The Stellaris family includes higher-density and higher-speed variants (e.g., 80 MHz, 512 KB Flash), but those are not pin-compatible drop-in replacements. A redesign using a current TI ARM Cortex-M4 or Cortex-M0+ MCU is recommended for new production."},{"question":"What is the pinout and datasheet for LM3S2911-IBZ50-A2?","answer":"The pinout and full datasheet are available from Texas Instruments' archive for the Stellaris LM3S2911. The 108-ball BGA pinout is documented in the datasheet; the base product number is LM3S2911."},{"question":"Is LM3S2911-IBZ50-A2 compatible with existing Stellaris software and tools?","answer":"Yes — the LM3S2911 uses the ARM Cortex-M3 core and the Stellaris peripheral set, so it is compatible with TI's StellarisWare driver library and ARM development tools (Keil, IAR, GCC). Firmware written for other Stellaris LM3S parts with the same peripheral map will port with minimal changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2911-IBZ50-A2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S2911-IBZ50-A2 when reusing this data.
