The main difference across variants is typically the Flash and RAM density — the RCH6 variant sits at 256 KB Flash / 32 KB SRAM. For a drop-in replacement with the same pinout, look at other STM32F091xCH6 or STM32F091xCT6 parts, but confirm the memory sizing matches your firmware image."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F091RCH6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F091RCH6TR when reusing this data.
