Includes Ethernet MAC+PHY, USB OTG, CAN, serial interfaces, 16-channel 12-bit ADC, and 65 GPIOs in a 108-ball BGA (10x10 mm). The 80 MHz core clock gives this part enough headroom to run an Ethernet TCP/IP stack (lwIP or similar) alongside a real-time control task and a USB OTG host. The 96 KB RAM is tight for a full web server buffer, but adequate for a Modbus TCP gateway or a data logger with a small frame buffer. If your firmware needs more than 512 KB Flash, you are looking at a different density tier — this part is the top of the Stellaris 9000 series in its BGA footprint. Texas Instruments has marked the LM3S9D92-IBZ80-A1 as obsolete. No factory last-time-buy window remains; the only channel is surplus and independent distribution.","metaTitle":"Texas Instruments LM3S9D92-IBZ80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Obsolete TI Stellaris LM3S9D92-IBZ80-A1 ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 96 KB RAM, Ethernet + USB OTG, 108-BGA.
