No last-time-buy window remains open; production has ended. No manufacturer-declared direct replacement or pin-compatible successor exists for the LM3S6618-EQC50-A2 within the Stellaris family. Any cross-reference or equivalent must be evaluated on a form-fit-function basis by the design team, considering the 50 MHz core, 128 KB Flash / 32 KB SRAM, Ethernet MAC, and 100-LQFP footprint. A migration to a current-production Cortex-M3 or Cortex-M4 part from another series or vendor will likely require a PCB respin and software port. Core and I/O share a single 2.25 V to 2.75 V supply rail.","metaTitle":"LM3S6618-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, Obsolete","metaDescription":"LM3S6618-EQC50-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 128 KB Flash, 32 KB SRAM, Ethernet MAC, and industrial temp range.
