The Texas Instruments LM3S308-EGZ25-C2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris® M3S 300 series, clocked at 25 MHz and built around a single-core architecture.
The 25 MHz clock rate defines instruction throughput for time-critical tasks. The 4K x 8 RAM limits buffering; plan stack and DMA buffers accordingly.
Yes, the LM3S308-EGZ25-C2T is end-of-life (EOL). 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.
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.
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.
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.
The core runs at 25 MHz, which provides sufficient throughput for moderate control loops and serial communication tasks typical of industrial embedded applications.
