The LM3S8730-EQC50-A2T is officially obsolete per Texas Instruments' lifecycle status. No direct replacement has been announced by the manufacturer, so new-production runs are not available through the factory channel.
Texas Instruments has not announced a direct pin-compatible replacement for this Stellaris MCU. Within the same family, other 100-LQFP variants may serve as a functional alternative, but verify memory and peripheral compatibility against your BOM.
