The Ethernet MAC runs the TCP/IP stack; the CAN controllers handle the drive bus; the USB OTG can serve a configuration port or a data-logging stick. The 48 KB RAM is tight for heavy buffering — plan your packet queues accordingly. Texas Instruments has marked the LM3S9L97-IQC80-C3T as Obsolete. No last-time-buy window remains through the factory channel. If you are qualifying a new design, look for a pin-compatible or functionally equivalent current-production Stellaris or Tiva C Series device; the LM3S9L97 sits in the 100-LQFP footprint, and TI's Tiva TM4C129x family is a common migration target for Ethernet+CAN applications.","metaTitle":"Texas Instruments LM3S9L97-IQC80-C3T ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments Stellaris LM3S9L97-IQC80-C3T ARM Cortex-M3 MCU at 80MHz, 128KB Flash, 48KB RAM, Ethernet/CAN/USB OTG, 100-LQFP.
