This part targets industrial control nodes, motor drives, and automotive body electronics where CAN connectivity and a moderate memory footprint are required. This is the official notice that while the part remains available for existing production builds, it is not intended for new design starts. For a buyer managing a BOM line that already uses this MCU, the NRND flag means you have time to secure last-time-buy quantities or qualify a replacement, but you should not commit a new project to this order code. ## 50 MHz Cortex-M3 — what the speed rating buys you The 50 MHz core clock is the usual Cortex-M3 sweet spot for control-loop tasks that need more throughput than a 48 MHz Cortex-M0 but don't require the 80–120 MHz tier. With zero-wait-state Flash access at this frequency, the part can handle a CANopen stack, a USB device interface, and a PID loop without stalling the bus. The 64 KB SRAM gives enough headroom for double-buffered ADC data or a modest RTOS heap.","metaTitle":"LM3S5737-IQC50-A0T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S5737-IQC50-A0T 32-bit ARM Cortex-M3 MCU at 50 MHz with 128 KB Flash, 64 KB SRAM, CAN/USB.","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 5000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"61","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5737","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":"$13.7112","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38b03106a267df1019dd902dd40d5344.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5737-IQC50-A0T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S5737-IQC50-A0T?","answer":"The evidence does not list an official successor order code from Texas Instruments.
