Stock is confirmed at RFQ; quantities are lot-specific and date-code traceable. ## 80 MHz Cortex-M3 — what the core delivers The ARM Cortex-M3 core runs at 80 MHz — a 32-bit single-core pipeline with hardware divide and single-cycle multiply. This sets the throughput ceiling for the application; the actual instruction execution rate depends on flash wait states and bus contention from the DMA controller. On-chip memory comprises 384 KB of flash for program storage and 48 KB of SRAM for data. The flash is large enough for a full protocol stack plus application logic; the SRAM budget of 48 KB constrains the runtime heap and stack depth, particularly with multiple active communication buffers. ## Peripheral set and analog acquisition The part integrates 67 general-purpose I/O lines, a suite of serial interfaces including I²C, SPI, SSI, UART/USART, IrDA, LIN, and Microwire, plus an external bus interface (EBI/EMI) for memory-mapped peripherals. The 8-channel 12-bit ADC provides analog input for multi-sensor acquisition without an external converter. On-chip peripherals include brown-out detection, power-on reset, a PWM module, a watchdog timer, and a DMA controller — enough to offload data movement from the core without an external CPLD or FPGA. ## Package, supply, and temperature grade Housed in a 108-ball LFBGA (10x10 mm body), the 0.80 mm pitch BGA demands a multi-layer PCB for fan-out — a two-layer board will not break out the inner balls. The supplier device package is 108-BGA (10x10).","metaTitle":"LM3S1F11-IBZ80-A2T Texas Instruments Stellaris MCU, 80MHz","metaDescription":"LM3S1F11-IBZ80-A2T, Texas Instruments Stellaris ARM Cortex-M3 MCU, 80MHz, 384KB Flash, 48KB RAM, 108-BGA.","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 1000","Package":"Tape & Reel (TR)","RAM Size":"48K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1F11","Program Memory Size":"384KB (384K 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/da482a497db9073f889a6a92b2dda55b.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S1F11-IBZ80-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S1F11-IBZ80-A2T when reusing this data.
