The 96 KB SRAM is split across the core memory map, so the Ethernet controller's descriptor rings and packet buffers can be allocated without starving the application heap. For designs that log data or store configuration tables, the Flash endurance and sector-erase granularity (typically 1 KB sectors on this family) matter when planning wear-leveling for frequent updates. ## Industrial temperature grade and 100-LQFP package The 100-pin LQFP (14x14 mm body) gives 72 general-purpose I/O, enough to interface a parallel LCD, an external memory bus (EBI/EMI), and multiple serial peripherals without a CPLD for port expansion. The supply range is a narrow 1.235 V to 1.365 V core — a dedicated 1.3 V rail is required, not a 3.3 V or 1.8 V drop-in. That rail needs its own LDO or switcher; the I/O bank runs at 3.3 V separately. The LM3S9DN6-IQC80-A1T is officially classified as Obsolete by Texas Instruments. No last-time-buy window remains open through the factory channel. Sourcing this part now runs through independent distribution and the surplus market. No official TI successor order code is listed for this exact configuration.","metaTitle":"LM3S9DN6-IQC80-A1T Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S9DN6-IQC80-A1T, Stellaris ARM Cortex-M3S 9000 series 32-bit MCU. 80MHz core, 512KB Flash, 96KB SRAM, Ethernet + USB OTG + CAN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tape & Reel (TR)","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"72","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9DN6","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S9DN6-IQC80-A1T?","answer":"No official TI successor order code is documented for this exact configuration.
