It carries 256 KB of program Flash and 64 KB of SRAM, with an integrated Ethernet MAC+PHY. The 50 MHz Cortex-M3 runs a single-threaded protocol stack plus application logic. The 38 GPIOs and 8-channel 10-bit ADC cover sensor readout and relay control. ## EOL status and sourcing reality This part is marked Obsolete by the manufacturer. There is no factory last-time-buy window open; procurement should treat this as a surplus-channel part and plan for a redesign if volume production continues.","metaTitle":"LM3S6938-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"Obsolete LM3S6938-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB RAM, Ethernet, industrial temp, 108-BGA.
