The 32 KB SRAM and 128 KB Flash support a TCP/IP stack and application code. Texas Instruments has marked the LM3S8630-IBZ50-A2T as obsolete. No official successor is listed in the Stellaris 8000 family; the Stellaris line was folded into the Tiva-C portfolio after TI acquired Luminary Micro. For a pin-compatible drop-in you would need to evaluate the Tiva TM4C123x series or an equivalent Cortex-M4 part, but the footprint and peripheral map differ.","metaTitle":"Texas Instruments LM3S8630-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"TI Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB SRAM, Ethernet & CAN.
