The 67 general-purpose I/O and the internal oscillator reduce external component count. It operates over the industrial temperature range of -40°C to 85°C on a 3.0 V to 3.6 V supply, and is housed in a 108-ball BGA (10x10 mm) package — a footprint suited for compact, surface-mount designs where board area is at a premium. At 80 MHz, the ARM Cortex-M3 core delivers 80 MHz clock speed. The 64 KB SRAM limits buffering. ## Obsolete — sourcing reality for the LM3S5G51-IBZ80-A1 Texas Instruments has marked the LM3S5G51-IBZ80-A1 as obsolete. No official successor order code is listed.
