For a BOM line that is already qualified, the NRND flag is a signal to evaluate a migration path before a formal EOL notice appears. ## Supply voltage and temperature grade — where it runs That means the board's power supply needs to be a regulated 2.5 V rail, not a generic 3.3 V LDO. ## Peripherals and data conversion — what is on-chip The brown-out detect and POR supervise the supply, and the PWM and WDT suit motor-control and watchdog-supervised applications. The internal oscillator reduces external component count, though a crystal can be added for tighter timing.","metaTitle":"LM3S3748-IQC50-A0 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S3748-IQC50-A0 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 64 KB SRAM, 61 I/O, -40 to 85°C, 100-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 3000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, QEI, 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":"LM3S3748","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":"$35.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bf56620112e7c54a1ede14c5e50ee38a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S3748-IQC50-A0/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S3748-IQC50-A0 obsolete?","answer":"Texas Instruments still supports existing production, but new designs should not start with this part.
