The connectivity block is the headline differentiator: CANbus, Ethernet MAC+PHY, USB OTG, plus multiple UART, SPI, I²C, and SSI serial interfaces. For a system that needs to talk to a plant-floor network over Ethernet and to a local HMI over USB, this part eliminates an external network coprocessor. ## Memory and peripheral headroom for a connected design 384 KB of flash and 96 KB of SRAM give the application stack room for a TCP/IP stack, a USB device stack, and the main control loop. The 16-channel 12-bit ADC samples analog sensors without an external converter; the PWM and QEI peripherals handle motor feedback directly. The 100-LQFP package (14x14 mm body) with 65 I/O lines provides enough GPIO for a parallel LCD interface or an external memory bus (EBI/EMI is listed in the connectivity set). The internal oscillator saves a crystal on the BOM for applications that can tolerate the internal accuracy; for precision timing, an external crystal feeds the main oscillator input. Texas Instruments lists the LM3S9U92-IQC80-A2T as obsolete. The Stellaris family was migrated to the Tiva C series several years ago; no direct pin-compatible replacement from TI carries the same peripheral mix. For a BOM line that cannot be redesigned, the existing firmware and PCB layout are tied to this exact order code. A volume quote should confirm lot traceability and date code range before committing the production run.","metaTitle":"LM3S9U92-IQC80-A2T Texas Instruments Stellaris MCU, 80MHz","metaDescription":"Texas Instruments LM3S9U92-IQC80-A2T Stellaris ARM Cortex-M3 MCU, 80MHz, 384KB flash, 96KB RAM, 100-LQFP.
