Frequently asked questions
Does the LM3S9U92 need an external Ethernet PHY or can it run directly?
The integrated Ethernet block is a MAC only — it requires an external RMII PHY such as the Micrel DP83848. The MAC does not include an internal PHY. If your board already has the PHY populated, the MAC section is a direct signal-level drop-in.
What is the lead time and how do I source this part?
With an Obsolete status there is no normal lead time through authorized distribution. Sourcing is via independent distributor or surplus channel. Request traceability documentation (certificate of conformance, authorized supply chain) to confirm authenticity, and be aware that broker-channel pricing on obsolete TI ARM parts carries a significant premium and lead-time uncertainty.
