Frequently asked questions
Is the LM3S9B95-IQC100C0T still active or officially obsolete?
The product status is Obsolete (EOL-hot), meaning the last-buy window is either live or recently closed. Lock allocation now through franchised channels before the window closes — independent stock carries spot-market premium and counterfeit risk.
Does the LM3S9B95 Ethernet MAC auto-negotiate MDI/MDIX crossover, or do I need an external PHY?
The on-chip Ethernet MAC implements the media access layer only. An external Ethernet PHY is required for the physical layer; auto-MDI/MDIX crossover is a PHY-side feature, not a MAC-side one.
What package dimensions does the 100-LQFP give me for the panel cutout?
The supplier device package is 100-LQFP with a 14×14mm body. Pin pitch is 0.5mm with standard lead span for this pin count — direct mechanical swap into existing production panels designed around the TI Stellaris LQFP-100 footprint.
