The 512 KB Flash leaves room for a full RTOS image plus application code; the 96 KB SRAM supports moderate-sized packet buffers and data arrays. If your design needs more headroom for heavy DSP or video, you would step up to a Cortex-M4 or M7 — but for most connectivity-centric embedded tasks this is a well-balanced part. ## Industrial temperature range and 100-LQFP package Official last-time-buy windows have closed, so new production stock is no longer flowing through authorized distribution. ## Peripherals and connectivity in one chip The 16-channel 12-bit ADC covers multi-sensor acquisition without an external mux.","metaTitle":"Texas Instruments LM3S9DN6-IQC80-A1 ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments Stellaris LM3S9DN6-IQC80-A1 ARM Cortex-M3 MCU at 80MHz with 512KB Flash, 96KB SRAM, Ethernet MAC, USB OTG.
