The connectivity set includes Ethernet MAC, USB OTG, two CAN 2.0B controllers, LIN, and multiple UART/SPI/I²C interfaces — covering the fieldbus and backplane communication needs of an industrial controller or gateway. ## Memory, ADC, and GPIO budget for control applications The 384 KB Flash (384K x 8) stores firmware and bootloader; the 96 KB SRAM (96K x 8) supports moderate data buffering — enough for a 100+ node CANopen master or a small web server on the Ethernet port. A 16-channel 12-bit ADC samples analog inputs from sensors or potentiometers; the 60 general-purpose I/O pins connect to external memory, displays, or keypads via the EBI/EMI bus. Texas Instruments has classified the LM3S9U90-IBZ80-A2 as Obsolete. Each lot is verified for authenticity and traceability before quoting. The 108-BGA (10x10 mm) package and 1.235-1.365 V core supply are non-negotiable for a drop-in replacement — no second-source pin-compatible part is documented in the Stellaris family. Housed in a 108-ball LFBGA (10x10 mm body), the LM3S9U90-IBZ80-A2 requires a multi-layer PCB with via-in-pad or microvia fan-out for the 0.80 mm ball pitch. The tray packaging supports automated pick-and-place assembly.","metaTitle":"Texas Instruments LM3S9U90-IBZ80-A2 ARM Cortex-M3, 80MHz","metaDescription":"Texas Instruments LM3S9U90-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80MHz, 384KB Flash, 96KB SRAM, Ethernet/USB OTG/CAN, -40-85°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":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tray","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, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"60","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":"LM3S9U90","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d5a3c7f4e6d8156d26ead837ff8fd0d0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9U90-IBZ80-A2/alternatives.json"},"ai":{"faq":[{"question":"What is the core speed and memory of the LM3S9U90-IBZ80-A2?","answer":"The ARM Cortex-M3 core runs at 80 MHz.
