This part is packaged in a 108-ball LFBGA (10x10 mm) with 72 general-purpose I/O lines. ## 80 MHz core — timing budget for networked control The 80 MHz Cortex-M3 core, combined with the DMA controller and the peripheral set, handles protocol stacks for Ethernet, USB, and CAN without a separate network coprocessor. The 512 KB Flash is large enough for a TCP/IP stack plus application code; the 96 KB RAM supports multiple packet buffers. The internal oscillator keeps BOM count low, though an external crystal improves clock accuracy for Ethernet timing. ## Obsolete — last-time-buy and surplus sourcing The lifecycle status is Obsolete. TI has ended production of this Stellaris-series device. For existing BOM lines, procurement must go through independent distribution or the surplus market. ## 108-ball BGA — layout considerations The 108-LFBGA package measures 10x10 mm with a 0.8 mm ball pitch typical for this class. The fine-pitch BGA requires a multi-layer PCB with microvia capability for fanout. Decoupling should follow the supply pin map — the core runs from a 1.235 V to 1.365 V rail, separate from the 3.3 V I/O supply.","metaTitle":"TI LM3S9DN5-IBZ80-A1 ARM Cortex-M3 MCU, 80MHz, 512KB Flash","metaDescription":"Texas Instruments Stellaris LM3S9DN5-IBZ80-A1 ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 96KB RAM, Ethernet, USB OTG, CAN, 108-LFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S9DN5-IBZ80-A1","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tray","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","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","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":[{"question":"Is LM3S9DN5-IBZ80-A1 obsolete?","answer":"Yes, the lifecycle status is Obsolete.
