It packs 256 KB of Flash and 96 KB of RAM, with integrated Ethernet MAC and USB OTG — enough connectivity to serve as the main controller in an industrial panel, an HMI gateway, or a networked sensor hub. The 100-LQFP package with 65 I/O gives you room for parallel memory or a local display alongside the usual fieldbus interfaces. At 80 MHz, this Cortex-M3 handles a TCP/IP stack, a USB host stack, and a modest control loop without breaking a sweat. The 96 KB RAM gives you room for packet buffers and a few hundred tags; if your application needs heavy data logging or a graphical UI frame buffer, you will want to budget the RAM carefully or attach external memory via the EBI/EMI interface. ## Lifecycle reality — obsolete, not gone Texas Instruments has marked the LM3S9B92-IQC80-C1T as obsolete. No last-time-buy window remains; new-manufacture units are no longer available. If you are planning a new design, look at TI's current Cortex-M4 or M7 families for a pin-compatible migration path; for an existing BOM line, this is a broker-channel part going forward. ## Connectivity in a single chip The integrated Ethernet MAC and USB OTG reduce external PHY and transceiver count — you still need an external PHY for Ethernet and a USB transceiver for OTG, but the MAC and controller are on-die.","metaTitle":"Texas Instruments LM3S9B92-IQC80-C1T ARM Cortex-M3 MCU, 80MHz","metaDescription":"TI Stellaris LM3S9B92-IQC80-C1T ARM Cortex-M3 MCU, 80MHz, 256KB Flash, 96KB RAM, Ethernet, USB OTG, 100-LQFP, -40°C to 85°C.
