The Cortex-M3 single-cycle multiply helps with deterministic response. ## Memory and connectivity — what the 256 KB Flash and 64 KB SRAM let you do 256 KB Flash is comfortable for a bootloader plus a moderate application stack (e.g., a Modbus TCP slave with a web server). The 64 KB SRAM leaves room for a couple of large buffers — one for the Ethernet frame, one for CAN message queues. If you need more than that, you'll be looking at external memory or a larger part in the family. ## Industrial temperature rating — deployment context ## Lifecycle status — obsolete, sourced to order Texas Instruments has marked the LM3S8938-EQC50-A2T as obsolete (EOL). No official successor part is listed in the evidence. For new designs, consider a current-generation Stellaris or Tiva-C series MCU with similar peripheral mix.","metaTitle":"LM3S8938-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"LM3S8938-EQC50-A2T is an obsolete Stellaris ARM Cortex-M3 MCU from TI. 50 MHz core, 256 KB Flash, 64 KB SRAM, CAN/Ethernet, -40 to 105°C.
