Runs a lightweight TCP/IP stack alongside a CANopen master node and Modbus RTU slave with headroom for PID loop updates. ## 256 KB Flash and 64 KB RAM — sizing the firmware budget The 256 KB Flash holds a moderate application: a FreeRTOS kernel, lwIP stack, CANopen stack, and a few hundred lines of application code fit comfortably. The 64 KB SRAM leaves about 40 KB free after the stack and RTOS heap for packet buffers and data arrays. If your application requires a full web server with TLS or a large data-logging buffer, this part will run out of RAM — consider an external SRAM or a larger sibling in the Stellaris family. The 108-ball BGA (10x10 mm) requires a 4-layer PCB with via-in-pad for the fine-pitch balls — not a two-layer board part. The BGA package also limits hand-solder rework; plan for reflow assembly. ## Obsolete — sourcing reality and alternatives","metaTitle":"LM3S8962-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"Texas Instruments LM3S8962-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, Ethernet + CAN, -40 to 85°C.
