That means Texas Instruments has ended production; no further factory orders are possible.
The LM3S9B96-IBZ80-C1 includes an Ethernet MAC with integrated PHY, a USB OTG controller, and a CANbus interface — three network-oriented peripherals that reduce external chip count in industrial gateways, building automation controllers, and networked sensor hubs.
Yes, the LM3S9B96-IBZ80-C1 is officially obsolete. Texas Instruments has discontinued production, so new factory orders are not available. The part can still be sourced through independent distribution against an RFQ.
Texas Instruments has not published a direct pin-compatible replacement for this exact order code. The Stellaris family was succeeded by the Tiva C series (e.g., TM4C129x), but those parts have different pinouts and require a board redesign. For a drop-in alternative, check the LM3S9B96 base number for other speed or temperature variants that may still be available through surplus channels.
