It carries 384 KB of Flash program memory and 64 KB of RAM, with 60 general-purpose I/O lines and a 16-channel 12-bit ADC. The part is housed in a 108-ball BGA (10x10 mm) and operates from -40 to 85°C, making it suitable for industrial control, sensor interfacing, and communication gateways that need a mid-range Cortex-M3 with multiple serial protocols. The 80 MHz core delivers enough throughput for real-time control loops and protocol bridging without the overhead of a full RTOS — a common fit for factory automation nodes and instrumentation front-ends where deterministic response matters. Connectivity includes I²C, SPI, UART/USART, LIN, IrDA, and Microwire. The 16x12-bit ADC samples analog inputs directly. ## Obsolete — sourcing reality for this MCU 384 KB Flash is sized for firmware images that include a communication stack (e.g., Modbus RTU over UART or a lightweight TCP/IP offload) plus application logic, with room for field-upgradeable parameters. 64 KB RAM supports moderate data buffering — adequate for a control loop with a few hundred tags, but not for frame-grabber or large-logger applications.","metaTitle":"LM3S1G58-IBZ80-A1T Stellaris ARM Cortex-M3 MCU, 80MHz, 384KB Flash, 64KB RAM","metaDescription":"Obsolete LM3S1G58-IBZ80-A1T Stellaris ARM Cortex-M3 MCU. 80MHz core, 384KB Flash, 64KB RAM, 60 I/O, -40 to 85°C, 108-BGA.
