The 8-channel 10-bit ADC captures analog feedback from potentiometers or current-sense resistors without a separate converter. ## 108-ball BGA — footprint and rework If your production line isn't set up for BGA, this part will add a rework step. New-production orders through the franchised channel are closed. The part is available only through independent distribution — verified surplus or last-time-buy inventory.","metaTitle":"LM3S1J11-IBZ50-C1 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1J11-IBZ50-C1 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 128 KB Flash, 20 KB SRAM, 67 I/O, industrial temp.","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":"Tray","RAM Size":"20K 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":"LM3S1J11","Program Memory Size":"128KB (128K 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/289a17a5d668d4d2eb268ac847fb8dc1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1J11-IBZ50-C1/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1J11-IBZ50-C1 obsolete?","answer":"Yes, Texas Instruments lists the LM3S1J11-IBZ50-C1 as obsolete.
