The 60 general-purpose I/O lines and 16-channel 12-bit ADC suit it for industrial gateways, motor-control interfaces, and networked sensor hubs that need both wired and local connectivity. ## 80 MHz Cortex-M3 — what it means for throughput The core runs at 80 MHz. The Ethernet MAC includes an integrated PHY, so no external transceiver is needed. ## Connectivity mix: Ethernet, USB OTG, CAN This part is officially obsolete per TI's lifecycle status. No last-time-buy window remains open. For new production or repair of existing boards, the only channel is the independent surplus and broker market. There is no pin-compatible direct replacement from TI; any migration requires a full design re-evaluation, likely to a newer Cortex-M4 or M7 family. It will hold up in factory-floor cabinets, outdoor telecom shelters, and engine-bay-adjacent electronics without a conformal-coat requirement — though the 100-LQFP package benefits from a clean assembly process to avoid solder-joint stress at the low end.","metaTitle":"Texas Instruments LM3S9D90-IQC80-A2T ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Obsolete TI Stellaris LM3S9D90-IQC80-A2T ARM Cortex-M3 MCU, 80 MHz, 512KB Flash, 96KB RAM, Ethernet, USB OTG, CAN, 100-LQFP, -40 to 85°C.
