For existing designs already using this MCU, the independent channel still holds stock, but the clock is ticking on fresh TI fab runs. ## 50 MHz Cortex-M3 — enough for most control loops The Cortex-M3 core runs at 50 MHz. The connectivity block includes I²C, SPI, SSI, Microwire, and UART/USART. ## 48-LQFP — hand-solderable, but watch the thermal The package is a 48-pin LQFP with a 7x7 mm body (supplier device package 48-LQFP (7x7)). It is a hand-solderable footprint, fine for prototyping and rework.","metaTitle":"Texas Instruments LM3S628-IQN50-C2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S628-IQN50-C2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 32 KB Flash, 8 KB RAM, 28 I/O, 8×10b ADC, -40°C to 85°C, 48-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 600","Package":"Tape & Reel (TR)","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S628","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0435","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S628-IQN50-C2T/alternatives.json"},"ai":{"faq":[{"question":"What is LM3S628-IQN50-C2T's listed speed?","answer":"The core runs at 50 MHz, which is the maximum clock frequency for this Cortex-M3 device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S628-IQN50-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S628-IQN50-C2T when reusing this data.
