On-chip program memory is 384 KB of Flash, with 48 KB of SRAM — enough to hold a moderate application stack plus a real-time operating system footprint without external memory. The 32-bit single-core architecture and the internal oscillator simplify the BOM — no external crystal is required for the core clock, though the connectivity peripherals (EBI/EMI, I²C, SPI, UART, etc.) may still need a precision reference for certain baud rates. Housed in a 100-LQFP package with a 14x14 mm body, the LM3S1F11-IQC80-A2T requires a 4-layer PCB for reliable fan-out of the 0.50 mm pitch leads. The 67 I/O lines include an 8-channel 12-bit ADC for analog sensor inputs.","metaTitle":"Texas Instruments LM3S1F11-IQC80-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S1F11-IQC80-A2T ARM Cortex-M3 MCU, 80MHz, 384KB Flash, 48KB RAM, 100-LQFP.","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":"100-LQFP","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":"100-LQFP (14x14)","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":[{"question":"What is the closest pin-compatible alternative to LM3S1F11-IQC80-A2T?","answer":"The base product number LM3S1F11 belongs to the Stellaris ARM Cortex-M3S 1000 series, which is discontinued.
