Product details

NRND — plan the BOM transition

This MCU carries a lifecycle status of NRND (Not Recommended for New Designs). That means TI has flagged it for eventual end-of-life; it is still available for existing production runs but should not be specced into a new board spin. 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. Sourced and quoted to order against an RFQ — availability and current pricing confirmed at quote time.

Package and assembly note

The 48-LQFP package has a 7x7 mm body. Standard reflow profile applies; check the MSL rating before the oven.

Frequently asked questions

Is the LM3S817-IQN50-C2 obsolete or NRND?

The LM3S817-IQN50-C2 is NRND (Not Recommended for New Designs), meaning TI is phasing it out. 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.

What is the LM3S817-IQN50-C2's core speed?

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.

Can the LM3S817-IQN50-C2 be used in new designs?

No — the NRND status means TI advises against new designs with this MCU. A same-family part with active lifecycle status is the safer choice for a new BOM.
