It is not a high-end application processor — you are not running Linux on it — but for a dedicated control node that reports over Ethernet, the speed is well matched to the peripheral set. ## Obsolete — sourcing reality and replacement path Texas Instruments has marked the LM3S6918-IBZ50-A2 as Obsolete. That means no further factory orders are accepted; the only channel for this exact order code is the surplus and independent-distribution market. ## Package and layout note The 38 general-purpose I/O are mapped to the outer balls — check the pinout diagram for Ethernet-specific ball assignments before laying out the magnetics.","metaTitle":"LM3S6918-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256KB Flash, Ethernet","metaDescription":"LM3S6918-IBZ50-A2 is a 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 50 MHz, 256KB Flash, 64KB RAM, Ethernet, industrial temp.
