If you are filling a BOM line for a legacy product, we can secure the quantity; if you are prototyping, you should evaluate a pin-compatible successor first. ## Package and footprint — 48-LQFP 7x7 mm The LM3S618-EQN50-C2 comes in a 48-lead LQFP with a 7x7 mm body. That is a common footprint across the Stellaris family, which means a board laid out for this part can often accept a higher-density sibling with the same pinout.","metaTitle":"LM3S618-EQN50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 32 KB Flash","metaDescription":"LM3S618-EQN50-C2 from TI/Stellaris: ARM Cortex-M3 at 50 MHz, 32 KB Flash, 8K x 8 RAM, 30 I/O, -40 to 105°C.
