The 96 KB RAM is organized as 96K x 8, which is ample for buffering Ethernet frames or USB packets without external memory. For designs that need to store firmware updates or configuration tables, the Flash is organized as 256K x 8. ## Connectivity set: CAN, Ethernet, USB OTG, and more The LM3S9B90 integrates a CAN controller, a 10/100 Ethernet MAC with integrated PHY, and a USB OTG controller — a combination that is rare in a single MCU at this price tier. This makes the part a natural fit for industrial gateways, protocol converters, and human-machine interfaces that need to bridge fieldbus and Ethernet. Buyers should expect to work with surplus or broker inventory for this device.","metaTitle":"LM3S9B90-IBZ80-C1T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9B90-IBZ80-C1T is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 256 KB Flash, 96 KB RAM, CAN/Ethernet/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, 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":"LM3S9B90","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/494ca1076ab369c0d0fa47c7516d8c62.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package is LM3S9B90-IBZ80-C1T?","answer":"It is supplied in a 108-ball LFBGA package (10x10 mm body), surface-mount."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9B90-IBZ80-C1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9B90-IBZ80-C1T when reusing this data.
