With 128 KB of program Flash and 64 KB of SRAM, this MCU fits in the mid-density tier of the Stellaris family. The Flash is adequate for a moderate-complexity control stack with a real-time OS, a CANopen or Modbus protocol layer, and application logic. The 64 KB RAM leaves room for a few large buffers — useful for CAN message queues or a display frame buffer — but you will need to budget carefully if the application includes extensive data logging or a TCP/IP stack without external memory.","metaTitle":"LM3S2776-IQR50-A0T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S2776-IQR50-A0T, 32-bit ARM Cortex-M3 MCU at 50 MHz with 128 KB Flash, 64 KB RAM, 33 I/O, CANbus, -40°C to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, 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":"Not For New Designs","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2776","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":"$11.3140","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2776-IQR50-A0T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2776-IQR50-A0T obsolete?","answer":"This means TI continues to manufacture it for existing customers, but the part is no longer supported for new design-ins.
