The fine-pitch leads require controlled reflow profiling and careful PCB land pattern design. The package is MSL 3 out of the bag — bake before reflow if the moisture barrier bag has been open past the floor-life window.","metaTitle":"LM3S1601-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Obsolete LM3S1601-IQC50-A2T — Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32K x 8 SRAM, 60 I/O, -40°C to 85°C, 100-LQFP.","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":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1601","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)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$26.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4169b290b2692fdd6b7d8516973e8d54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1601-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for LM3S1601-IQC50-A2T?","answer":"For a pin-compatible alternative within the same Stellaris family, the LM3S1602 is a close sibling — the key difference is that the LM3S1602 offers additional memory or peripheral features.
