For production or repair BOMs that require this exact suffix, the supply channel shifts to independent distribution — verified surplus, new-old-stock, or broker-sourced inventory. ## What the 50 MHz core means for timing closure At 50 MHz the Cortex-M3 pipeline executes most single-cycle instructions, so a tight control loop (e.g., a 10 kHz PID with sensor read and PWM update) leaves ample margin. The Flash wait-state configuration matters — at this clock speed the internal prefetch buffer typically keeps the pipeline fed without a wait state penalty for sequential code, but branching into scattered lookup tables may introduce a single-cycle stall. Budget for that if your interrupt service routine jumps across multiple Flash pages.","metaTitle":"LM3S1J11-IQC50-C0 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Obsolete LM3S1J11-IQC50-C0 32-bit ARM Cortex-M3 MCU from TI Stellaris series. 50 MHz core, 128 KB Flash, 20K x 8 SRAM, 67 I/O, -40°C 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":"Tray","RAM Size":"20K 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":"LM3S1J11","Program Memory Size":"128KB (128K 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/289a17a5d668d4d2eb268ac847fb8dc1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy LM3S1J11-IQC50-C0?","answer":"This obsolete order code is sourced through independent distribution. Submit an RFQ for current availability and pricing — each quote is confirmed against live inventory at the time of request. No stock or price figures are published here because the supply position changes."},{"question":"Is LM3S1J11-IQC50-C0 obsolete?","answer":"Yes, Texas Instruments lists this part as obsolete. There is no documented TI successor with the same pinout, so any replacement requires a board-level redesign or a verified surplus source for the exact order code."},{"question":"What is the replacement for LM3S1J11-IQC50-C0?","answer":"No official replacement order code is recorded in the lifecycle data. Engineers evaluating a drop-in should check the Stellaris family for a currently active Cortex-M3 part in the same 100-LQFP footprint, but TI has not published a direct cross-reference.
