The 65 GPIOs and external bus interface (EBI/EMI) let it connect to displays, memory-mapped peripherals, or FPGAs without a glue-logic layer. ## 256 KB Flash / 96 KB SRAM — sizing the firmware and data buffers The 256 KB program Flash is sized for a TCP/IP stack, CANopen or EtherCAT slave stack, and a modest application layer — think a remote terminal unit (RTU) or a protocol converter. The 96 KB SRAM (organized as 96K x 8) gives enough headroom for two full Ethernet frames plus CAN message buffers and a small heap. If your firmware image pushes past 256 KB or you need a larger packet buffer, you are looking at a different density tier. ## 108-BGA (10x10) — footprint and layout notes 108-ball LFBGA (10x10 mm) package. 65 GPIOs and EBI/EMI signals require a four-layer PCB with a solid ground plane. Core supply is 1.235 V to 1.365 V rail. It does not carry an AEC-Q100 automotive grade, so it is not qualified for under-hood or chassis-mounted applications. The 85°C ceiling also means it is marginal for sealed enclosures near a hot power supply without airflow — budget the thermal margin.","metaTitle":"Texas Instruments LM3S9B92-IBZ80-C5 ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments Stellaris LM3S9B92-IBZ80-C5 ARM Cortex-M3 MCU at 80MHz with 256KB Flash, 96KB SRAM, Ethernet MAC, CAN, USB OTG.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S9B92-IBZ80-C5","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":"65","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9B92","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":"$30.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5c502cb512502878adb8a8ea415e40a6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9B92-IBZ80-C5/alternatives.json"},"ai":{"faq":[{"question":"Does LM3S9B92-IBZ80-C5 support Ethernet and CAN?","answer":"Yes.
