If your firmware image or data buffer exceeds this, you are looking at a larger member of the Stellaris family or a migration to a newer Cortex-M4 or M7 part. ## Peripheral set — Ethernet, CAN, USB OTG on one chip The 16-channel 10-bit ADC covers analog sensing for voltage, current, or temperature inputs. ## Package and temperature — 108-BGA, industrial range Supply voltage is a tight 1.235V to 1.365V core rail — that means a dedicated low-noise regulator, not a shared 3.3V or 5V rail. Plan for a separate 1.25V or 1.3V LDO with adequate decoupling.","metaTitle":"LM3S9997-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"Obsolete Stellaris LM3S9997-IBZ80-C5 ARM Cortex-M3 MCU. 80MHz core, 256KB Flash, 64KB RAM, Ethernet, CAN, 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":"Tray","RAM Size":"64K 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":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9997","Program Memory Size":"256KB (256K 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/a16760f1b1ed2b544492e5acf48839b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9997-IBZ80-C5/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S9997-IBZ80-C5 obsolete?","answer":"Yes, the LM3S9997-IBZ80-C5 is officially Obsolete per the lifecycle record.

In practice, a migration to a newer Cortex-M4 or M7 family (such as the TM4C series) with similar peripheral integration is the typical path, though it will require a board spin and firmware port."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9997-IBZ80-C5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9997-IBZ80-C5 when reusing this data.
