The 512 KB Flash holds a full firmware image with room for OTA update staging; the 64 KB SRAM supports moderate packet buffering and stack usage. For designs that need to handle multiple protocol stacks or larger data sets, the 64 KB SRAM is the constraint to budget against.","metaTitle":"Texas Instruments LM3S6C65-IBZ80-A1T ARM Cortex-M3 MCU","metaDescription":"TI Stellaris LM3S6C65-IBZ80-A1T 32-bit ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 64 KB RAM, Ethernet, 108-BGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S6C65-IBZ80-A1T","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6C65","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)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5201edd73f6507996bad42358827830d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6C65-IBZ80-A1T/alternatives.json"},"ai":{"faq":[{"question":"Can LM3S6C65-IBZ80-A1T be used at 85°C?","answer":"Yes."},{"question":"What is the difference between LM3S6C65 and LM3S6965?","answer":"The LM3S6C65 and LM3S6965 are both Stellaris Cortex-M3 parts with the same 80 MHz core, 512 KB Flash, and 64 KB SRAM.
