There is no LTB window to catch; the production line has already stopped. 64 KB of Flash is a mid-range budget for a Cortex-M3 — enough for a modest RTOS, a USB or CAN stack, and application logic, but tight if you are porting a large legacy codebase or adding over-the-air update staging. The 12 KB SRAM handles stack, heap, and DMA buffers; watch the linker map if your application uses double-buffered ADC or large lookup tables. If your firmware already fits on this part, the memory sizing is settled — just the sourcing question remains.","metaTitle":"LM3S1N11-IQC50-C3T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"TI LM3S1N11-IQC50-C3T Stellaris ARM Cortex-M3 MCU, 32-bit, 50 MHz, 64KB Flash, 12KB SRAM, 67 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tape & Reel (TR)","RAM Size":"12K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1N11","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/382ae1f60fbe7febad9e9e5bf72a2bb6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1N11-IQC50-C3T/alternatives.json"},"ai":{"faq":[{"question":"Can LM3S1N11-IQC50-C3T be used in new designs?","answer":"No — the part is obsolete.
