It integrates a 12-bit ADC with 16 channels, a 12-bit DAC with two channels, and peripherals including CANbus, QSPI, SAI, and multiple I²C/SPI/UART interfaces. ## 80 MHz Cortex-M4 with FPU — real-time DSP headroom The ARM Cortex-M4 core includes a single-precision floating-point unit that accelerates FFTs, filter loops, and control algorithms without a separate DSP. At 80 MHz, the part can handle real-time motor control loops, audio processing pipelines, and sensor fusion tasks that would bog down a Cortex-M3. The 1 MB Flash and 128 KB SRAM provide enough code and data space for moderately complex firmware stacks, including FreeRTOS or a bare-metal scheduler with multiple interrupt-driven peripherals. The wide supply range down to 1.71 V lets the MCU run directly from a single Li-ion cell through most of its discharge curve, eliminating a boost regulator in many portable designs. Brown-out detect and a programmable watchdog are included on-chip for reliable operation in noisy or battery-powered systems. ## 100-LQFP package — 82 I/O in a manageable footprint The 100-pin LQFP (14x14 mm body) offers 82 usable I/O lines, enough for a parallel LCD data bus, external memory interface (EBI/EMI), and multiple serial peripherals without multiplexing. The package is hand-solderable and rework-friendly, which matters for prototyping and low-volume production. ## Active lifecycle — no near-term LTB risk STMicroelectronics lists the STM32L471VGT6TR as Active (current product). There is no announced last-time-buy or end-of-life notice. For production programs requiring multi-year supply assurance, this part carries no imminent obsolescence risk.","metaTitle":"STM32L471VGT6TR STMicro ARM Cortex-M4 MCU, 80MHz, 1MB Flash","metaDescription":"STM32L471VGT6TR is a 32-bit ARM Cortex-M4 MCU with FPU, 80MHz, 1MB Flash, 128KB SRAM, 82 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tape & Reel (TR)","RAM Size":"128K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"82","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L471","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.7553","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4420564db785aeab67c38eeacd74e22d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the differences between STM32L471VGT6TR and STM32L476VGT6?","answer":"Both share the same Cortex-M4 core, 80 MHz clock, 1 MB Flash, and 100-LQFP package. The STM32L476 variant adds a few extra peripherals such as a second DAC channel and additional communication interfaces.
