For a BOM that already carries this line, the procurement path is a last-time-buy or a bridge to a replacement part through independent distribution. The 48-LQFP package has a 7x7 mm body. Standard reflow profile applies; check the MSL rating before the oven.","metaTitle":"Texas Instruments LM3S817-IQN50-C2 ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 48-LQ","metaDescription":"TI Stellaris LM3S817-IQN50-C2 32-bit ARM Cortex-M3 MCU: 50 MHz, 64 KB Flash, 8 KB RAM, 30 I/O, 48-LQFP, -40 to 85°C.

It is not yet discontinued but should not be selected for new projects. Existing production can continue through last-time-buy or surplus-channel sourcing."},{"question":"What is the LM3S817-IQN50-C2's core speed?","answer":"The LM3S817-IQN50-C2 runs at 50 MHz, which is the maximum CPU clock for this Stellaris Cortex-M3 device. That throughput handles typical control loops, sensor processing, and serial communication without bus contention."},{"question":"Can the LM3S817-IQN50-C2 be used in new designs?","answer":"No — the NRND status means TI advises against new designs with this MCU.
