The 65 GPIOs, combined with PWM, QEI, and I²S, also support motor-drive feedback and audio processing in the same chip. The Stellaris line was acquired by TI and later phased out in favor of the Tiva-C and SimpleLink families, but no direct pin-compatible drop-in replacement was published for this specific BGA variant. ## 108-ball BGA — layout and rework notes The 108-LFBGA package measures 10x10 mm with a 0.8 mm ball pitch typical of this density tier. Surface-mount assembly requires a solder paste stencil matched to the BGA land pattern; X-ray inspection is recommended after reflow to check for head-in-pillow or voiding. For rework, a preheat profile that keeps the entire board above 100°C before local hot-air reflow reduces the risk of cold joints on the inner balls. The supplier device package code is 108-BGA (10x10).","metaTitle":"LM3S9U96-IBZ80-A1T Stellaris Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9U96-IBZ80-A1T Stellaris ARM Cortex-M3 MCU, 80 MHz, 384 KB Flash, 96 KB SRAM, Ethernet, USB OTG, -40°C 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":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tape & Reel (TR)","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"65","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9U96","Program Memory Size":"384KB (384K 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":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is LM3S9U96-IBZ80-A1T obsolete and what is the EOL status?","answer":"Yes, Texas Instruments lists the LM3S9U96-IBZ80-A1T as obsolete.
