The key difference is the package: the CBU6A comes in a 48-UFQFPN (7x7 mm) tray package, while the CCT6TR is in a 48-LQFP (7x7 mm) tape-and-reel package. They are not pin-compatible, so a board spin is required to swap between them."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L151CCT6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L151CCT6TR when reusing this data.
