The 72 GPIOs and rich peripheral set (Ethernet MAC+PHY, CAN, USB OTG, multiple UART/SPI/I²C, PWM, QEI) mean it can serve as a system controller without external interface ICs for most common fieldbuses. ## 108-ball BGA — layout and assembly The part comes in a 108-LFBGA package, supplier device package 108-BGA (10x10 mm). Supply voltage is 1.235 V to 1.365 V for the core. The internal oscillator is available, but an external crystal or clock source can be used for tighter timing. ## Peripheral set — Ethernet, CAN, USB, and more Connectivity includes CANbus, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, and USB OTG. The 16-channel 12-bit ADC handles analog sensing. Peripherals like DMA, PWM, and watchdog timer offload the core for real-time tasks. This is a fully featured MCU that can serve as the main processor in a distributed control node or a protocol bridge.","metaTitle":"LM3S9DN5-IBZ80-A2T Stellaris Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9DN5-IBZ80-A2T is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 512 KB Flash, 96 KB RAM, Ethernet, CAN, USB OTG.","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, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"72","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":"LM3S9DN5","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":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9DN5-IBZ80-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9DN5-IBZ80-A2T when reusing this data.
