The 64 KB RAM is notably generous for a Cortex-M3 in this Flash class; it can hold a moderate Ethernet TCP/IP stack plus a CANopen object dictionary without tight buffer management. ## Sourcing reality — obsolete, no direct replacement listed Texas Instruments has marked the LM3S8530-IQC50-A2T as obsolete. If the design is still in development, consider migrating to a currently active Stellaris or Tiva-C family part; a pin-compatible drop-in is not guaranteed, but the peripheral set (Ethernet + CAN) is common across the Stellaris line.","metaTitle":"Texas Instruments LM3S8530-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S8530-IQC50-A2T 32-bit ARM Cortex-M3 MCU at 50 MHz with 96 KB Flash, 64 KB RAM, Ethernet MAC, CAN, 100-LQFP, -40°C to 85°C.
