This part was designed for industrial control, human-machine interface, and networked sensor nodes where a balance of processing throughput, memory, and connectivity is needed. The LM3S1H11-IBZ50-A1T is officially classified as Obsolete by Texas Instruments. For production runs or repair stock, procurement must go through the surplus and independent distribution channel. This is not a part to spec into a new design — the lifecycle risk is already realized. ## 108-ball BGA — layout and rework notes It is a surface-mount device shipped in Tape & Reel. The fine-pitch BGA demands careful PCB land pattern design and controlled reflow profiling. Core and I/O supply is 1.235 V to 1.365 V — a narrow, low-voltage rail that requires a clean regulated source.","metaTitle":"LM3S1H11-IBZ50-A1T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S1H11-IBZ50-A1T 32-bit ARM Cortex-M3 MCU, 50MHz, 512KB flash, 48KB SRAM, 108-BGA, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tape & Reel (TR)","RAM Size":"48K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1H11","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68920ccd04e046c9d0ddb9ddf41bb2dc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S1H11-IBZ50-A1T?","answer":"For a pin-compatible alternative, a cross-reference search within the Stellaris ARM Cortex-M3S 1000 series may yield a functional equivalent, but this must be verified against the specific BOM requirements."},{"question":"What is the price of LM3S1H11-IBZ50-A1T?","answer":"Pricing is market-driven for this obsolete part.
