The 64 KB SRAM leaves room for two moderate-sized packet buffers plus a real-time OS heap. ## Obsolete — sourcing reality for the BOM line This part is officially obsolete per the manufacturer's lifecycle status. No direct pin-compatible successor from TI's Stellaris line has been published; the Stellaris family was transitioned to the Tiva™ C series, which uses a different pinout and supply architecture. For existing production boards that cannot be redesigned, the only channel is the independent surplus and broker market.","metaTitle":"LM3S8738-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"Obsolete LM3S8738-IQC50-A2 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 50 MHz, 128 KB Flash, 64 KB SRAM, CAN/Ethernet.
