The 12 KB SRAM leaves room for a few hundred bytes of stack per task plus a moderate data buffer — tight if you are doing full-frame Ethernet buffering or large FFTs, but comfortable for UART-to-CAN gateway or PWM motor-control loops. ## 108-BGA (10x10 mm) — layout and rework considerations The 108-LFBGA package (10x10 mm ball array) is a space-saver compared to a QFP of similar I/O count, but it demands a multi-layer PCB with via-in-pad or microvia routing to escape the inner rows. The Tape & Reel shipping format is standard for pick-and-place; the MSL level should be verified on the reel label before reflow.","metaTitle":"LM3S1N11-IBZ50-C5T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S1N11-IBZ50-C5T 32-bit ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 12KB SRAM, 67 I/O, -40 to 85°C, 108-BGA.","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":"12K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"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 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1N11","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/382ae1f60fbe7febad9e9e5bf72a2bb6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1N11-IBZ50-C5T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S1N11-IBZ50-C5T?","answer":"No official replacement order code is published by Texas Instruments for this part. The Stellaris ARM Cortex-M3S 1000 series is discontinued. A migration to a current-production Cortex-M3 or Cortex-M4 MCU with similar peripheral count and a 108-ball BGA footprint would be the practical path, but that requires a PCB redesign and firmware port.
