It is built for low-power, real-time embedded control — the AVR32 single-cycle core delivers deterministic instruction execution, which matters when the interrupt latency budget is tight. The 50 MHz ceiling is the practical limit for the USB full-speed peripheral (12 Mbps) and the 8-channel 12-bit ADC; the DMA controller offloads data movement so the core can stay in sleep longer between events. ## 48-TLLGA — footprint and assembly notes No hand-solder rework without hot-air station and flux. For a BOM that needs this exact package and memory density, the supply channel is standard distribution — no surplus-broker dependency.","metaTitle":"ATUC64L4U-D3HR AVR32 32-bit MCU, 50 MHz, 64 KB Flash","metaDescription":"Microchip ATUC64L4U-D3HR 32-bit AVR32 UC3 L MCU, 50 MHz core, 64 KB Flash, 16 KB RAM, -40°C to 85°C, 48-TLLGA.","metaKeywords":null},"attributes":{"series":"AVR®32 UC3 L","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","Series":"AVR®32 UC3 L","Package":"Bulk","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"AVR","Package / Case":"48-UFLGA Exposed Pad","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-TLLGA (5.5x5.5)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.65","priceTiers":[{"qty":65,"price":"$4.65000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/70f3e3a8e7dfcdd518c72953bdcdfb07.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATUC64L4U-D3HR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact microprocessor core of ATUC64L4U-D3HR?","answer":"The core is a 32-bit AVR single-core processor from the AVR32 UC3 L family, clocked at 50 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/ATUC64L4U-D3HR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/ATUC64L4U-D3HR when reusing this data.
