For a BOM already qualified on the LM3S2948, the NRND flag signals the need to evaluate a successor or secure last-time-buy inventory before the end-of-life window closes. ## 108-ball BGA — board-level assembly notes The LM3S2948-IBZ50-A2T is supplied in a 108-LFBGA package with a 10x10 mm body (Supplier Device Package 108-BGA). This is a fine-pitch BGA requiring a controlled reflow profile, X-ray inspection for voiding and solder joint integrity, and a clean stencil design for the 0.5 mm or 0.65 mm ball pitch typical of this package class. Decoupling should follow TI's recommendations for the Stellaris family, typically a 0.1 µF ceramic per supply pin plus a bulk 10 µF on the main rail. ## Connectivity and memory headroom for control applications The 52 I/O pins provide enough GPIO for a sensor array or a motor-drive interface with encoder feedback. The 8-channel 10-bit ADC is adequate for monitoring analog signals like temperature, current, or voltage feedback at moderate sample rates.","metaTitle":"Texas Instruments LM3S2948-IBZ50-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments Stellaris LM3S2948-IBZ50-A2T 32-bit ARM Cortex-M3 MCU at 50MHz with 256KB Flash, 64KB RAM, CANbus, 52 I/O, 108-LFBGA, -40 to 85°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 2000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2948","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.4115","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7c7600c415358413d168c14428e3ae63.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2948-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2948-IBZ50-A2T obsolete?","answer":"It is not yet discontinued, but TI recommends against using it in new designs.
