The 64 KB SRAM (organized as 64K x 8) is shared between code data and stack; if you need large frame buffers or multiple protocol buffers, plan for external SRAM or a part with more on-chip RAM.","metaTitle":"LM3S9997-IBZ80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S9997-IBZ80-C3 32-bit ARM Cortex-M3 MCU at 80MHz with 256KB Flash, 64KB 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":"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-C3/alternatives.json"},"ai":{"faq":[{"question":"Does LM3S9997-IBZ80-C3 support Ethernet?","answer":"Yes, the LM3S9997-IBZ80-C3 integrates an Ethernet MAC+PHY as part of its connectivity block, alongside CANbus and USB OTG."},{"question":"What is the replacement for LM3S9997-IBZ80-C3?","answer":"No official replacement part number is published by Texas Instruments.
