Product details

80 MHz Cortex-M3 — processing headroom for protocol stacks

The 80 MHz core delivers enough throughput to run a lightweight TCP/IP stack, USB host/device drivers, and dual CAN message handling simultaneously without saturating the bus. That matters for designs where the MCU handles both application logic and real-time network responses — the 80 MHz clock keeps the CPU from becoming the bottleneck.

EOL — sourcing reality for this part

Peripheral set — what you get on-chip

On-chip peripherals include a 16-channel 12-bit ADC, internal oscillator, brown-out detect, POR, PWM, watchdog timer, and a DMA controller. This is a full-featured control-and-communications MCU that can serve as a single-chip gateway or sensor-fusion node.

Frequently asked questions

Is LM3S9U92-IBZ80-A2T obsolete and what is the recommended replacement?

Yes, this part is obsolete with no official successor from Texas Instruments. Any replacement will require a board-level redesign to a different MCU family. We can help source remaining inventory through independent channels.

Does LM3S9U92-IBZ80-A2T support Ethernet and USB OTG?

Yes, it integrates an Ethernet MAC+PHY and a USB OTG controller, along with dual CAN interfaces. No external PHY is needed for 10/100 Ethernet.

What is the pinout and datasheet for LM3S9U92-IBZ80-A2T?

The pinout and full datasheet are available from Texas Instruments. The 108-BGA package has 65 GPIOs; the datasheet provides the ball-map and electrical characteristics.

What are the equivalent parts for LM3S9U92-IBZ80-A2T?

No pin-compatible equivalent exists from TI. A functional replacement requires evaluating a different Cortex-M3 or M4 MCU with Ethernet, USB OTG, and dual CAN. Contact us for cross-reference support.
