No last-time-buy window remains open through the factory; the only supply channel is the independent surplus and broker market. If you are freezing a BOM for a new design, look for a current-production Cortex-M3 or Cortex-M4 with Ethernet and CAN — the Stellaris family has been superseded by TI's Tiva C Series, though pin-compatibility is not guaranteed without a layout review.","metaTitle":"Texas Instruments LM3S8538-IBZ50-A2 ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, 64 K","metaDescription":"Texas Instruments LM3S8538-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, 64 KB RAM, Ethernet + CAN, 108-BGA.

The Tiva C Series (e.g., TM4C123 or TM4C129 parts) offers similar Ethernet + CAN functionality on a Cortex-M4 core, but the package and pinout differ — a PCB layout change is required."},{"question":"What is the pinout of LM3S8538-IBZ50-A2?","answer":"The LM3S8538-IBZ50-A2 is supplied in a 108-ball LFBGA package (10×10 mm). The pinout is documented in the Texas Instruments datasheet for the LM3S8538; the -IBZ50-A2 suffix indicates the specific temperature range and packaging variant, but the ball assignment is identical across the IBZ50 ordering code."},{"question":"Is LM3S8538-IBZ50-A2 compatible with LM3S8538-IBZ50?","answer":"The LM3S8538-IBZ50-A2 and LM3S8538-IBZ50 share the same base die and package; the -A2 suffix typically denotes a later silicon revision or a specific test program. Functionally they are interchangeable in the same socket, but verify the revision-specific errata in the respective datasheets before committing a BOM line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8538-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/LM3S8538-IBZ50-A2 when reusing this data.
