The Stellaris family was migrated to the Tiva C series, but a drop-in footprint and register-map match is not guaranteed — any migration requires a full firmware and layout review. ## 100-LQFP footprint — layout constants The 67 available GPIOs occupy most of the perimeter, so fan-out via blind vias under the package is not required — a two-layer board can route the signals if the decoupling caps are placed close to the supply pairs.","metaTitle":"Texas Instruments LM3S1J11-IQC50-C1T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments Stellaris LM3S1J11-IQC50-C1T 32-bit ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 20K x 8 RAM, 100-LQFP, -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":"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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/289a17a5d668d4d2eb268ac847fb8dc1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1J11-IQC50-C1T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1J11-IQC50-C1T obsolete?","answer":"No official successor part number has been issued, so any replacement requires a design migration to a current TI MCU family."},{"question":"What is the replacement for LM3S1J11-IQC50-C1T?","answer":"TI has not published a direct pin-compatible replacement for this specific order code.
