The connectivity block includes CANbus, two I²C, SPI, QSPI, SAI (for audio), and SWPMI (single-wire protocol for smartcard or NFC). The QSPI interface is particularly useful for memory-mapped external Flash or PSRAM, stretching the effective storage without loading the core bus. ## Industrial temperature range and data converters The on-chip data converters — 16-channel 12-bit ADC and two 12-bit DACs — cover analog sensor acquisition and analog output generation without external converters, reducing BOM count and board area.","metaTitle":"STM32L471VET6 ARM Cortex-M4 MCU, 80MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32L471VET6 32-bit ARM Cortex-M4 MCU, 80MHz, 512KB Flash, 128KB SRAM, 82 I/O, 100-LQFP.

Both share the same Cortex-M4 core, 80 MHz clock, and 100-LQFP footprint, so a board designed for one can often accept the other with a firmware change."},{"question":"Can STM32L471VET6 be used as a replacement for STM32L476?","answer":"Yes, in many cases the STM32L471VET6 is pin-compatible with the STM32L476 in the same 100-LQFP package. The key difference is the absence of the Chrom-ART graphics accelerator on the L471. If your application does not use the hardware graphics engine, the L471 can serve as a drop-in replacement with a firmware update."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L471VET6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L471VET6 when reusing this data.
