An internal oscillator keeps the BOM count low — no external crystal required for the core clock. On-chip peripherals include a 6-channel 10-bit ADC, PWM outputs, a watchdog timer, DMA, and brown-out detect/reset — enough for a motor-control or sensor-fusion node without an external ADC or supervisor. No pin-compatible drop-in replacement is documented — any alternative requires a board-level evaluation. ## Industrial temperature grade and supply range The 64-LQFP package has a 0.50 mm pitch and a 10x10 mm body. A 4-layer PCB with a solid ground plane under the QFP is typical for signal integrity at 50 MHz; the exposed pad (if present) should be soldered to the ground plane for thermal relief.","metaTitle":"TI LM3S1776-IQR50-A0 Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"Texas Instruments LM3S1776-IQR50-A0 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB flash, 64 KB RAM, 64-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":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Obsolete","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1776","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.7498","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1776-IQR50-A0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S1776-IQR50-A0 and how do I get a price?","answer":"Sourced through independent distribution against an RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S1776-IQR50-A0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S1776-IQR50-A0 when reusing this data.
