The 30 GPIOs and 6-channel 10-bit ADC give it enough I/O for a sensor-fusion node or a motor-drive interface without needing external muxing. ## NRND — what it means for a production BOM That means TI has stopped actively promoting it for new projects, but it's not yet discontinued — you can still source it through independent distribution for existing production runs or legacy repairs. There's no official successor listed in the lifecycle record, so if you're qualifying this for a new build, budget time for a pin-compatible cross-search across the Stellaris family or a migration to a newer Cortex-M4 part. ## 48-LQFP footprint and rework notes Housed in a 48-LQFP with a 7x7 mm body, this is a straightforward hand-solder or hot-air rework package.","metaTitle":"LM3S617-EQN50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S617-EQN50-C2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 600 series, 50 MHz core, 32 KB Flash, 8 KB SRAM, 6x10b ADC, 48-LQFP, -40°C to 105°C.","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":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"30","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S617","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.0425","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8de192a1ebb7e318a6baa2cb4743357.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S617-EQN50-C2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S617-EQN50-C2 obsolete or still available?","answer":"It remains available through the surplus and broker channel for existing production and repair work, but TI no longer recommends it for new design-ins."},{"question":"What is the replacement for LM3S617-EQN50-C2?","answer":"For a pin-compatible drop-in, you would need to cross-reference other Stellaris 600-series parts with the same 48-LQFP footprint and supply voltage; a migration to a newer Cortex-M4 or M0+ family may be required for new designs."},{"question":"What alternatives are there to LM3S617-EQN50-C2?","answer":"Within the same Stellaris 600 family, parts with higher Flash or RAM but the same 48-LQFP footprint and 3.3 V supply may be pin-compatible.
