Product details

The core supply is 1.235 V to 1.365 V.

80 MHz Cortex-M3 — what the speed means for the BOM

80 MHz on the Cortex-M3 core. The 384 KB Flash and 96 KB RAM support a moderate firmware image with TCP/IP stack and application logic.

Obsolete — sourcing and lifecycle reality

Texas Instruments has marked the LM3S9U96-IBZ80-A1 as obsolete. For new designs, evaluate the TM4C129x series (same Cortex-M4F core, pin-incompatible but software-migratable) or a third-party ARM MCU with Ethernet and USB OTG.

Frequently asked questions

What is a direct replacement for LM3S9U96-IBZ80-A1?

No official pin-compatible replacement is listed. The TM4C129x series from TI offers a similar peripheral set on a Cortex-M4F core but requires a board redesign. For the same BGA footprint, check the remaining channel inventory of the LM3S9U96-IBZ80-A1 itself.

Does LM3S9U96-IBZ80-A1 have Ethernet connectivity?

Yes, it integrates an Ethernet MAC+PHY, along with USB OTG, CAN, and multiple serial interfaces.

Where can I buy LM3S9U96-IBZ80-A1?

This obsolete part is sourced through independent distribution. Submit an RFQ for current availability and pricing — stock and lead time are confirmed at quote time.

What is LM3S9U96-IBZ80-A1's listed speed?

The core runs at 80 MHz on a 32-bit ARM Cortex-M3 processor.
