Partitioning is a firmware design decision — typical secure OTA bootloader schemes reserve 64–128KB of FLASH for the secondary-stage loader, leaving 384–448KB for the primary application. SRAM headroom for dual-buffer stacks, CANopen managers, and 24-channel 12-bit ADC DMA is application-dependent and must be validated against the compiled memory map."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F746BET6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F746BET6 when reusing this data.
