Product details

What this Stellaris MCU brings to a control board

The TI Stellaris LM3S9D92-IBZ80-A2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 9000 series, clocked at 80 MHz with 512 KB of Flash and 96 KB of RAM. The 16-channel 12-bit ADC and 65 general-purpose I/O lines handle local sensor acquisition and parallel bus expansion without an external FPGA or CPLD.

Obsolete — sourcing reality for this line item

No last-time-buy window is open through the factory channel. No direct factory replacement exists in the Stellaris family; a pin-compatible second source is not listed in the official cross-reference records.

Frequently asked questions

Where can I buy LM3S9D92-IBZ80-A2T?

We source and quote this obsolete part to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.

What is the closest pin-compatible alternative to LM3S9D92-IBZ80-A2T?

No official pin-compatible second source or direct factory replacement is listed in the TI cross-reference records for this Stellaris part. Any substitution would require a board redesign and firmware port.

What is the listed speed of LM3S9D92-IBZ80-A2T?

The core runs at 80 MHz, which yields roughly 100 DMIPS on the Cortex-M3 pipeline.

What compliance documentation does TI provide for LM3S9D92-IBZ80-A2T?

TI provides RoHS and REACH compliance declarations for this part. UL and IEC certifications are not listed in the standard documentation set for this component.
