Production has ceased, and available stock is the last inventory. For replacement options, check the official successor from the Stellaris family or evaluate a pin-compatible Cortex-M3 alternative."},{"question":"Where can I buy LM3S308-EGZ25-C2T in tape and reel?","answer":"The LM3S308-EGZ25-C2T is available in Tape & Reel packaging. We source it through independent distribution and quote it to order against an RFQ. Availability and current pricing are confirmed at quote time."},{"question":"What is the difference between LM3S308-EGZ25-C2T and LM3S308-EGZ25-C2?","answer":"The 'T' suffix typically indicates Tape & Reel packaging for automated assembly, while the non-T variant may come in tube or tray. The electrical specifications and pinout are identical between the two."},{"question":"Can LM3S308-EGZ25-C2T be used with standard ARM Cortex-M3 development tools?","answer":"Yes, the Stellaris MCU uses the ARM Cortex-M3 core, so it works with standard ARM development tools including Keil MDK, IAR EWARM, and GCC-based toolchains. Texas Instruments provides the StellarisWare driver library and peripheral examples."},{"question":"What is LM3S308-EGZ25-C2T's listed speed?","answer":"The core runs at 25 MHz, which provides sufficient throughput for moderate control loops and serial communication tasks typical of industrial embedded applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S308-EGZ25-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S308-EGZ25-C2T when reusing this data.
