The LM3S9B96-IBZ80-C5: 32-bit ARM Cortex-M3 microcontroller from the Stellaris 9000 series, clocked at 80 MHz.
80 MHz Cortex-M3 core. 96 KB SRAM provides headroom for packet buffers.
Texas Instruments has designated this part as obsolete. No official TI replacement listed.
There is no official pin-compatible replacement from Texas Instruments. The Stellaris family was succeeded by the Tiva C series (TM4C123/129), which uses a different pinout and register map. For legacy BOM maintenance, the part is available through the surplus channel; for new designs, migrate to a Tiva C or a comparable Cortex-M4 MCU.
The core runs at 80 MHz, delivering approximately 100 DMIPS from the ARM Cortex-M3 pipeline.
