80 MHz Cortex-M3 — what the core speed buys you
The LM3S5951-IBZ80-C5: The Cortex-M3 core runs at 80 MHz.
Memory sizing: 256 KB Flash, 64 KB SRAM
256 KB Flash is a comfortable fit for a mid-complexity firmware image — bootloader, RTOS kernel, application code, and a modest parameter table. The 64 KB SRAM gives room for data buffers (USB packets, CAN message queues, ADC sample arrays) without needing external memory. If your application requires over-the-air updates, the Flash endurance is unspecified here, but typical Stellaris parts support 100k write/erase cycles per sector — budget for wear-leveling if you update frequently.
The 16-channel 10-bit ADC is included.
The 108-ball LFBGA (10x10 mm) package requires a 1.08 V to 1.32 V core supply.
