The primary difference is that the STM32L476 adds a few extra peripherals — specifically a second SAI audio interface and a DFSDM (digital filter for sigma-delta modulators) — which the STM32L475 omits. For designs that do not need those peripherals, the STM32L475VCT6 is a cost-optimized drop-in alternative with identical pinout and software compatibility."},{"question":"Is STM32L475VCT6 compatible with the STM32L4 series peripherals?","answer":"Yes. The STM32L475VCT6 is a member of the STM32L4 series and shares the same peripheral set and register layout as the rest of the family. Code written for the STM32L476 or STM32L496 will port directly, with the caveat that the STM32L475 lacks the DFSDM and second SAI — any firmware that accesses those peripherals will need conditional compilation or a driver stub."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L475VCT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L475VCT6 when reusing this data.
