Frequently asked questions
What replaces the LM3S9D92-IQC80-A2T?
TI has not published a pin-compatible successor for this specific order code. The Stellaris line has transitioned to the Tiva C Series architecture, but those parts use a different pin-out and package geometry — a drop-in mechanical fit without board rework is not available through franchised distribution. Firmware porting to a Tiva C Series device would be required for a full migration.
What temperature range does the IQC80 suffix cover?
The IQC80 grade specifies -40°C to 85°C operating temperature ambient (TA). This covers the typical industrial enclosure thermal environment for factory-floor equipment, though thermal rise under full peripheral loading at 85°C ambient requires verification against the datasheet junction-to-ambient thermal resistance.
