functional path is to evaluate the TM4C123GH6PM or a comparable current-production Cortex-M3 from NXP or STMicroelectronics."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S812-IQN50-C2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S812-IQN50-C2 when reusing this data.
