The LM3S9D96-IBZ80-A1 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 9000 series, clocked at 80 MHz with 512 KB of Flash program memory and 96 KB of RAM.
At 80 MHz, the Cortex-M3 core runs a lightweight TCP/IP stack alongside a control loop without external RAM. The 512 KB Flash holds a moderate application image.
Yes, Texas Instruments has classified the LM3S9D96-IBZ80-A1 as obsolete. No factory production or last-time-buy is available; supply is limited to independent-distributor surplus stock.
Texas Instruments has not designated a direct replacement for this order code. A board redesign using a current-production Cortex-M4 or Cortex-M7 MCU from TI's Tiva or MSP432 families would be the typical migration path.
